2015 BMW 435i xDrive, Front Tire Repairs

Mark: Hi, it's Mark from Top Local. I'm here with Bernie Pawlik Pawlik Automotive in Vancouver. Vancouver's best auto service experience. We have exciting news, now 24 time winners of best auto repair in Vancouver, 24 times. Come on, give somebody else a chance. No, they're the best as voted by their customers and we're talking cars. How are you doing Bernie? 

Bernie: Doing very well. 

Mark: So today's victim 2015 BMW, 435i xDrive. BMW has the longest names in history I think. Something was going on with the front tires on this vehicle, what was happening? 

Bernie: Yeah, so the vehicle came to our shop for not a province inspection. It was coming from Ontario. And whenever you license a vehicle in BC, you've got to have a provincial safety inspection done on the vehicle to make sure it's compliant. So we did that and found that one of the front tires had a bulge in the sidewall, which is definitely a fail item. 

Mark: Can you repair a bulging sidewall?

Bernie: No, sidewall damage on a tire is not repairable. The only repair you can actually do on a tire is like a nail or a puncture in the tread area. And if you get too close to the edge of the tread, that's not repairable, but if it's sort of central to within an inch of the edge, you're good. Maybe even three quarters repairable. Sidewall no. 

Mark: So how does the sidewall get a bulge? Is it eating too much fat food? 

Bernie: Yeah. Yeah, it's bad, bad air. Usually what I find, especially with this car, it's got low profile tires. If you hit a pothole that's usually a way to get a bulge in the sidewall, but what happens is it actually causes internal damage to the tire.

So it's allowing air to escape from the sort of inside sealed area of the tire to the outer layers of the tire. And it's definitely indication of tire damage. And of course, if the sidewall blows, you know, pop it with a pin or something that you're going to lose all your air. So it's one step away from you know, disaster.

Mark: So I know, or I become aware that BMW, the later ones are using run flat tires. How are they to change? Is there anything different about run flats on a maintenance level? 

Bernie: Well run flat tires, the whole reason they have them is so that if you actually do lose air in a tire, so you have a puncture, you're actually able to drive a short distance, maybe 50 kilo meters, not at a real high speed to get your tire repaired.

And these cars don't have a spare tire. A lot of newer vehicles don't have spare tires and they don't have run flats. But the nice thing about a run flat as you can actually still drive and get your tire fixed. Changing them is a bit more work because the sidewalls are exceptionally stiff. That's the only way you can have a tire that you can run low on air. Any average tire, of course, it'll just squash up and ripped to shreds once  the air goes out of it. So it's kind of a neat design. Very expensive, by the way, like run flat tires, they're almost twice the price of a non run flat tire. So you can expect to pay a lot more money for the tires when you need to replace them. 

Mark: So once you were doing inspection, did you find anything interesting that you think caused the problem? 

Bernie: We did and sometimes you think, well, it's just a tire repair. Why are we doing a podcast? Well I've often been preachy about the idea of don't get plug repairs for tires. You know, the proper way to repair a tire is to take a tire off the rim, seal it with a patch plug, you know, inspect the inside of the tire. And when we took the tire off, we found some very interesting stuff. So let's get into some pictures and we can look at reasons why you don't want to just use a plug on a tire.

So there's our 435i with a nice dull wrap finish. This is what we found when we took the tire off. This is the inside sidewall, severely cracked, chunks of little bits of rubber inside the tire. This tire had probably had been run for a long time low on air. Who knows how long, hence the bulge, which I figured may have been more recent, but obviously it wasn't.

We looked further at the tire, this is a plug. Something you can pull into a garage, you could probably even get this yourself. Just poke it in with a piece of whatever rubbish material and a bit of glue. And that plugs the tire and your leak's fixed. Not a recommended or endorsed way to repair a tire.

And the reason why, I mean, they generally work. They do hold air in the tires because you're not getting a chance to inspect the tire. So there's the inside. There's the plug that stays in there. But you can see this crack in the sidewall. This was probably there long before this plug was put in and who knows how long this person has been driving on a tire.

That's really frankly, very dangerous. If this was not a run flat tire, it would blow out very easily because the run flat is a harder sidewall. There's at least a little bit of protection, but not much. When you look at this crack and this one all the way around the radius, the diameter of the tire. When you have a flat, get it fixed properly is what I'm saying. 

Mark: Don't use a plug. 

Bernie: Yeah. Don't use a plug. Now I do have to say there was one exception, I had a customer who he used to take his camper van on these rough logging roads. And he said, I usually get like one popped tire every time I go. So he goes, I bring a plug kit and a compressor. And I thought, well, you know, that's probably a valid way to repair it because you're not near a shop where you can actually take the tire off and repair it. And I'm like, well, you know, I guess that's okay. But you know, if you're repairing it immediately and not driving it, it's probably okay.

But if you're going into a shop, if they can't take the tire off the rim repair. You really shouldn't be dealing with them. 

 Mark: You mentioned this was a provincial inspection. So did you need to do any other repairs for the car to pass the safety rules in BC? 

Bernie: Yeah. So we found a couple issues with the car. One is the rear brakes were worn out. So they needed new pads and rotors on the rear. And being a BMW, there was actually an indicator and a warning on the dash saying rear brakes needed to be replaced. So the owner knew that when he came in and the other thing that needed to be done was there was tinting on both side windows and the windshield. You're not allowed to have tinting on front windows or windshields in British Columbia. Those windows have to be absolutely clear, just like the factory, no tint whatsoever. You can have the back windows tinted black, but not the fronts. So that had to be removed.

So, you know, as a preparation if you're watching this podcast, if you had tinted windows, if you want to speed the process up, you can get it removed. We fortunately have a neighbor who is in the tinting business. So he also removes tinting. So it's very convenient for us and our customers. But just so you know, tinting will fail your test. 

Mark: So you found one cracked sidewall, did you have to replace both tires? 

Bernie: We did both tires because the tire on the left side, the one that was good, you know, the tread was starting to get worn. This tire actually had better tread than the other side. It's entirely possible that they may have had a bulged sidewall problem. I had a Mercedes with low profile tires, and a couple of times I'd have to replace the front tires after winter because you hit a pothole, Oh, there's a bulge in the sidewall. Those weren't run flat tires, but you know, nonetheless, once you get a bulge, it's dangerous.

But yeah, we replaced both. I mean, it's always better, especially on the front to have both and the treads are much thicker on these tires. We replaced the left tire, you know, there's no damage whatsoever in the sidewall because of course they'd never been run low on air. If you run a tire low on air for a while, it does damage the tire. Many times we go to do a flat repair and we pull the tire off and it's damaged because it's been run low on air. So keeping it full is critical for the long tire life and your safety.

2017 Chevy Bolt, Blind Spot Warning Repair

Mark: Hi, it's Mark from TLR. I'm here with Bernie Pawlik, Pawlik Automotive in Vancouver. Vancouver's best auto service experience. 23 time winners of best auto repair in Vancouver as voted by their customers. We're talking cars. How you doing Bernie? 

Bernie: Doing very well. 

Mark: So a fresh electric car, 2017 Chevy Bolt that had a blind spot lane warning repair. What was going on with this vehicle? 

Bernie: Yeah, so the owner came to us. They apparently hit their back bumper on something and the blind spot warning and lane changing warning system stopped working in the vehicle. So they brought it to us to look at and see what we could do to repair it.

Mark: Now this is electric, so what kind of testing and diagnosis did you do? And was it any different than normal? The way you start. 

Bernie: For something like this? No, we basically hook up our trusty Snap-on scan tool, which has all the software for GM vehicles, including the Chevy Bolt. Do we say Bolt or Volt? It's funny how you can get confused with that. Anyways we hooked up our scan tool and interrogated the body system and found a store trouble code, which kept repeating for a communication error with the rear vehicle modules. So I can't remember the exact description of the code, but it kind of confirmed what we figured might be going on with the vehicle. So that was basically what we found through the scan tool part of it, which is again, as the initial part of the diagnosis. It's the basic starting point of the diagnostic. 

Mark: Gives you a general area where the problem probably lays basically. 

Bernie: Exactly. There's something communicating. There's a computer in the front or body control computer somewhere that's not communicating with the computer's in the rear of the vehicle related to the lane keeping system and blind spot warning. 

Mark: So what were your next steps? 

Bernie: Next step, pull the rear bumper, inspect the wiring. Now I'd mentioned they'd hit something. It was very subtle because the bumper wasn't crushed or cracked. There's a little tiny mark where it hits something. But we pulled the bumper off and we found a wiring connector that was just munched with all the wires you know, crushed and you know, popped apart, so we found the problem is pretty evident right then and there.

And I should probably just get into some pictures right now because that's where the interesting stuff lies. So there's our 2017 Chevy Bolt.

So this is a little bit of damage on the bumper. You can barely see it. There's a tiny little crease right there and a little mark there. You know very minimal amount of damage.  Fortunately didn't damage, these are parking sensors, these round dots didn't damage any of those, didn't damage any lights. It kinda makes you wonder what with all these controls, why did he even hit something? But you know, I've got vehicles that have those and it's, I don't know, you can still hit stuff, it still happens. 

Broken wiring connector.  There's basically what we found.  So this is like a two in one connector. These pins and pieces are all popped apart. You can see this is like the weather seal. Very important to have these sealed, obviously because they're in the outdoor environment. And there's another picture here this shows another piece of the connector that's all munched. So you can kind of see what we're up against. 

Mark: Okay. So let me ask you a little bit of question. Perhaps we haven't prepared for, which is why in the heck did this happened from such a small little bump. 

Bernie: Well, what we believe happened and I'm not sure if I have a picture. Well, you know what, I'm going to jump ahead. This is the repaired connector, but this big aluminum plate here, this is the actual bumper. That other piece that has a little crease, is the plastic cover. And there's some foam in there. Behind this piece, there's a clip where the wiring connectors, this wiring connector that's all munched up is supposed to go. And it basically hooks in behind there. So it shouldn't ever get hit by anything, it's protected. But for some reason, what we conclude happen is as the person's backed up, this wiring connector was in behind in between the bumper, that metal piece and the plastic and just got crushed.

So bit of crappy luck for these people, because you know, this is only in one location. Had they backed up even a few inches over it wouldn't have cracked this, but for some reason it did. So that's basically why it happened. And when we repair it, of course, we ensured that everything was on the proper side.

So if something like this were to happen again, the wiring connectors out of harm's way. Now, why it was like that, it's hard to know. Was it a sloppy installation at the factory? Was this bumper off previously for some other repair or did somehow when it hit pull the thing apart and in a sort of two-part process of creasing in it it pulled the wiring connector apart and crushed it. It's kind of hard to know. Nonetheless, it was broken. So bit of crappy luck for the owners of this vehicle is what I can say.  

So as for repairs. Yes. There was a couple of options. One was to get new wiring harnesses from GM. I believe it was over $1,800 for the, they don't sell the connectors or plugs. You have to basically buy the whole wiring harness. So the wiring harness...

Mark: Wait a minute, wait a sec, $1,800 for a wiring harness?

Bernie: Yes. It's not an outlandish price but that's only one end of it. The one in the back bumper was I believe about $300. So the back bumper is complicated because it's got two radar sensors. I should have taken some more pictures, but it's got two radar sensors on the corner of the rear bumpers.

Plus it's got the parking sensors and of course it's got a light, so there's quite a few items as you can see. This is the body side of the wiring that we repaired. But you know, of course it's way too much money, but the $1,800 wiring harness, is a very, very complex piece of wiring. It's obviously not just a few wires. It's this plus it goes through the whole vehicle. We figured a much better, faster, and way more, way more cost effective way would be to put new wiring connectors, not an easy job, but we used these Deutsch connectors. These are a really high quality connector. They use a special crimper to crimp the wires on much like you get in a factory. I mean, it's OEM factory quality. All weather sealed. Available in a variety of sizes for different wire gauges and yeah, it's a great quality repair. 

So quite a few hours worth of work to take everything apart and do it right. But you know, the amount of time it took us to do that would probably less time than changing the wiring harness to the front of the vehicle. The only downside of course, if the back bumper ever got, you know, really destroyed whoever would be doing the future repairs would have to customize the wiring harness, but that's not a big deal in the greater scheme of things. 

Mark: So with all these electronic fanciness in there, that adds a tremendous amount of complexity, but in this case, because a lot of that stuff wasn't damaged particularly, it's just the wiring end of things that you're having to repair.

Bernie: Yeah, exactly. But there's a lot in there. I don't know the price of these radar sensors, but I mean, there's a lot to them. I bought a new GM truck recently.  It's a nice for trailer towing. It's got all sorts of cameras and sensors and warning lights, and led lights to shine down the back to look at your cargo when it's dark out and just all sorts of stuff. But I cringe to think how much this mirror would cost to fix you know, oh and it tilts in, it's a little fancier. 

So I read an article just recently about, you know a Subaru that had a headlight problem and it was like $6,000 for a new headlight for a Subaru. I mean, that's, you know, we just don't expect those kinds of things out of an average kind of car that was $6,000, maybe on a Mercedes, but not a Subaru. And, you know, there's, if you get the Mercedes and BMW, it gets even worse. So, you know, with all these fancy features that we have on cars, there's a price to be paid and trying to avoid hitting something is really important. Of course, these things are supposed to prevent you from doing it, but it's, I don't know.

Mark: We can keep out smart anything.

Bernie:  Exactly. You know, it's not hard to do sometimes, so they help out. So yeah there's a lot of added complexity for sure. 

Mark: So the Chevy Bolt is a fully electric vehicle. What do you think of them? Are they reliable? 

Bernie: Yeah, I think they're really awesome. I mean, there are fairly new, so, I mean, there's not many repairs that we do on these kinds of things at this point in time. I would say though, there probably will be very little as there's not much in the way maintenance. And that's what kind of brings people back often, other than repairs or things breaking.

 We'll just look at some more pictures of the vehicle. Some under hood shots because I find it always interesting and looking at these things. There's a good under hood view.

2017 Chevy Bolt, Blind Spot Warning Repair
2017 Chevy Bolt, Blind Spot Warning Repair

This is what you find in the engine compartment. I guess it's the motor compartment now of the Chevy Bolt.

So what's familiar. Well there's brake fluid here, the brake master cylinder, but a lot of this is all electronically controlled now. You've got computer modules here that you'd find. There's the 12 volt battery there which powers and runs all the other accessories. I believe this is an inverter I be wrong here. I didn't really research enough of what all the bits and pieces are under the hood of this vehicle. But everything with orange cables is high voltage, and this is all high voltage cabling.

The electric drive motor and unit will be down below here. You can see there's two coolant reservoirs here as well. There's some AC or heating pipes here. So again, I'm not sure how the system works and a lot of these things I tend to learn on an as needed basis. So I can definitely see an AC fitting here.

So a lot of electric vehicles will use the AC system for heat and cooling as well. So you know, there's some stuff that looks the same and a lot of stuff that's different. And then of course, repairs will be substantially different to do than you would normally do. As a matter of fact, I could see three coolant reservoirs here. So interesting.

The other thing I found interesting is this is the radiator cap. The radiator cap is like, there isn't even really a radiator there. They're so small. But what's interesting, it's only five PSI pressure, very low pressure. I mean, most internal combustion engines are up around the 15, some of this highest 18 PSI range because there's a lot of heat and pressure.

So again, these are very low pressure systems. So leaks, they won't occur as easily as they would on an internal combustion engine. They just don't have the same amount of heat generated as you would. 

Mark: Is there any other maintenance other than just maybe topping up fluids and brakes and suspension systems on an electric vehicle? 

Bernie: It's pretty much it. They have tire pressure warning, so. You know, I don't like to recommend that people just drive a car without having it inspected every once in a while. But when a car is brand new, you know, you can probably honestly drive one of these cars for a couple of years without even taking it in for service. You can top up your washer fluid, it'll have a cabin air filter that needs to be changed. I mean, there's no engine air filter anymore. The cabin air filter if you're a somewhat handy, is probably not difficult to do yourself. Rotating tires is an important thing to keep the wear even. 

And I think, you know, once the car gets a few years old, having an annual inspection will be an important thing because you never know, things do start to where at that point. You've got weather issues, road salt and that kind of thing. If you live in that kind of climate, getting it on your brakes. So brakes will need service from time to time, even though they will last a long time. Having service on brakes depending on where you live is going to be an important thing to do once every year, once every couple of years. Rotating your tires on a regular basis and just inspecting the steering and suspension, make sure there's no loose parts. It might be computer monitoring for all your fluids and tire pressures, but it doesn't monitor things like ball joints. 

There might be some kind of technology around that with nanotechnology in the future where everything will be told to you. But I think that's a little ways out. Give it five years. Yeah. But I think the key thing is when a warning light comes on, there's something that's going to need to be addressed. And that's when something will need to be repaired. I think it's hard to know what electric vehicles, what the issues are, because they're pretty new. You know, in Teslas, I mean, they've been around for over 10 years and they kind of keep to themselves. There's not so much published information out there. You know, but things like bad connections and corrosion will certainly be an issue, especially in areas where there's a lot of harsh winters and road salt. I think those things will start causing problems. Places like Arizona, where you got none of that, maybe nothing, hard to know.

Mark: If you need some service on your electric vehicle. They've actually serviced quite a few. The guys to call are Pawlik Automotive in Vancouver, (604) 327-7112. They've worked on Teslas.

2008 Honda Civic, Transmission Bearing

Mark: Hi, it's Mark from TLR. I'm here with Bernie Pawlik, Pawlik Automotive in Vancouver, 23 time winners, best auto repair in Vancouver as voted by their customers. And we're talking cars. How are you doing Bernie? 

Bernie: Doing very well. 

Mark: 2008 Honda Civic had a transmission problem. What was going on with this car?

Bernie: Yeah, so this is a standard transmission and the owner had mentioned that when he had the clutch, either in or out, there was certain times there were some noises coming from the transmission. Figured either there was something wrong with the clutch or the actual transmission itself. So this is the concern we were dealing with. Transmission noises.

Mark: So how do you test or diagnosed those kinds of issues? 

Bernie: Yeah so first of all, of course, a road test to verify the concern and see where the issue's occurring. And then from there, we test it on the hoist with some listening equipment, stethoscopes and things to just listen and see when the condition occurred.

Because a lot of times you can kind of get an idea, is that a clutch problem or a transmission problem based on whether the clutch is engaged or disengaged or what gear you're in. So between the road test and the driving test, we kind of thought the clutch was more of the issue, but our next step was to actually remove the transmission to inspect. And actually found that the transmission input shaft bearing was actually the item making the noise. It was excessive of play in the barrel. 

Mark: So is this a pretty involved repair? 

Bernie: Yeah, it's a transmission removal and transmission disassembly. So yeah, there's a fair bit of work involved. Definitely more than if it was a clutch problem. Because we have to take the transmission apart and either, you know, overhaul it or repair it, there's a fair bit of work to be done.

Mark: So if the bearing is worn out, wouldn't that cause damage to the rest of the transmission? 

Bernie: Well it can, and it depends on how long you leave that kind of thing. I'll just get into a picture right now. 

So there's a view of the transmission. 

2008 Honda Civic, Transmission Bearing
2008 Honda Civic, Transmission Bearing

These are all the gears, basically the gear sets and the transmission. The bell housing is this part down here. And the bell housing basically attaches the transmission to the engine. And inside this large area here that I'm sort of swirling my mouse pointer around is where the clutch is located. This large gear here, this is the final drive gear. This is a differential section, so it's a transaxle actually not a transmission.

And the transaxle is basically a transmission, which are these parts here. Again, if you're reading this, you're not going to see it, but with the most pointer you can see, these are the transmission gears here. It's a five speed transmission, and this is the final drive section here, which is the differential section.

Anyway, so the bearing the red arrow basically points to the area where the bearings were worn. We actually ended up replacing two bearings in this one. The main shaft bearing, which I believe is over here. We basically replaced both those bearings in that area, but yeah, if a bearing wears bad enough in the gears, develop enough play between them it can start breaking gear teeth or causing damage in that area.

So also metal filings can be flung around inside the transmission, which can cause some  pretty serious damage. Fortunately there's a magnet inside the transmission and all the metal filings and where from the bearing, bits and pieces. And I didn't take a picture of it.

I should have, but all the bits and pieces, all went onto the magnet, which was perfect. So the magnet did its job and saved the rest of the transmission. So all we had to do is replace the bearing.

This is a closeup, that's the main bearing that was worn out. And again, that's a kind of a closer view of that. This is the reverse idler gear here just for reference, but that's basically the inside of the transmission. As I said there's two bearings we replaced in this area and that solved our issue.

 Mark: So you have to do take the transmission apart. Is this a fairly common for you guys? How do you proceed with this kind of repairs is something that you do on a regular basis? 

Bernie: Well as far as commonality, you know, the input shaft bearing failure on Hondas has actually been going on for quite a long time. So you know, as reliable as these cars are, that is one of the areas that does tend to go. We've seen it on Acura vehicles as well. So if you have a Honda with a standard transmission, an input shaft bearing failure is not an uncommon issue. It's not like guaranteed to screw up issue like Subaru head gaskets, for instance, on a 2.5 litre Subaru, but  it is common enough and it does happen. And normally, you know, with the transmission repair, often we would just change all the bearings. But in this case, because it's a fairly common input shaft bearing issue, and the other bearings we can spin them and get a feel for them.

They all seem to be in pretty good shape and all the metal filings and all gone onto the magnet. We felt it was pretty safe. We just cleaned the inside of the transmission, cleaned all the gears and just replaced the bearings that were worn. 

Mark: So you mentioned, this is a common failure item. What kind of year range are we talking about?

 Bernie: You know, I'm thinking that in the 2000, you know, the first decade of 2000s, it's common around then. I think even late 90s, there was issues. I might be a little off on that, but you know, certainly in the 2000s era that's definitely an issue.

Mark: So you always say Honda's are very reliable. Is this still the case with the 2008 Civic, with a manual transmission? 

 Bernie: Yeah, I still think it's a really reliable car. As I was saying a moment ago. I mean, it's not like if you have one with a manual, it's guaranteed the input shaft bearing is going to go bad. It does happen on some models. You know, the only other defect I've seen on these Honda's is around this model year again, is sometimes the engine blocks crack. 

We had one a while ago where, and this is not entirely uncommon issue, although we've only ever seen it with one client, but the engine block cracks and they have to replace the engine. So that's not a good thing, but again, it's an issue that happens, but not really commonly. So something to watch out for. Now the thing is, you know, if you don't have any antifreeze in your engine, you can certainly accelerate that process. But these are for, you know, people maintain their car well and have proper antifreeze. It's just some defect in the engine block. 

So it's probably one of those things where you have an inspection on the vehicle. It'll look fine, you buy it and it might happen. But those are just sort of two things to look out for on these cars. Otherwise I'd say they're pretty much bullet proof reliable.

Mark: Is there any way to lessen the odds of this transmission bearing going bad, like changing your transmission fluid a little bit more than what's recommended.

Bernie: Well, I'd say changing the fluid every 50,000 kilometres is a good recommendation, whether that would save the bearing or not. I don't know. We do a lot of Volvo differentials, rear differentials. They wear out even for people who change the fluid it's, I think sometimes it's a bit of a design defect that maybe the bearing just wasn't quite up to snuff for the job. But you know, certainly if you change the fluid more frequently, you've got a better chance of it surviving.

2008 Volvo XC70, Power Window Repairs

Mark: Hi, it's Mark from TLR. I'm here with Bernie Pawlik, Pawlik Automotive in Vancouver, BC, Canada. Vancouver's best auto service experience. 23 time winners, 23 time winners of best auto repair in Vancouver as voted by their customers. And we're talking cars. How are you doing Bernie?

Bernie: Doing very well. 

Mark: 2008 Volvo XC70 had some sort of power window problem. What was going on with this Volvo? 

Bernie: Yeah, so our client brought the vehicle to us the left rear power window. Wasn't working also the door lock as well. And there were occasional times when it would work, but most of the time it wouldn't. So that's the issue we faced. 

Mark: So what kind of testing and diagnosis process did you go through? 

Bernie: Well because of the kind of car with modern computer technology, we hooked our scan tool up and we looked to see what sort of signals we're getting from the various switches in the vehicle. And from the drivers main switch, we could see in the computer that all commands to the power windows were as they should be and what we expected, but the window wouldn't work. And there's bi-directional control. So we were able to operate some windows, but we couldn't operate the left rear window through that control. 

Mark: So digging into this now, how did you go a little bit further?  

Bernie: So what we would do in any older car, without computer system that is pull the door panel off the left rear door, start testing the wiring. Inside there's a, it's a pretty complicated setup. I mean, there's your basic power window motor and door lock actuator. Like you'll find in any car that's been built in the last 50 years, but what is more complex is there's a door module. There's a module and every door a computer sends a signal from the body control module. When it gets a signal from, whichever switches, it gets processed through that computer and that will send the signal to the motors to actuate it. So that wasn't working.

So we had to do some testing on the wiring and the area that we tested, we test for basic power and ground. All those were present, but the one area that we started focusing on us, it's called a LIN bus system. It's a computer bus system, the communication system between the computers that control a window system.

So those were the next series of tests that we did because clearly that issue wasn't getting the proper signal. From somewhere. Either by broken wire, defective module or something in that area. 

Mark: So, how do you test the LIN bus system?

Bernie: Well, we use a lab scope and I'll show you some testing. We'll just do a little picture show here. You should see a picture of a nice silver Volvo.

So this is basically on a lab scope. A lab scope is basically, it tracks time and voltage, and you can see at this point, this is a zero volts. This is 12 volts, and somewhere around little under 12 volts, maybe 11, is the highest voltage you get. And about one volt is sort of the bottom end. And this signal will switch. Back and forth in various patterns. But it's key to have these fluctuations. 

Now what we were getting when we hooked our test probe up to the LIN bus wire on the left rear module is it is basically stuck at 10 volts. It's just a solid line going across the screen. Obviously a problem. So we pulled the driver's door panel off where the door module is, and we found it, it had this signal that we're looking at here. We unplugged the other door modules to make sure there wasn't anything going on there. There was no signal coming from the LIN bus system to this door module, probably a broken wire somewhere along the lines. So that's kind of how the diagnosis goes. It's time consuming. That's basically what we found. 

Just kind of an idea here. This is a wiring diagram. I always show these because I really like people to know the complexity of what we're dealing with with a car. It's not just a matter of let's plug our scan tool in, Oh, there's the problem. You know, here it is, let's fix it. This often takes a few hours worth of dedicated time to fix these issues.

So this is just one example, but this is the left rear door module. You can see there are about 20 wires going in and out of this. Powers, grounds, signals, power to the motors, power to the power door lock. And in this one, wire that I've circled here. It says computer data lines, that's the LIN bus line.

This is where it's supposed to get that fluctuating signal, which it was not. So those was our diagnosis. So you probably wonder what did we do next? 

Mark: What do you do next, Bernie?

Bernie: So we kind of figured, at this point, you've got to kind of think, well, where would the most likely chance of a broken wire be? And it would probably be the driver's door because that gets opened and closed more times than anything. It gets the most exercise and gets the most wear. So we start pulling wiring apart part that went into the driver's door through the door jam and we found a broken wire. And here's a couple of pictures.

So the red arrow points to our broken wire here, which is part of this connector, main connector to the driver's door. And finally, one more shot again. You can see the wire broken. Yeah. So we basically repaired the wire, soldered, heat shrunk, extended it. We do whatever we need to do to make sure it's reliable and will last for another 10 15 years. And that's basically the repair done. After that everything came back to life in the rear door.

Mark: Essentially the LIN bus, that your scan tools, when you're checking things are going to point in a general direction most of the time. Without being very specific about, okay here somewhere in these miles of wiring, literally miles of wiring in the car, hidden in all kinds of cavities all over the place. There's a problem in one of these somewhere. It'll tell you perhaps which one, but it won't tell you where. Is that right? 

Bernie: Yeah, absolutely. The scan tool really is just a direction of where to go for repairs. And interestingly enough, I mean, we have a tech support team with the scan tools we have, and we will often call them or send a data file in saying, Hey, here's what's going on. Have you got some thoughts or suggestions. Because most of these things we find are first time repairs, and there's a whole team of people that we have. So when you come to us, you've got that backing of a lot of experience. You know, which is what you get at either dealership, manufacturer level on some of what we have is probably even better.

But anyway, so we sent the file off with these particular trouble codes that we obtained out of the computer and the tech rep who is helping us suggest that it probably was a module because that's almost always what goes wrong. Well, you know, if we just go, let's just change the module, we would have wasted the customer's money and been doing more diagnosis for free.

So from there it just gives us a direction to understand how the circuit works and the information, and then we can go from there. So, you know, some repairs are simple. A lot of them are not, I think it's just important to know that  when you have something that's going on in your vehicle. 

Mark: And plus part of it's experience, like being able to know that, Oh, the rear window isn't working, let's just tear the rear door apart. And then maybe we'll find it kind of the guess and by golly method of diagnosis, which you don't use. No, we don't use. Basically a more thoughtful, true problem diagnosis way of finding the actual issue. 

Bernie: Yeah. It's very important to do that and follow a structures and procedures and that's the best way to find the issue and sometimes you go, okay, well let's just start at where it's most probably a problem and which we did the driver's door and that's where it was.

I mean, we could've started tearing the wiring apart at the rear door and through the rest of the vehicle, but it's, again, it's like probabilities of where are things going to happen? You know, the other area, when we find a wiring issue on a car, we'll often ask a client, Hey, has this car been in an accident recently? Or do you know anything about an accident history? Because again, wires don't normally fail for no reason. They're pretty durable. They could last a hundred years, but sometimes there's a reason. 

Sometimes it's the way something's manufactured, but when there's something that moves, it's in a spot where something is moving. That's where a wire can often be faulty. Or if there's been a collision and you know, there's been repairs done and maybe it hasn't been done properly or, you know, we see that a lot. So it's all about asking the right questions too. 

Mark: So after the repair, everything worked fine?

Bernie: Yep. Windows good, door locks fine, everything back to normal. And so really, I mean, it was a time consuming repair and costly in that manner, but you know, no expensive parts were required. These door modules are expensive. They often require reprogramming on Volvos, which I don't know why, but they do.

You have to program the module for the door. Even if you change the driver's door switch on a Volvo, you have to reprogram the computer for the door switch on many models. So it's kind of crazy and it's not, you think why, but the way it's built.

Mark: And how are these  XC70 Volvos for reliability? 

Bernie: Well overall, I'd say pretty good. This car has got over 200,000 kilometres. It's a 2008. So what's that make it, 13 years old now, you know, that's a fair bit of mileage. One thing we did find as there was some oil leaks on the engine, which looked to be probably a major repair. If the owner takes that on. They're not severe leaks, but we have done the rear differential on this vehicle. 

You know, they're a bit of a quirky design vehicle. They're a little more expensive than average to fix, but overall, a pretty good car. I think sometimes when you give a car time to age out and you can kind of see whether it's good or not. And I think these are pretty good cars. Just expect things like the rear differential. If it hasn't been done, you'll be doing it.  

Mark: They do a lot of differentials, rear differentials for Volvos and Land Rovers. If you need some service for your Volvo in Vancouver, the guys to see are Pawlik Automotive.

2015 Dodge Ram, 5.7 L Hemi, Camshaft Repair

Mark: Hi, it's Mark from TLR. I'm here with Bernie Pawlik, Pawlik Automotive in Vancouver. Vancouver's best auto service experience. 23 time winners of best auto repair in Vancouver as voted by their customers. And we're talking cars. How are you doing Bernie? 

Bernie: Doing very well, but I just noted you've rebranded yourself since we last talked.

Mark: It's easier to say TLR, that's it.. 

Bernie: It is, sounds awesome. So yes, we're talking cars. We're talking trucks. 

Mark: Trucks. Yes. 2015 Dodge Ram Hemi that had an issue with its camshaft. What was going on with this vehicle? 

Bernie: So the vehicle came to our shop. The the owner had stated that they'd taken their vehicle to another shop and were told they needed to replace the engine. The engine out of misfire. We performed some diagnosis, did some testing and we found that was in fact the case. There was a misfire in the engine. 

 Mark: What diagnosis and testing did you actually do? 

Bernie: So you know, our basic procedures of course, to run the engine, verify the concern. We could definitely feel the engine wasn't running properly, connected some diagnostic scan tool equipment, test for codes, look at the computer data. It was pretty apparent. There was a misfire, I believe it was number three cylinder, pretty apparent. So from there we, you know, inspected the spark plugs, compression test on the engine. Compression was good.

 We inspected the fuel injectors made sure there wasn't anything else that was missed. Cause there's a number of things that could be. From there, it was basically remove the valve cover and see if the valves were opening. We know cam shafts you know, worn cam shafts are a common problem and verified the intake. The intake rocker on that cylinder was basically not moving at all or barely moving when the engine was cranked over. So problem found. From there as a matter of removing the engine, not replacing the engine but just repairing it. 

Mark: So how many kilometres are on this truck? 

Bernie: 128,000. Really not much, still a youngster. 

Mark: So I'm assuming that it's the cam shaft that's worn out and the lifters. 

Bernie: Cam and lifters, yep.

Mark: So why would it wear out so fast at this small amount of kilometrage? 

Bernie: Well, I did a little research into it because if you look at our podcast history, you'll see that we actually did one of these a couple of years ago on a Jeep 5.7 litre Hemi. And it's an exceptionally common problem on these engines.

 From what I could determine, I mean, bad maintenance is always something that I think can be an issue. And we look at some pictures in a minute, I'll show you just kind of an example of it. It's not that we found the oil was particularly bad on this engine. They may have done okay maintenance on it, but the service intervals are pretty long. The recommended Dodge interval was like 13,000 kilometres. It's synthetic oil, but you know, my mind I'm just way too long to go. The other feedback I got is it's possible that just idling these engines, the camshafts just don't get quite enough lubrication that the cam and lifter area, the cam are lubricated by splash  from the crank case.

And it's possible that, you know, it just doesn't get quite enough lubrication when the engines idling is not enough oil splashing around. So either way, whatever happens, you know, that these items do tend to fail. And now it could be bad materials too. It's kind of hard to know, but mean, that does happen from time to time to that where they just don't make the material is sufficient. So I guess what I'm saying, I don't really have a super definitive answer, but you know, obviously changing your oil on a regular basis, sooner than recommended is a good idea. 

So pictures. There's the side of our truck Ram 2,500 heavy duty 5.7 litre, very common engine package in this vehicle.

2015 Dodge Ram, 5.7 L Hemi, Camshaft Repair

And let's have a look at a few items here. So speaking of bad maintenance. This is the air filter we pulled out of this vehicle. I don't have a new sample, but it's basically supposed to be absolutely snow white and colour. And this thing is, is, is among the blackest dirtiest air filters we've ever seen. Now, a bad air filter isn't likely going to cause the cam to wear out, but is an indication of how well was this vehicle maintained. And I'd say that there was definitely some missing maintenance along the way. 

2015 Dodge Ram, 5.7 L Hemi, Camshaft Repair
2015 Dodge Ram, 5.7 L Hemi, Camshaft Repair

Okay. The cam shaft. There's a couple of lobes with some, this is some bad wear, but this, this isn't that really bad lobe. But a number of them were badly worn. Where's our really bad one, there's the bad one. I mean that that lobe is completely worn off. You can see it's kind of an egg shaped item. Well, the egginess has completely gone here and what happens is the lifter, these are roller lifters, they have like a roller bearing.

2015 Dodge Ram, 5.7 L Hemi, Camshaft Repair
2015 Dodge Ram, 5.7 L Hemi, Camshaft Repair

They roll on the cam shaft for low friction, but over time, the roller bearings fail or something happens and it just ends up grinding the cam lobe down. We'll have a look at the cam lifters. Here we go. There's the lifters. There's a used lifter, but this one is in pretty good shape.

2015 Dodge Ram, 5.7 L Hemi, Camshaft Repair

This is the bad one from that cam lobe. Now you can see how the metal is just ground down, completely here. And if you look here, you see how much higher this roller sits. This was completely seized, but inside there's a little roller bearing. So it rolls and as I say it's a very low friction item, but all it takes is that roller bearing to skip a few times or wear out and then it'll disintegrate and start, you know, riding on the cam shaft in a funny way. Grinding it up and it just becomes a disaster from there. 

2015 Dodge Ram, 5.7 L Hemi, Camshaft Repair

There's the new camshaft and you can see the lobes are nicely shaped. Everything's clean. This area here, this engine has variable valve timing, it's something they introduced I believe it's around the 2009 model year. So these oil passage ways are part of the variable valve timing system. Now because it's only on single cam shaft, of course they can only vary the valve timing for the intake and exhaust all at the same time.

Whereas if you have overhead cams or individual cams on each like exhausted intake, there's much more flexibility and adjustment. But the nice thing about this type of pushrod engine is it's simpler and there's less moving parts. I think that kind of covers it. I mean, a couple of views here.

2015 Dodge Ram, 5.7 L Hemi, Camshaft Repair
2015 Dodge Ram, 5.7 L Hemi, Camshaft Repair

This is the engine. The engine must be removed to do this work so the cylinder heads have to come off to access the lifters. And so this is the engine being re-installed and another view of the engine with the intake on and assembled, getting close to running time. So that's most of our pictures, I've got a couple more to share as we talk a little further.

So further items that were damaged. Last time we did this, it was basically, you know, the cam and lifters were replaced. On this particular engine, we ran into a couple of other things.

2015 Dodge Ram, 5.7 L Hemi, Camshaft Repair
2015 Dodge Ram, 5.7 L Hemi, Camshaft Repair

The rocker arms only on the intake side had been pounded out pretty badly. This is where the rocker arm contacts the top of the valve.

And here's an intake valve. You can see this top is supposed to be completely smooth and shiny, and you can see it's very pounded out and damaged. So all the intake valves had to be replaced, along with the valve springs had some wear. They were basically softer than specification and all the intake rockers. Exhaust valves surprisingly were all in good shape, but for some reason the intakes took the brunt of the wear. I think that concludes our slideshow.

Mark: Okay. So this is pretty catastrophic failure. Was it, this is a I'm throwing you a curve, would it have been cheaper to just get a used engine and put it in rather than doing this repair? 

Bernie: Well, it's an excellent question because we do a lot of used engines and I'd say no. A) it wouldn't have been any cheaper. I mean, the cost would probably have been the same, but the thing where they used engine is you're just buying an engine that's probably got the same problem that's going to happen again. So where used engines are good is where the failure is maybe someone just didn't change their oil enough, or they let the timing chain rattled too long and it broke. So that's it, but the engine is generally quite sound. So that's where used engine's good.  

I've had a few customers with Toyota's where they just, for some reason haven't changed their oil in the engine blows up, but like the engines themselves are, you've never have a problem with one. So that's a good used engine, but on this particular car, because of the problem, if you've got a used engine, you'd probably want to change the cam and lifters anyways, before you even put it in. So that's a great question, but yeah, it definitely not the best way to go. 

Would it be worthwhile to rebuild the engine while it doesn't really make any sense? Cause the rest of the engine is really quite sound like the pistons. The bottom end of these engines is really good and it's really pretty trouble-free. So you know, just doing the cam and lifters and fixing the valves and heads, it'll go for a long time. With good maintenance.

Mark: So camshaft and lift your issue, is this common on Hemi's? 

Bernie: Very common. If you Google it, you'll see it just, it's a huge, huge issue on this 5.7 litre engine. And it seems like it happens more on the 2009 and newer, and you know why that is. Not quite sure, but they introduced a few features on, on the 2009 and newer like variable valve timing.

And that can affect the way the oil flows through the engine. Also they have multiple cylinder displacement. So it can actually kill certain cylinders while you're driving down the highway when you don't need the heavy load to improve fuel economy. So these may have an effect on how the engine is oiled, because that's controlled through the oil system and the engine.

So why it's a failure? It's hard to know exactly, but again, I would just say change your oil regularly, like more frequently than recommended. And don't ever miss an oil change because it can be as simple as just missing one oil change can make a difference or just extending it a little too long.

Mark: Was this an issue on the older, like the Hemi has been around since the fifties, it's like 70 year old engine basically in design. Was this a problem in through the 50s, 60s, 70s? 

Bernie: Not that I know of course that's getting way back there. So the newer generation of Hemi's where I think they reintroduced it around 2002 and it hasn't really been a problem in those, but it is on these 09 and newers. And you know, there's a few other displacements of Hemi's to the 6.4 litre I think, I believe the Hellcat's is 6.2. I don't know if those have any problems, cause that's an extremely rare engine, but 6.4s do apparently have problems. We haven't seen one yet. It's not the most common engine either, but apparently they do have problems with the cams too. So,  you know, it's basically the same engine, just bored and stroked differently.

Mark: So would a diesel, I hate to ask this, would a diesel engine be a better more reliable option for this Dodge Ram truck heavy duty Ram truck? 

Bernie: Well, it's a good question because and my answer is it depends on what your application for the diesel is. If hauling some heavy loads, the diesel might be a better option. But if it's just kind of an around town kind of moderate load truck. I'd say probably not, because you can end up spending the kind of money this repair job costs on a diesel pretty easily with if the emission equipment goes bad or something like that. 

So well, you know, the operating cost of the diesel is lower. And I guess the other thing too is to buy the diesel truck costs a lot more money in the first place. So if you're hauling heavy loads, the diesel is probably a better way to go. But you know, on a lighter duty application the gas is probably still a better way to go. 

Mark: So there you go. If your Hemi is having some issues in Vancouver. Oh, here's another question. I forgot. Let me interrupt myself, Bernie. Sure we would you hear this with that cam lobe wearing out like that and scraping so bad? Would you actually hear something?

Bernie:  Well, yeah. So, you know, what's interesting about this particular issue is that this engine wasn't really tapping or clicking, like we would normally hear. I don't know why, because I last Jeep that we did the podcast on the reason we actually repaired that one wasn't because the engine was running badly. Cause there was a ticking sound in the engine. So yes, a ticking sound is the first issue it's like, you know, now there's multiple things that can cause that, but on this engine, you can be pretty sure if you've got a ticking sound, it's probably a failed lifter or a cam shaft.

And that other Jeep we did, I mean, the cam lobe was worn, but not particularly as bad as this and the lifter again had had collapsed, but the wear it wasn't as severe as this. So it was surprising that there wasn't a ticking sound, but normally yes, you would hear a ticking sound. And if you do hear that, that's probably the time to get it repaired before, you know, this engine probably went way too long and then all the valves have got pounded out. You know, that's not always a repair that's needed, but in this case it was. 

Mark: So if your Hemi's ticking, get it in for some service. If you're in Vancouver, the guys to see are Pawlik Automotive.

2003 Honda Accord, Spark Plugs and Ignition Coils

Mark: It's Mark from Top Local. I'm here with Bernie Pawlik, Pawlik Automotive in Vancouver. Vancouver's best auto service experience. 23 time winners of best auto repair in Vancouver as voted by their customers. We're talking cars. How are you doing Bernie? 

Bernie: Doing well? 

Mark: So 2003 Honda Accord had a problem what was going on with this vehicle? 

Bernie: Yeah, so the client brought it in, it was due for a maintenance service and she had also noted that the engine was running rough under certain conditions. 

Mark: So how do you go ahead to proceed and test and diagnose what was going on? What was the actual problem? 

Bernie: Yeah, so we road test the vehicle and we could confirm under, you know, a bit of a load condition, the engine was running roughly, like misfiring. And that's the first step. So we got our diagnostic scan tool, that'll help us get in the direction of which cylinder the issue might be occurring in. If there's a misfire.

So we look at the data on the scan tool. We scan for codes and found, there's actually a code for misfire in every cylinder. So when there's a code, usually it comes up as P something. And so P03O1 , for instance means cylinder number one, misfire.

And it's interesting when they use diagnostic trouble codes or set up certain  codes, mean certain things like a 300 series code is an engine misfire code. A 400 series is an emission systems code. So it's kinda well-organized but anyways, there's a number of codes for a cylinder misfires, all of them in fact, not just one. So that made for some interesting next level testing. 

Mark: What exactly is a misfire and how do you determine what's causing said misfire? 

Bernie: When an internal combustion engine is running and you could have anything from I mean, I think about in cars, what we found is, you know, 3 cylinders kind of the minimum that you'll find and 12 is usually the maximum. And any of those cylinders every time they go through their cycle, they're supposed to fire as a spark and it's supposed to work. You know, it's supposed to fire a good combustion cycle and if it doesn't, the vehicle computer through a, usually a crankshaft position sensor, the speed of rotation, will figure out, Hey, that cylinder didn't fire properly. You can also feel it usually. 

Sometimes you'll get misfire codes where you don't feel any issue, which can sometimes be a sensor problem or something else, but normally you'll feel a roughness in the engine. It just isn't performing properly. It shakes or shutters, something happens. 

So the misfire is basically a combustion event that did not occur. And there are a number of reasons for it. It can be anything from like bad compression of the cylinder, or it may be a valve is burnt. It can be a spark plug that isn't firing and ignition oil, computer problem, fuelling objector intake leak. There's a number of things. And misfires can happen at low speeds or high speeds. So there's a number of causes. So I think he had a two-part question. What's a misfire. And what was the other question, Mark? 

Mark: How do you determine what's causing it? 

Bernie: Yeah, so how do we determine? So we basically go through a tree of items to look at, first of all, and a lot of is based on our own experience.  I've worked on cars for my whole adult life. I can usually tell by driving along, yeah. It feels like an ignition misfire. It feels like the spark plug somehow just didn't fire that spark. There's just a certain feel to it. Which can, it's not a hundred percent accurate, but a lot of times I find it could be 95% accurate, but there are things we can test. And usually the easiest area to start with is ignition system. 

This has an individual ignition coil per spark plug. It's a six cylinder engine, so we can transfer spark ignition coils around this specific cylinder. What we did is clear the codes and we're able to narrow it down to a couple of cylinders that it seemed to be more common causes.

So we swapped ignition coils around between the different cylinders and the issue followed those ignition coils. So then we know that coil is the problem. Also, when we removed a spark plug, you can see they were pretty old. So again, that was something we suggested to do as a repair as well.

Mark: So I don't imagine it's, because they're fairly accessible most of the time. It's not that difficult to job. Replacing spark plugs and ignition coils. 

Bernie: On this Honda Accord is actually a pretty straightforward job. We're lucky here because a lot of V6 engines have an intake plenum that hangs out over the back of the engine. So the rear cylinder bank is very hard to access the spark plugs and coils. And you often have to remove the upper intake manifold to take those apart. So it can be quite a bit more time consuming. 

On a Honda they've nicely put the intake plenum square over the centre of the sort of V of the engine. So it makes for a pretty straightforward replacement. And we have pictures here. We can actually look at some stuff. Let's have a look at some pictures. 

So there's our, there's our 2003 Accord. It's a 18 year old car, but still in pretty nice shape where you can see a little scuff on the bumper here. If you look close enough, but still nice and shiny and  in good condition. 

2003 Honda Accord, Spark Plugs and Ignition Coils

There's the front cylinder bank of the engine. So again, it's a V6 engine. There's three ignition coils. The rear is kind of like, looks like the same. And fortunately as say you can access it.

The other thing about this car too, is it has more of a longer hood than you find a newer cars that can often make it difficult to access the coils in the rear as well. But fortunately, on this car, it's not too difficult. 

And there we have the old ignition coil and spark plug, you can see the spark plug, there's a fair bit of corrosion above the, usually you get, you find these after awhile, there's probably a tiny little bit of combustion gas leaks out through the porcelain of the spark plug, not a big issue, but it kind of indicates it's been installed for awhile. These are probably original spark plugs. Hard to be a hundred percent sure. 

And there's one of the old coils again, you can see a bit of corrosion that just kind of common on coils, but you know, inside they're magnetic windings and things that just tend to wear out or they could be cracks that can develop down this tube here, which could cause spark to leak out into the the surrounding the metal of the valve cover. There's our picture show. 

Mark: So why not just narrow it down to those two coils that you found were bad and change all the plugs, but just those two coils? 

Bernie: Well, that's certainly a possibility. And one thing I will say is when the vehicle was brought in and had a misfire in all cylinders. So that doesn't necessarily mean that they're all bad, but they could have all been bad at some point in time, or sometimes, you know, one or two cylinders will cause all of them to misfire.

Sometimes just clear the codes and see what reoccurs, what's happening right now. But anyways, to answer your question, you know, it's a mathematical thing sometimes. How much did the coils cost? How much time does it take to diagnose the issue? How old are they? If two have failed and the vehicles got 165,000 kilometres, how likely is it that the other four are on their way out? If two or three have failed now or getting weak. 

And then the question is if you can narrow it down to those two specific coils and we do have other ways to test besides swapping coils. We can hook it up to a lab scope. We can actually look at the firing patterns of the coils and see how they're firing. But besides that you know what happens in a month or two, and we've had this happen where we've had a vehicle, say it's a four cylinder, easy to change a coil. Hey, just change one. We found one that's bad then. A month later, the customer's back, Hey, the engine's running rough. Then you have to redo the diagnosis. There's a cost there. 

So I think it's better, we do them all. You know, we have a, usually a two-year warranty on these items. So customer has a two year warranty it's done, you know, finished anything happens, say a coil goes bad. They're still covered for two years.

So you know, whereas if we do just one or two and then, Oh, that one, you know, there's another one that's bad, there's more diagnostic fees and more testing. And it just makes sense.

Now the only time it may not, if you have a vehicle with a very expensive coil, I used to own a Subaru with an H six engine, very expensive for the coils in this engine, because it's not a common engine. So. I had one that failed. I just replaced one because it was so expensive to change the coil to do all six would have been a couple of thousand dollars in parts. Kind of ridiculous. So you just gotta do the math and figure it out, but usually it makes sense to change them all once the car gets old. 

Mark: And that's based on, like you said, pretty much your entire adult life working on cars and having gone through every other possible way of doing this to try and save money for people and finding that the best way is sometimes the easiest way. 

Bernie: Yeah. And when you think of it from a maintenance perspective, again, you know, I love aircraft maintenance because they fixed stuff preventatively because they can't really afford an aircraft engine to fail while you're mid flight.

So you're thinking, well, why would you want your car to do the same thing? Yes, it does cost a little more money to do that, but it makes your driving experience overall a whole lot better and more enjoyable. More peace of mind. You know, this is time to change the ignition coils. They've run their lifespan. This is time to do them. 

Mark: Basically save your frustration for all the other parts of your life. 

Bernie: That's right. Exactly. Exactly. But if your car runs well, that part's easy. 

Mark: You mentioned this vehicle has 165,000 kilometres. Was there any other service due at this time?

Bernie: Well, there's a couple of things. One thing we did do, and this isn't in the Honda schedule, we did a motor vac fuel injection cleaning, which is something we recommend every two, three, four years on a vehicle, depending on how much you drive it. So we did that during this service, which made a lot of sense, considering the engine had been misfiring and we'd never done one on this particular vehicle. This person's owned the car for a few years. So we did that. 

But the other you know, schedule maintenance item is the timing belt. This engine does have a timing belt that's due about I think 165 or 168,000 kilometres. So we didn't do it this service. But we will be doing it in the near future. So that's kind of the big service item on a Honda and actually spark plugs were actually due at this particular time. So it's a good time to do it all. So timing belt coming up next and that's kind of the major Honda item. 

Mark: And how are these, this is an 18 year old car? How are these age of Accords for reliability? 

Bernie: Yeah, that's a really good car. Now it's funny talking about reliability for a car this old, but at least we've had 18 years of experience to see what kind of a car it is. And the automatic transmissions have been a problem on Honda's of this sort of earlier, early 2000 generation. And I'm not sure if this one's ever had the transmission replaced, it works fine at this point, but that's definitely a problem that's happening. And often they happen, you know, fairly early on in the life of the car, in the five to 10 year old range of the car. So I consider that to be kind of a bit of a problem, you know, for reliability. But other than that, they're good cars. I mean, there's the expense of the timing belt, which a lot of engines don't have, but at least that's a predictable expense.

Whereas say a timing chain failure is a non predicted expense and a lot more money. So overall, you know, I think they're excellent cars. You know, do you want to buy an 18 year old car at this point? I mean, if you're looking for an older car, that's probably well priced. They're still reliable if you can get one that's well-maintained.

2006 Volvo XC90 – Catalytic Converter

Mark: Hi, it's Mark from TLR. I'm here with my good friend, Bernie Pawlik, Pawlik Automotive in Vancouver. Vancouver's best auto service experience. 23 times. I might even have some news about that. 23 time winners of best auto repair in Vancouver as voted by their customers. We're talking cars. How are you doing Bernie?

Bernie: Doing well. 

Mark: So 2006 Volvo XC90 had a catalytic converter problem. What was going on with this  vehicle? 

Bernie: Yeah, so the vehicle came to our shop. Customer had a few concerns. One was a rattling sound in the exhaust system. So yeah, that's basically the bulk of it, but that was the biggest concern.

Mark: So what kind of diagnosis inspections did you do? 

Bernie: Well, because this client was new to us and they had a number of concerns besides the rattling and exhaust. We did a comprehensive inspection. So it's a full vehicle inspection and then looked at the exhaust. We could hear the rattling sound.

We basically do a visual inspection to see if there's anything loose, you know, wiggle things around, sometimes we'll use rubber hammers on things. Variety of things sometimes just running it with one person in the vehicle, getting the right speed or, you know, until cause of vibration, this is what we do. We have different listening equipment, whatever it takes. And what we found is that the catalytic converter had a rattle inside, internally. 

Mark: So how does, leaving aside the fact that you're using rubber hammers, which my wife likes to use on me. How does the catalytic converter rattle internally?

Bernie: So what happens is the way catalytic converter, it's basically got a shell body. We'll look at a picture in a minute and inside of it, there's this it's like a sort of metal honeycomb grid, it's all welded together, very compact. And usually there's some kind of fireproof lining that goes around that.

And eventually over the years as cars, you know, it's 15 years old, it's got a fair number of kilometres on it. Things will rattle around. Sometimes people will actually hit them depending on where it's located. They might bottom out and hit it. That wasn't the case with this vehicle. But sometimes if you were to hit the converter, you know, hard to say on a rock or something, or go over something that could cause it to come loose. Sometimes just over time, the metal expand and contract, expand and contract over the years, happens a lot. You know, eventually things will kind of get loose and start to shift around inside. 

Mark: So, how does that affect the performance of the catalyst in the converter? 

Bernie: Well, it eventually will degrade the performance because the exhaust, to be effective of course the exhaust has to flow through the substrate with all the precious metals causing a chemical reactions with the exhaust.

And so any exhaustive bypasses that, which it can eventually, especially if the rattle gets severe, will definitely degrade the performance of the converter. And you'll know that because the check engine light will come on, at least on a converter of this age, because it's anything after 1996, the converter is monitored for its efficiency. So that hadn't happened yet on this vehicle, but it certainly would at some point. 

Mark: So, are there other reasons, other than someone's stolen it, that catalytic converters require replacement? 

Bernie: Well, it's funny you talked about the stolen one, cause I was going to talk about that, but let me just share a picture for a second while we're talking about that.

There's our 2006 XC90. Still in good shape for a 15 year old car. 

2006 Volvo XC90 - Catalytic Converter
2006 Volvo XC90 - Catalytic Converter

And there's the catalytic converter assembly itself. So you mentioned stolen. So these things, on this particular vehicle, this part of the flange just sits against the turbocharger. There's a flexible pipe. And this is actually a failure item on a lot of exhaust systems will cause loud exhaust, and we can usually replace these. We can buy the flex couplings and weld a new one in. 

There's the catalytic converter right there. That's the body of the cat. And inside is that substrate. This one is located under the vehicle and people will slide under there or jack it up or whatever means they have with a SAWZALL, like a portable reciprocating saw. It's nice and easy to do nowadays because there's so many battery options available, and they'll just slice it out and you'll get out one morning, start your car. And it's super loud and catalytic converter's gone. 

But other reasons for failure is basically, you know, they're not supposed to ever wear out, but they will wear out eventually. And it's just when, who knows. I mean, I had a 2001 suburban I sold last year, had almost 400,000 Ks. Cats were still original and working fine. As I say, you, you just don't know how long they'll last. You know, a lot of times, they might get hit if they're underneath the car or the substrate will work loose and rattle. So those are really the reasons they'll need replacement.

Oh, we'll give another thing. They can get plugged. You know, if you have an engine that's misfiring, often the check engine light will blink. That's something you really need to fix. A check engine light that's on solid is fix it soon. A check engine light is blinking. That's a serious concern.

It indicates a catalyst damaging misfire. What happens is, an engine misfires it dumps a lot of raw gasoline down into the cat. It gets very hot and it will actually melt the substrate. So that's another reason for replacing these. They'll get plugged, you'll lose power. And that needs to be repaired.

Mark: So the chemical reaction that's taking place in there with the platinum, and I don't know what else is in there. 

 Bernie: Palladium rhodium platinum. Those are usually the materials. 

Mark: I was going to guess that. Okay. Sorry. They react with the exhaust gases and pull the pollutants out of the air, basically. So the exhaust is cleaner coming out of the tailpipe?

Bernie: Yeah, essentially that's what they do. They take any excess hydrocarbons, carbon monoxide and oxides of nitrogen. They basically convert that into CO2 and water. That's basically the ideal reaction.

So we're basically pumping more CO2 into the air. But less harmful noxious type of pollutants. You know, that cause other diseases. Like carbon dioxide and oxides of nitrogen are particularly bad hydrocarbons. 

Mark: We're getting rid of the kill you now stuff. But increasing the kill you later stuff.

Bernie: Exactly. Exactly. And we're doing a really good job of that because it's amazing how little of those other pollutants really come out of a tailpipe of a car that's been built in the last 20 years. 

Mark: So what kind of replacement options are available for this catalytic converter on a Volvo?

Bernie: Well, there's a couple. There's an aftermarket pipe and catalyst assembly. We sometimes will do custom work where we'll actually weld in a really high quality universal converter or you can buy a new converter from the dealer. We've talked to the customer with different options.

In this case, we actually went with the dealer converter. This is  actually an OEM Volvo catalytic converter. So the OEM converters cost a lot more money generally than the aftermarkets, but they are much better. They have a full catalyst load in them. And which is why they cost a lot more money.

You're not just paying for the name because it's from Volvo or from wherever you're buying. It actually is the best quality unit you can buy. But often the price can just be enormously expensive, but in this case, it was a lot more, probably about $900 more to use this dealer converter over an aftermarket. But clearly this will last for, if these people keep this car for another 15 years, which is doubtful ,it'll last for 15 years. Unless you have a misfire problem which can wreck the catalytic converter pretty fast. But as long as you keep the car in good running shape, it'll last definitely for the life of the vehicle if these people will keep it for. 

Mark: So is it possible to buy a used converter? And would that be a good idea? 

Bernie: Well used is a bit dicey. You know, I've actually seen auto wreckers that won't sell catalytic converters. I remember there's one said, you know, federal law won't allow us to sell one, which seems kind of ridiculous. And that could be an American thing. A company that used to be American company that used to sell a lot of used parts here, but we have bought used converters. We rarely ever do that because it's kind of risky. You don't know how long it's going to last for, and you don't know if it's going to be any good until you actually install it in the vehicle. 

I mean, we can bang with a hammer and make sure it's not rattling, but you don't know whether it's plugged or whether the efficiency is low until you actually install it. So it's a very risky item to do. You know, if you do it and it doesn't work, then you've got a lot of labor to pull it back out again, to fix it.

Mark: And probably now with the price of palladium, rhodium, platinum, that why people are stealing catalytic converters. A lot of wreckers aren't going to be selling the converter because it can get more money by recycling the precious metals. 

Bernie: Well, no, I would say that you could still, it's still worth more money as an intact item. I mean, if you consider a lot of auto wreckers, some of them have a, there's sort of a policy of selling it for half the price of new.

So I mean, this converter could, you know, they could potentially sell this pipe for six or 700 bucks or more even if someone would pay that for it. But then, you know, that's almost approaching the price of an aftermarket new converter. So you think, well, which way is worth it.

And if it only has a 90 day warranty, it's kind of hard to legitimize, but  I mean as a piece of scrap metal, that catalytic converter is probably worth a hundred bucks.  

Mark: There's gotta be an easy way to make a living. So how many kilometres run this vehicle? 

Bernie: Yeah, so this vehicle had about 277,000 Ks actually. So it was quite up there. Ran really nice.

Mark: So how are XC90s overall and how are they for reliability? 

Bernie: Pretty good vehicles. You know, we've talked a lot about Volvos over the years. Certain quirks rear differentials wear out. They do have some transmission issues and some model years, the drive belt system on some of these is rather strange and expensive to fix, but overall I'd say they're pretty good.

And I think sometimes you have evaluate a car, you know, it's 277,000 kilometres it runs great. You know, needed a few thousand dollars worth of repairs, including this converter, but now the car is in good shape and it'll go for quite a while, I would say without any further issues. So, you know, overall a good car, but you will spend more money on these to fix them, but it is a, you know, kind of a top level European SUV vehicle. Good safety and comfort, creature comfort. So there's more to go wrong, a little more expensive to fix, but definitely a decent vehicle. And I think this one's proven itself over time with the mileage on it that it's a pretty good car.

2014 Honda Acura RDX B-Service

Mark: Hi, it's Mark from TLR. I'm here with Bernie Pawlik Pawlik Automotive in Vancouver. Vancouver's best auto service experience. 23 time winners of best auto repair in Vancouver as voted by their customers. We're talking cars. How are you doing Bernie? 

Bernie: Doing well.

Mark: So 2014 Acura RDX is today's victim. What was going on with this vehicle?

Bernie: This vehicle came to our shop for a maintenance service. It was due for a B service. So that's exactly what we did. 

Mark: So what's involved in a B service?

Bernie: So B service is an oil and filter change, plus a full vehicle front to back inspection. Wheels off. Tire rotation if needed and doable, which it is on this vehicle. It's only not doable if you have vehicle with different sized tires, front and rear. So that's basically it. We do a full inspection, one of our awesome digital comprehensive inspections and and the oil service.

And we can get straight into pictures right now because we can actually go over some of the details of our service, because it's pretty awesome. 

So there's the RDX. Very practical little compact SUV I think. And very reliable also. There's our V6 motor peppy and powerful also, you know, which is a good feature to have. The earlier versions of this at a four cylinder turbo, which actually worked really well too. But I kind of liked this V6 engine a little better.

 So the inspection, so we have a digital inspection that we do and breaks everything down. So this is what you would get as a client of ours. This is the inspection that you would see that we either send you a link by text or by email. Lists that 94 items are okay, 10 items of suggested services, which are, you know, things that kind of need to be done, but could be done at a later time. And then two items that should be done right now. And one is a third brake light, which is a bulb, well probably a bulb. And then the other we found when we tested the alternator, that there was a low output and a blown diode.

So, this view is a little small right here. I should've got a blow up picture of it, but this is actually a view of our test screen and actually indicates right from the tester that the diode is blown. We send really good information out with these inspections.

So we drill down a little further. We can look at a couple of the suggested items. So there's the service due light was on which we've reset. The wiper blades are smudgy. The transmission fluid was due by mileage. Again, we like to look at vehicle history but the technician recommended, check the vehicle history, sure enough it was actually in fact due. Does that make it a red? Well, it's not really mission critical to do it, but it's kind of important to deal with it. A couple of the other orange items, the sway bar links had some slight play in the rear. There's a photograph again, which we include, and these can be clicked on to enlarge. So you can look at them a little closely. And then there was a very slight oil leak from the engine or transmission area. So again, we'd recommended a diagnostic on that. It wasn't severe, but just something to keep in mind. 

 And then some of the good items and these are things that we also do. So we measure the brake pads. There are numbers here. Seven millimetres in the front brakes. We measure the brake rotors, inspect the calipers and other brake components. On the rear there's five millimetres. There's a measurement for the rotors. Tires we measure the tires, adjust the pressure. So these are all noted. And this is everything you get on the inspection. There's are our picture show for the day. 

Mark: So was there any problem with driving a car with a bad alternator? 

Bernie: Well, yeah, so of course, how the procedure goes is we present the inspection to the client and estimate out the major items and maintenance items. And from there they'll make a decision. Now the owner decided, you know what, I don't want to fix the alternator. It is pretty expensive to repair on this vehicle. It wasn't that it wasn't functioning. It just that it wasn't functioning properly. So the answer is yes, it should have been done. I'll say that I think he should have done it, but it's not my money to spend. Their logic was, you know what, if the battery goes dead, we'll just tow it in. So that is one thing that happens if the alternative is severely bad, of course your battery won't charge it and you won't get far. 

But with a blown diode, you're kind of getting two thirds of the amount of output. The risky thing is that it can send strange voltage spikes through your vehicle. And sometimes you'll, you know, the engine will either not run properly. Like it'll kinda run funny or lights might flicker or something. None of that was happening on this vehicle. So it wasn't a big issue in that case, but nonetheless, you know, it's something that should have been done.

However they did choose to do some of the maintenance items. The brake fluid you know, we'd recommended flushing. They fixed the bulb of course, which is good and inexpensive. And we did the transmission service, which was due also. 

Mark: So this vehicle's got 90, 90, 96,000 kilometres. Isn't this a major service interval on many vehicles? 

Bernie: Well, yeah, and especially for Japanese vehicles, 96,000 kilometres used to be the major service interval where you do the timing belt and spark plugs. These were the things that were kind of due. Usually transmission service. Sometimes, you know, again, we're going back a couple of decades where the CV boots, usually the material they were made out of, they were starting to crack and it was like a good idea to replace the outer CV boots.

You know, so it ended up being a pretty major service and you know, pretty costly, but, you know, once you get it done, of course, then you're good for another 96,000 Ks. This vehicle, not the same. The Honda has gone with it. They have the maintenance reminder that comes on on the dash and reminds you when you're due for service.

And I have to say that I really like their system. I find that Honda they're, you know, when their maintenance reminder comes on telling you your oil needs to be changed, it kind of comes on, I think the right time, it's not too late. Well, to me the right time is when it's not too late. When the oil is just hideously dirty, like you find on a lot of European cars that they come on, you can smell the oil, it's a little old, it looks a bit old, but not hideous. And I think that's really the time you want to do it. So you're not causing any damage to the vehicle. 

And then of course, they're pretty sophisticated on the Acura. There'll be like an A1 or an A2, and the letters mean different things. So for instance, like this vehicle has a timing belt and it is due to be replaced at a certain point, but actually a warning light will come on and it'll say when a service four comes on, that'll be the time to do the timing belt. So I mean, normally the timing belt interval on these engines is usually before they had this electronic alert was usually around 168 K. So I would expect it would come on around then, but it might come on sooner if you don't drive a lot. So it'll take those factors into play. Also, you know, when you look at the maintenance schedule, if you do actually tow a lot with this vehicle, which most people don't do, the timing belt replacement interval is actually a hundred thousand kilometres.

 But again, that's a severe use that most people won't do, but it's important to look at those kinds of details because the last thing you want is to break a timing belt. That makes for very expensive engine repair. 

Mark: And how are Acura RDXs for reliability.

Bernie: Yeah, really good vehicle. It's a Honda product, very reliable. Can't say much bad about them. You know, they need a few repairs here and there. I mean the alternators, one thing we have repaired on a number of these cars and also this thing did have a little clunk in the rear that I suspect might be the rear struts that are going because that is an issue also. But overall, a very reliable vehicle. Good value for sure.

2012 F150 Heater Hose Repair

Mark: Hi, it's Mark from Top Local. I'm here with Bernie Pawlik, Pawlik Automotive in Vancouver. Vancouver's best auto service experience. 23 time winners of best auto repair in Vancouver as voted by their customers. We're talking cars or trucks in this case. How are you doing Bernie? 

Bernie: Doing well? 

Mark: So 2012 Ford F150 had a heater problem. What was going on with this vehicle? 

Bernie: Yeah. So the owner was complaining. There was no heat in the vehicle. And of course it's winter time in Vancouver and it's been a cold snap. So heat is very welcome. And yeah, there was no heat blowing in the cabin of the vehicle. 

Mark: So what, how do you test and diagnose that once it, once the vehicle's in the shop?

Bernie: Oh, it was a few things. I mean, the first thing we did was sit in the vehicle and test the heater controls on the dash and see how things were operating and everything seemed to be in good order. So our next step was to look under the hood and see, you know, check the coolant level. And we found the coolant level in the overflow tank was down a bit, not empty, but down below the full level.

And did a little further testing, did a cooling system pressure test because the level is down and found a leak from one of the heater hose connections, right at the heater core. So figured just that little lower level of coolant was enough to cause the heat not to work. And that's not an uncommon issue.

If you have a vehicle where your heat's not working, checking your coolant level is definitely a good first thing to do. I was surprised that this didn't have a warning light on the dash because I would assume most of these vehicles of this vintage and being a platinum model as well, should have had a warning light, but it may be that the level was not quite low enough, or it might be that this vehicle isn't equipped. I should probably know that doing this podcast, but I don't. 

So if you have a Ford F-150, check your owner's manual and see if that actually has a warning light to that kind of thing. For low coolant level, I for low coolant level. Yeah. That's an important thing to heat. And, you know, had that light been on the first thing, we probably would have done those, pop the hood and looked at the cooling level, but you know, we just take things in sequence.

Mark: So how sensitive, like coolant levels dropping. Is there any normal reason in regular use that that would just go down or is there always some sort of problem that's causing that? 

Bernie: Well, always a problem. Unless you have like a 1960s vehicle that doesn't have a contained overflow tank cooling system, because those will actually blow a bit of coolant out as the engine warms up and the level will sometimes drop. But yeah, coolant levels should never go down. So it'll go up and down depending on temperature, but it'll always stay between, you know, a low level and a high level. So if it's actually disappearing, you've got a leak somewhere.

Mark: So what repair did you actually end up doing? 

Bernie: Yeah, so we ended up replacing one of the heater hoses. There's a connector and I'll just get into some pictures right now. So there's our F150, it's a platinum edition.  This is like a top end model. Nice wheels, tires, you know, fancy interior though, the whole nine yards. It's a nice pickup truck.

This is the hose that we replaced. So pretty fancy hose. There's a connector on this end here. This is where the leak was. It's a quick connect connector. And this is a closeup view of the connector. There's not much to see in terms of anything being bad, but there's an O-ring seal inside there that fits onto a special fitting on the heater core and clips in, and it's held in by clips.

So really easy to assemble and disassemble. Actually, you know, once it gets old, sometimes it can be a bit of a pain. Here's a view of the engine compartment. And that heater hose is just over here where I'm circling my mouse pointer. So it's at the back. There's two heater hoses. The other one was fine. We retested it after a repair and found no further leaks coming from that area.

So this hose runs way underneath here and around. It makes a couple of connections and connects to the bottom of the overflow tank.

Mark: So you mentioned that's a fancy looking hose. So the days of just extra hose, a red, rubber hose, basically from the firewall to the, to wherever, to your radiator. Are different because of how cramped the engine space is. Is that basically why? 

Bernie: Yeah, I'd say that's pretty much it. We still have bulk heater hose in our shop and we do use it from time to time, but it sells less and less frequently because you know, most heater hoses now are all molded with special connectors.

So some of it is a cramped engine compartment for sure. But the second part is it's manufacturing it's I would say it's a lot easier to have a hose connected up to an engine that has a clip on it. And as it goes down the assembly line, I don't know if it's a human being or a machine, but you just go bing clip, and it's done, as opposed to having a clamp where you need a plier to pinch it, or you need a screwdriver or something to turn the screw.

So I'll actually just go back to this picture, cause it's kind of interesting conversation. You can see this hose here, does have a pinch clamp, but this is attached to the engine. And this one, it goes to the overflow bottle. So when this engine would come down the assembly line, this would probably be all attached and hooked up to it.

And as the engine is put in, then there's, this a snap this and snap that kind of thing. So I really think a lot of it is all manufacturing. Now what you're going to do in this vehicle is 20 years old, you know, to get this hose Ford decides to discontinue it, there's going to need to be some customization for sure.

But the areas that are going to be challenging of course, are these ones with the heater core because they're special fittings. Whereas this could be, you know, you can buy these kinds of T's, that's an easy thing and a straight piece of hose. You can always bend stuff. There's there's lots available you could probably do. But again, I was thinking to myself, 20 years down the road, trucks will probably all electric and most people, unless they want a vintage vehicle, probably won't be repairing this thing anymore. 

Mark: Absolutely. So you mentioned this is an eco boost engine. What's that? 

Bernie: Ford started these a little over 10 years ago. It's sort of the best world of economy, performance and emission. So this is a 3.5 litre V6 engine, it's got twin turbochargers. So it's got pretty impressive specs, like 365 horsepower, 420 foot pounds of torque on this particular engine.

 And there are more modern models and other models with more performance. That have like far better horsepower ratings even than this. So it's pretty cool, but you know, essentially there's much better gas mileage, cause you're not hauling a heavy V8 around and you've got the benefit of of the extra power with the twin turbochargers. You know, on the downside, what I don't like is, there's more complexity, it's not simple. A V8 engine is much simpler. Whereas this you've got a couple less cylinders, but you've got two turbochargers to potentially go bad. And it's direct fuel injection, which causes some issues as well as the maintenance services. 

Pretty reliable, but, and good for economy. But they're definitely more complexity and more to go wrong. So keeping up your maintenance schedule, oil changes. Some direct injection cleanings on a regular basis will keep the engine running along time. 

Mark: And how are these EcoBoost F150 is for liability? 

Bernie: You know, so far at our shop, we haven't really seen any problems with them. And I don't really know in the overall world I mean, I haven't heard a lot that they're a really problematic engine. So I think Ford has done a pretty good job with them. That being said, you know, we don't see a lot of them at our shop. So most of the trucks we see have V8s or diesels but I think they're good. They seem to have been working on, I mean, this truck is 11 years old now, no nine years old getting ahead of myself. There'll be 11 years old in a couple of years. So yeah they seem to be pretty good so far.

2011 Mercedes Benz ML350 DPF Tank Heater

Mark: Hi, it's Mark from Top Local. I'm here with Bernie Pawlik, Pawlik Automotive in Vancouver, British Columbia, Canada. Vancouver's best auto service experience. 23 time winners of best auto repair in Vancouver as voted by their customers. We're talking cars. How are you doing Bernie? 

Bernie: Doing very well. 

Mark: So 2011 Mercedes-Benz ML350 diesel. What was going on with this vehicle? 

Bernie: So the owner was experiencing a check engine light coming on, and then the vehicle going into a reduced power, kind of a limp mode from time to time. So obviously it was a concern, brought it in for us to look at. 

Mark: So what testing and diagnosis did you have to do?

Bernie: Well, first step of course, is to verify the client's concern. We drove it and of course it drove perfectly well . Never went into limp mode, no problems. We scanned the vehicle, hooked up our diagnostic computer. We interrogated the vehicle for codes found a number of codes and different modules, but only one in the engine for a diesel exhaust fluid heater. And so we cleared that. Did a couple more tests, but didn't really find anything conclusive. 

Took the vehicle next day, of course, same day he was driving it, the light came on, came back and we did further testing on it and found that the actual main heating unit in the tank was bad. There's a number of tests you can run on a scan tool looking at current draws and of the various heating circuits. And we found that that one was quite far out of range. So that basically the main heater in the tank was bad. 

Mark: What's a DPF tank heater?

Bernie: So DPF is diesel particulate fluid. Sometimes it's called a reductant tank. But basically what it does is it it holds the diesel exhaust fluid, which is injected into the SCR, the selective catalyst reduction.

Long and short of it, it reduces NOx emission and makes for a clean diesel if there's such a thing. So it's about as clean as you can get. And so this is all part of it. There's a tank that holds the fluid. The fluid will actually freeze very easily. So it has to have a heater in, it has to be kept warm for the fluid to flow. 

So just getting some pictures here.

So there's our 2011 ML350 SUV. So this is the tank removed from the vehicle and underneath here where I'm kind of moving the mouse pointer, underneath here is where the actual heating assembly. We'll have a look at that in a minute, but this, unit on top here is the pump. You can see there's a lot to this. The fluid gets filled here and that's filled through the trunk. It needs to be done every, you know, maybe eight to 10,000 kilometres, depending on the maintenance interval, how you drive it and so on.

There's a hose that attaches here. Of course, it goes out to the injector. You know, there are various wiring components here to pump the fluid, to operate the tank heater and so on. As you can see, there's a lot to it electrically. 

 This is the old heating assembly. So this fits you know, underneath that big round ring, the pump bolts onto the top of it. This liquid here is the diesel exhaust fluid. The stuff is really interesting if you spill it or it spills on the floor, it, it eventually dries into this interesting looking crystal.

 This is where the unit sits. So you can see, these are the two mufflers right at the back of the vehicle. This area here is where the filler assembly is. As I said, you fill it through the trunk and the tank fits in neatly here. The wiring connects up here. So that's basically it that's that's kind of the bulk of it. There was a couple of other pictures I want to show you just while we're out of here.

You know, often, you know, we find other issues on cars, which aren't related, but it's a Mercedes diesel. Oil leaks are a common issue. This is some of the oil that had accumulate on the floor after a couple of hours of service. And a splash pan with a lot of oil coming out of it. So we've talked about oil leaks on these vehicles. That's a common thing. But I just thought, this just kind of caught my eye, and I thought, you know, is there anything else this vehicle needs. Yeah, Well, it's going to need some oil leak repairs. 

Mark: So replacing the tank heater, was that a complex repair? 

Bernie: It's not really that complex. The tank, fortunately it's designed nicely. The tank drops right out, sits in between the mufflers. There's plenty of room and the tank comes out pretty easily. It comes apart quite easily. It's just a few things to transfer over. Part and reassembly, the pump needs to be primed because it can't suck air. So it has to be primed so it's full of liquid and fluid. And adds a bit of complexity, but overall it's not really too much of a labor intensive job. 

Mark: What about the kind of repair costs? 

Bernie: Well, overall, the cost is actually pretty expensive because of course, you know, you've got some diagnostic costs to determine what's wrong with it. Then the labor to replace it, which isn't too much compared to some operations on vehicles, but the the actual heating unit itself, depending on where it's bought is in the $1,500 range, little more from the Mercedes dealer. So it's an expensive part. That's a 2021 chart as a February, 2021 costs. Because if you're looking at this video five years from now and wondering about the cost, it could be less, could be more, you never know, prices have a way of going up sometimes and down at other times, but usually it's up. So it isn't expensive repair overall.

Mark: Okay. For the folks out there who don't want to save the planet, can't you just remove the system and be done with it?

Bernie: Well, you could. But the thing is, I mean, the reason why the customer brought it in the first place is because this vehicle went into a limp mode because the heater didn't work. So it's basically set. So if there's a malfunction in the system, the vehicle isn't going to operate properly.

So what's required to take that out of the equation is to reprogram the vehicle computer. So it doesn't do that. So I know it's probably available somewhere. I have no idea who does it or how you do it. I wouldn't even look into it. I wouldn't do it myself. Cause I really do believe that these things make a big difference to the air that we all breathe.

You know, diesel exhaust is carcinogenic, if care about that at all. It's kind of important not to remove the items. So it's possible and highly not recommended and also illegal. 

Mark: Yeah. If the police find out that you don't have it, they're going to make you put it back. 

Bernie: Yup. And we have a Dodge truck where someone had removed all our emission equipment, a lot more than this, but they had a lot of it removed. It was very, very, very expensive to fix. So yeah, you're really in my opinion, better not to ever remove it, but people do. And it's more complicated on something like a Mercedes, I mean, a lot of American vehicles, it's way more common and way easier to do. But especially in Canada, because you can actually buy the computers you know, to do it in Canada, but in the US there, you can still get them. They're just less legal. 

Mark: How are these ML350s for reliability? 

Bernie: Well you know, they're not the best. We've got a lot of videos on these. There are a lot of things like oil leaks, which I showed you some oil on the floor and leaking through the splash pan. Those are probably one of the bigger issues on these vehicles.

The engine oil cooler seals are a big leak issue. The oil filter housings are another one you know, fuel injectors fail. You know, they develop fuel leaks or different spots? Turbochargers fail. Intake, runners that fail. There are a lot of things that go wrong. And now of course we have the diesel exhaust fluid heater, you know, to add to that. So there's, there's more complexity. 

A great running vehicle, but there are things that go wrong with them and you know, we need to be prepared to spend more money than you would on your average vehicle.
