Mark: Hi, it's Mark from Top Local. We're here with Bernie Pawlik, Pawlik Automotive in Vancouver, Vancouver's best auto service experience, 20 time winners of Best Auto Repair in Vancouver, as voted by their customers in 38 years of maintaining and repairing cars in Vancouver. Of course, we're with Mr. Bernie Pawlik and we're talking cars. How you doing, Bernie?
Bernie: Doing very well.
Mark: So, today's victim, 2009 VW Tiguan that had an oil problem. What was going on with this vehicle?
Bernie: So this vehicle actually came to our shop with a ... It was running very roughly. The check engine light was blinking, which is a serious issue that, I've said before many times, a check engine light if it's just on solid, you need to get some repairs done some time in the future, but when it's blinking, it's serious. It'll create a catalyst damaging misfire, which basically, without getting too wordy, means it'll cost you a lot more money if you don't fix it really, really quickly. So the owner smartly brought the vehicle in and we did some testing and diagnosis on it.
Mark: And what did your testing and diagnosis find?
Bernie: Well, we found a few things. One, there was some problems with the ignition coils. They were worn out. There was misfires in three of the four cylinders. We did a visual inspection. The spark plugs looked pretty old. There was also a little bit of oil seeping down the spark plug tubes, which can cause a misfire problem. It wasn't serious enough to fill the well up with oil, which creates a definite misfire. It wasn't that deep, but there was some oil seeping in. And also, there was a code for a lean air-fuel ratio condition. We did some further tests on that, and we found the engine oil separator was worn out and causing a major vacuum leak in the engine.
Mark: Okay. Oil separator. What causes an oil separator to fail?
Bernie: Well, on these type of vehicles, and a lot of similar vehicles, the oil separator, it's like a PCV valve. It's a crankcase ventilation valve. Some cars, they call it an oil separator. They do on this particular vehicle.
What this oil separator unit does is, it allows crankcase gases to be sucked into the intake manifold to be re-burned. It's a pollution reduction device, very effective. But if it doesn't suck the right way, it'll suck engine oil right out of the engine, into the intake manifold. Of course, then you have blue smoke and a whole bunch of other problems. So the oil separator separate ... prevents the oil from actually getting into that, getting mixed in with the crankcase gases. So that's how the unit works.
Mark: So positive meaning basically that it's taking what would be negative pressure and turning it, using that to pull the gases out of the crankcase and to be re-burned?
Bernie: Exactly. In the past, and we're going way back in the past, unless you look at a Dodge diesel from the mid-2000's, which they actually still add a road draft to, believe it or not, crankcase gases were vented out to the atmosphere. This was actually one of the worst pollutants that an internal combustion engine can make. If you smell it, it's the most noxious smelling fumes, because it's not really burnt gases. It's just gases that have escaped past the pistons, mixed with a bit of crankcase oil. It's a horrific smell, and really, really bad for the environment. So, it's one of those pollution devices that actually really is very effective and really doesn't rob an engine of any power at all, by doing it. It probably does a tiny bit, but it's so minute, you'd never notice it.
Mark: So what's the difference between a positive crankcase ventilation valve and an oil separator.
Bernie: I would say complexity is kind of it. But you'll find this term used on a variety of different vehicles interchangeably, European cars. I'm just actually going to show some pictures right now.
This is our Tiguan engine oil separator, or PCV valve. The PCV part is kind of in here, but this is the top side view. This is what you'd see if you look on top of the valve cover. This is the underside view, so this is with the unit removed. This is what sort of sits against the valve cover, so there's a gasket here. There's a number of passageways and rubber valves inside. You can't really see anything. That's why you basically replace the whole unit, because there's nothing serviceable on it. But the good news is, you can actually service this unit. It's a separate replacement unit.
Now, compared to a PCV valve, this is a PCV valve that's ... this is very commonly used, starting in the 1960's up. You'd find this on American cars, Japanese cars, earlier European vehicles. Nowadays, some cars still use this PCV valve. It does exactly the same function, believe it or not. This part costs about, I don't know, you can probably buy it as cheap as two or three bucks for some vehicles. But for some reason, European vehicles, they decided to get really complicated. And they fail a lot more frequently.
These PCV valves used to plug up, in the olden days. Again, they were cheap to fix and you could, every time you changed the oil, or every second oil change, you could pull it out, shake it, rattle it, if it moved, then it's good and you could keep it. But anyways, that's not the case in the Volkswagen. It's much more complicated. So there's our little picture show for the day.
Mark: Any idea why it's mostly European or VW vehicles?
Bernie: Yeah, well it's interesting you say that, because it seems to be mostly European vehicles that have this type of system. It's not just VW, it's even Range Rover, which is an English vehicle. I don't know, maybe there's an engineering school in Europe that all the automotive engineers go to, and they all learn to make a crankcase vent valve. Because it's interesting, when you look at cars, how on different continents, they have their unique ways of doing things, even though they're all the same, the internal combustion engine is the same thing.
But you won't find these kind of PCV valves, generally, on American cars, although they're starting to get more complex. But yeah, you'll find these on Porsches and Volkswagen, BMWs are famous for failing, Mercedes almost never. So they've got those built pretty different for Mercedes, but certainly the Porsche, VW, Audis, BMWs, they're all common failure. Land Rovers as well.
Mark:So what's involved in replacing this oil separator on the Tiguan?
Bernie: Well, on a Tiguan, fortunately it's not too difficult. It bolts on top of the valve cover, reasonably easy to remove and replace. So that's positive, because a lot of them are not such. A lot of BMWs, and it's a high failure item on a lot of BMWs, involves removing the intake manifold to access the crankcase vent unit. And there's a bunch of other plastic pipes that tend to break and crack at the same time. There are certain VW and Porsche products where you actually have to replace the whole valve cover, because that actual ... All the components are inside the valve cover. I mean, really brilliant idea. I mean, great from a manufacturing point of view. I'm being a little cynical. But when it comes to repair and replace, it becomes much more complicated. So on the Tiguan, it's pretty good. It's a decent job, not too crazily expensive.
Mark: So you mentioned oil leaking into the spark plugs. What did you do about .... spark plug tubes. What did you do about that?
Bernie: Well, at this point in time, we determined the leak wasn't severe enough to actually repair the leak. Normally, we would say, "Hey, let's just do a valve cover gasket and put new spark plug tube seals." But, that's not possible on this one, here. The good news is, the crankcase vent valve is easy to replace. The bad news is, doing a valve cover gasket on this particular engine is extremely complicated. You actually have to remove the entire cylinder head, and then disassemble it and the valve cover's all part of that. So we determined with the amount of cost and the amount of leakage that it would be best for the owner just to leave it and monitor it for the time being. It would have been a very expensive job. So, from an engineering perspective, that wasn't such a win for Volkswagen. But I'll give my thumbs up for the crankcase vent valve, or the engine oil separator, I should say.
Mark: How are Tiguans for overall reliability?
Bernie: They're not too bad. The key with any of these modern vehicles is maintenance. Change your oil regularly, and change it more frequently than the manufacturer recommends. A lot of them have very long oil change intervals with synthetic oil. Just do it, run it 75% of the time or less than they recommend. Then you're in the safe margin. You're in the safe zone. Combustion chamber cleaning, really important on these things, because they're a direct fuel injection, the valves can gum up. Or not gum up, sorry, get pretty serious deposits. So it's best to deal with those sooner than later. I'm losing my voice here. Sorry.

Mark: Hi, it's Mark Bossert, producer of the Pawlik Automotive Podcast. We're here with Bernie Pawlik of Pawlik Automotive in Vancouver, 38 years servicing in maintaining cars in Vancouver and 20 time winners of Best Auto Repair in Vancouver, as voted by their customers. And of course, we're here with Bernie Pawlik talking cars. How you doing, Bernie?
Bernie: Doing very well this morning.
Mark: So, this week's victim is a 2012 VW Tiguan. I always choke a little bit on VW. Water pump replacement. What's going on with this vehicle?
Bernie: Yeah. It's okay, Mark. It's a gas motor one. They haven't faked us out on these ones. Yeah. So this vehicle came to our shop. It had a coolant leak coming from under the hood, obviously, so we proceeded to do some diagnosis and testing to figure out what was going on.
Mark: What'd your testing and diagnosis find?
Bernie: Well, what we found was a coolant leak coming from the front of the engine kind of buried under the intake manifold. We'll look at some pictures in a little bit and you can see how typically complex this thing is under the hood. But there was a leak coming from around the area of the water pump, and that's where we proceeded next.
Mark: So, what was your next step?
Bernie: Yeah. So next step was we verified the area of the leak. Couldn't see it exactly, but it was around the area of the water pump, so we got in and removed the water pump, and that's where we found the issue.
Mark: What did you find?
Bernie: What we did we find? Here's a picture. This is the surface where the water pump bolts up to the engine block. The red arrow points to the area of failure here. If you look here, you can see there's a plastic channel. There's the channel there. Part of this plastic here is just basically broken away, allowing this O-ring to just flop out of place. Of course, it causes coolant under pressure to just blow out this way right down the side of the engine.
So, I know I say jokingly, we love plastic. I don't like to own plastic car parts because they wear out, but they do create a lot of work for us because they do I think tend to fail earlier than they should in many cases. This is sort of the backside of the water pump housing. This is the drive gear over here, but this is basically the area of failure. So the whole water pump assembly needs to be replaced. So that's what we found.
This is a view of the engine with the covers and everything on. The water pump is located down in this area here below the intake manifold. Again, there's a lot of work to access it and get at it. This is a view underneath the vehicle of the new water pump installed. You can see the drive gear, the hose outlets. There's a lot of complexity to put this pump in. There's a number of different connecting pieces. You can see a piece of the thermostat in there and the actual water pump impeller is in this area here. So the actual water pump itself is made of aluminum, but the housing is all plastic.
I think we have a final photograph to look at here. Again, this is a view down the engine with the plastic cover off the top. You can see the ignition coils and a little more of the area of the intake, but again, the water pump's buried under here.
I'm actually gonna go back to this picture of the water pump because this thing has a unique drive system. You see this cogged pulley here. It's actually driven by a tiny little drive belt. Looks like a little mini timing belt. I should've taken a picture of it, but it's about, I don't know, maybe four inches long and it goes to a drive pulley located under this area here. It actually involves removing that pulley to put the belt on. So that's another item that gets replaced at the same time as the water pump, because of course if that belt breaks, the pump won't turn and things will need to be done. The belt was starting to crack at the age of the vehicle so it was a good time to do it. But yeah, really complicated little job.
Mark: So why would they use such a complicated system? Just to fit it in the vehicle?
Bernie: Yeah, just to fit it in the vehicle. The plastic, again ... I'm just gonna go back to sharing that picture of all the plastic here. You can see there's a lot of plastic in this area. There's plastic down here. The top of the engine, the valve cover's all plastic. The intake manifold's plastic. You got covers here, ducting. I'm kind of drifting off here 'cause why they fit it in, but there's a lot put into the engine compartment, so they tend to put things wherever they can. I mean, that's kind of a quirky drive system, but I guess the engineers go, "Well, that's a good spot to put it. Let's put it over there." Kind of like our Volvo we talked about a few weeks back where again, they put the alternator underneath the intake manifold and drive the water pump with kind of a crazy pulley system on the backside of the engine. But wherever they can fit stuff in the engine compartment, gets the car out the door, they can sell it and you as a consumer have to deal with it later.
Mark: Yeah. This is kind of a smaller size SVU.
Bernie: It is, yeah. It's a nice compact sized SVU. I mean, it's a really nice vehicle. Drives great. Good performance, decent fuel economy. I can't really see anything wrong with it other than that but along with the compactness comes complication. I don't know if there's any escaping it. Some brands are just more reliable than others.
Mark: And how are Tiguans for reliability?
Bernie: I'm gonna put them in the fair category. I mean, you get things like this plastic failure is common. Over the years, we've done a lot of ... You can probably look at a video we've done a few years ago or a blog post. I talk about plastic in VWs. It's an item that does fail a lot and causes the consumer extra money to fix, but overall it's a pretty decent car. I think my comparison was always you'll spend a little more money fixing this than a Toyota and there will be a few more things that will go wrong, but other than that, it's a pretty decent vehicle.

Bernie: Thank you Mark, and thank you for watching and listening.
Mark: Hi, it's Mark Bossert, producer of the Pawlik Automotive videos and podcast. We're here with Mr. Bernie Pawlik, Pawlik Automotive in Vancouver, servicing and maintaining vehicles in Vancouver for quite a few decades. And also 19 time winners, only 19 time winners of Best Auto Repair in Vancouver, as voted by their customers. How you're doing, Bernie?
Bernie: Doing very well.
Mark: So, we're talking about dash warning lights. We're going through a little series on this, just revealing maybe some of the things that you could find out for yourself if you looked in your owner's manual, which most of us don't do. This is for a 2012 VW Jetta TDI, which is a diesel version. What's going on with the warning lights on this VW? What do they mean?
Bernie: Yeah, well. Before we look at pictures, let's just talk about their ... I mean, there's essentially two basic colours of warning lights. There's amber, and there's red. And so red are the like stop light kinda thing. You gotta ... it's serious, you gotta deal with this right now in some way, shape, or form. And amber is something that's ... it's a caution. There's something you need to attend to at some point, but not immediate. Those are basically most of them. I mean, other than, there are dash lamps sometimes that are green or blue, like the blue one will usually mean for the high beam light. But these are not so much warning, they're just information lights. Yeah, so that's basically the key. Again, red is like stop. Amber is like caution.
Mark: And amber is just a fancy name for yellow.
Bernie: Yeah, exactly, yeah, yeah, but it's actually am- ... I was going to say amber or yellow, but it's like, you know.
Mark: So let's get up a picture of the dash and see what's going on.
Bernie: Sounds good. Okay, so you can see the dash here?
Bernie: Okay. Alright, so this is basically a view of the dash, when you turn the key on and for a couple seconds all the lights will come on. And that basically, they're on to tell you that the actual light bulb is working, and the indicator itself, the system's actually working. So, we'll just start over in the right hand side here. We've got a few ... so this is, again, an amber light. This for the airbag system, that there's a malfunction in the airbag. Some vehicles, this will actually be a red light, but on the VW it's an amber light.
ABS brake system at fault. This is for the traction control system. So those are our amber lights, again these are like sort of indicators that something isn't quite right, but not necessarily wrong. And sometimes these things will blink. The traction lamps sometimes will come on. The traction control system basically keeps your, essentially your wheels from spinning when you're accelerating hard. That will be one of the things. And so you happen to sometimes, say, on a snowy road, you accelerate hard, this light might blink, indicating that the traction system wasn't able to give you traction. But it doesn't indicate really a problem, that's just normal.
This is the ... I'm just looking around here. Yeah, so this is brake warning light, and this can often be multi-function. This can also be ... this can indicate the parking brake is on. It can also indicate that your brake fluid level is low. So, that's if your parking brake is not on and the light's still on, have your brake fluid level checked or check it yourself.
This red light hiding behind here, this is a seatbelt warning light, that your seatbelt is not on. So again it's red, it's like urgent, they want you to have your seatbelt on. And this green light that's hidden back here, it actually has a ... I think it has a view of a foot. This is to indicate to push the brake pedal down to shift out of park, so that light I believe usually goes off when you push the brake pedal down. And once you shift out of park the light's off.
So we move over to the left side of the dash, now we have ... again, we'll go over the ambers first. The check engine light. Again, if this light comes on, it indicates you need to have something looked at on the vehicle related to the emission system or engine performance. If it's blinking, however, that can indicate a catalyst damaging misfire. Now this is a diesel, so I'm not certain in terms of blinking on diesels when or how that occurs. But on a gas lean engine vehicle, if it's blinking you need to get it fixed very quickly before you cost yourself more money.
Of course, that looks like a gas can, that's your low fuel warning light. On your left, the glow plug light. So, when you turn your key on normally this will illuminate for anywhere from a second to maybe a few seconds if you're in a cold climate. And as soon as that light goes out, then you start the engine, so that indicates the glow plugs are on. That's to warm up the engine to start.
And this indicates that the catalyst, or the exhaust particulate filter on this vehicle is got too much soot in it. And again there's caution and service that needs to be done around that. We won't go into that here.
On the red light side of things, that's your temperature warning light, so that could be your engine's overheating. This is a critical thing. If that light comes on, shut the engine off and figure out what's going on with it, or take it in. Same with this one here, this oil can light. If the engine is running and that light is on, that's a bad thing. So make sure you shut the engine off immediately and have it serviced, diagnosed.
This light here, the battery, looks like a battery. It indicates that the charging system voltage is low, it's not that the battery's bad. So what will likely happen, if that light comes on while you're driving, you'll probably have a dead battery soon. So again, that's something that needs to be tended to pretty quickly.
And this light here that looks like a steering wheel indicates a fault with the steering system. These vehicles use electric power steering, so this would indicate a fault with the electric power steering.
Now, that's basically all the lights on the dash that are on right now, but I did actually take a couple of photographs of the manual.
If you own this vehicle, I mean go through the manual and have a look at it, because it explains what all these lights are, and actually ... so there's a few things I missed, I'm not going to go into all the details here. If you have the car, get a manual. You can usually find these kinda things online, but it has a list of the red lights. And then if you have a look over here it has a list of the amber lights I think come on for different issues. There's also a few green ones as well, but these are usually just related to other driving issues and not anything of any concern with the engine or operating system of the vehicle. And that hereby ends our picture show.
Mark: So how different will the warning lights be on a gas engined VW compared to this TDI?
Bernie: That's a good question. Not a lot different. The only major difference, of course, you won't have a glow plug warning light on the gasoline engine because they don't have glow plugs, and also that soot filter light will not be there. I'd say that there may be on a gas ... yeah, that's pretty much, those lights won't be there. I'm not sure on a gas engine if there'll any extra ones. Probably not. So there'll just be an absence of two lights there. But again, look through your manual. The key is look through your manual and just kinda get used to it. But again, if there's any red lights on, the key is to shut the vehicle off right away. Look and see what the information is. Call a mechanic you trust, or a service facility you trust and figure out what's going on with it.
Mark: Great, so this is in your range of VW's cheating software system that allowed them to fake good emissions when they actually had really poor emissions, and recalled lots of vehicles. Thank you, they paid me a lot of money for mine. Do you work on many of these?
Bernie: Oh yeah, we still see lots of them. I mean, there's still lots on the road. I mean, they've either fixed them up or people ... I'm not even sure what everyone's chosen to do. It's kind of a story that's sort of filtered away in the back burner. I mean Volkswagen doesn't sell these diesels anymore. But yeah, we still work on lots of them. I mean, they are a very good vehicle, and obviously from an environmental standpoint I'd say they're a lot better than diesels have been in the past, but they're obviously not ... they weren't what they were supposed to be, and that's why they got into trouble, and ... but yeah, other than that, I mean, it's a great vehicle. It's very good.
Mark: So there you go. If you have a VW dash warning lights, you need some more information, have a look in your ... or whatever vehicle ... have a look in your manual and you'll find out what's going on up there.

Bernie: Thanks, Mark, and thanks for watching.
Mark: Hey, it's Mark Bossert here. Producer of the Pawlik Automotive podcast. We're here with Mr. Bernie Pawlik in Vancouver. How are you doing this morning Bernie?
Bernie: I'm doing well.
Mark: So, 19 time winners of Best Auto Repair in Vancouver and 37 years of repairing vehicles and maintaining vehicles in Vancouver. We're going to talk about a 2002 VW Jetta TDI that wouldn't start. What was going on with this vehicle?
Bernie: Yeah. So, this vehicle was towed to our shop with a no start condition. The engine would crank over fine, but it just wouldn't catch, wouldn't start. So, we did some diagnostics on it, as we usually do, and found a few interesting things.
Mark: What did you find during your diagnosis?
Bernie: Well, the first thing is, is the gas gauge was reading fully empty and that kinda had us concerned. So we talked to the owner and he said, "Well, the gas gauge is kind of intermittent. Sometimes it works, sometimes it doesn't." There was definitely an issue going on with the gas gauge sending unit. We did verify, in fact, that we couldn't pull any fuel out of the fuel tank. So, our first step was to find out is it actually in fact out of fuel. We did verify that it was out of fuel, but there was another interesting thing that we found known addition to that too.
Mark: So, what was the extra problem that you found that was more than just fuel?
Bernie: So, we found, actually, that even after we'd added fuel the fuel tank strainer was blocked. That sits, fortunately for the client who had a malfunctioning gas gauge the strainer and the gas gauge sending unit are all one piece. We pulled ... You can access this through the rear of the vehicle. You don't have to drop the fuel tank as you do in a lot of vehicles. We were able to access the fuel pick up unit with the sending assembly, gauge sender assembly through the back seat of the vehicle, under the back seat and remove it. We found the strainer was plugged full of debris, which is not an uncommon issue on these vehicles. It does happen from ... not a lot, but from time to time. So, we'll just go into some pictures right now. So, there's a nice specimen of a 2002 VW Jetta TDI. And onto pictures ... So, this is the fuel sending unit. This is the old one in the vehicle. And this is a sort of bowl where the fuel sits, and fuel is stored in here and it's picked up and sucked through here. You can see all of this black debris. That has basically blocked off the fuel system from sucking any fuel into the fuel pump, the fuel injection pump. So, the new unit ... We'll get to right here. That is basically the new fuel sending assembly. So, this is the whole unit together. This is the gas gauge sender. So there's a float here, and this floats up and down in your gas tank. You can see its got a little arm, and this'll float, move up and down depending on how much fuel's in the vehicle. This little electrical rio stat here will send a signal to the gas gauge and then you'll know how much fuel you have. So this item wasn't working. Also, the strainer which is inside here, that was the picture you were looking at, sort of the view looking down here. That's been replaced so kind of killed two birds with one stone in this case.
Mark: So, I've had a couple of newer versions like this vehicle. They were a little bit less forgiving, perhaps, because they were high pressure fuel systems. But I definitely had issues with running bio diesel in cold weather. Was there any kind of issue in that regard? Like, why was there so much dirt in there, or debris?
Bernie: I mean ... I think it's just that it accumulated over time. I'm not really certain how that dirt got in. But, I mean normally fuel is filtered when you buy it but it's never 100%. That's why vehicles have fuel filters. Although, interestingly enough most gasoline engines, actually for the last 20 years or more, have actually had ... The fuel filters been largely eliminated as an extra piece. The actual filtration happens right in the gas tank. Rarely with a gas engine do we ever see any problems. Because I think the fuel processing system and delivery is just so clean that it actually works that way. In the past, you know, it wouldn't have been so. But, with diesel I guess, you know obviously there's some debris and things have accumulated over time. These vehicles usually last a long time too. So, you know, it's a 2002 that makes it, what, 16 years old. You know, there's quite a few kilometres and years of pumping fuel through the vehicle. So, the debris just builds up.
Mark: And as you mentioned, this is a 2002 Jetta. How is it for reliability?
Bernie: These are still really good vehicles. The fuel system is ... it's more mechanical in this version than it is on the newer ones. More mechanical, less electronic. It works really well. It's kind of a nice, sort of, era where the blend between the fully mechanical and the more electronic diesel's ... It's kind of half way in between that. It actually works pretty well. I mean, these cars are getting ... you know, they don't have as much value as they used to. So, repairs can get expensive. But over all they're still pretty good cars. The actual base engine itself is really solid. It just, often the fuel system starts to cost money when you get to this age of the vehicle. But, this was a fairly simple repair and not to costly.

Mark: Hi, it’s Mark from Top Local, we’re here with Bernie Pawlik, Pawlik Automotive in Vancouver, Vancouver’s best auto service experience, servicing and repairing, maintaining cars in Vancouver for 38 years and 18 time winners of Best Auto Repair in Vancouver as voted by their customers. How’re you doing Bernie?
Bernie: Doing very well.
Mark: So we’re going to talk about a 2007 VW Toureg 3.6L, this is one of the VR6 engines and you had to do a valve cover replacement. What was going on that you needed to change the valve cover?
Bernie: What was going on, was this vehicle came to our shop, engine wasn’t running quite right. We did a scan and diagnostic on the vehicle and found there was a trouble code for a lean fuel condition and traced that to being a leak in the crankcase ventilation system and the crankcase ventilation valve happens to be built inside the valve cover. So that’s why the valve cover needed to be replaced. It’s not a separate unit. It’s all a modular piece.
Mark: Ok, that sounds a bit strange because a PCV valve is fairly regular maintenance item. So it required, why would they change it to make that simple part be part of the integral to the whole valve cover?
Bernie: Well I’d say why was probably from a manufacturing point of view. A lot of things on vehicles are done on a I call it a modular fashion, in other words, they kind of look at things and ok the crankcase ventilation valve, kind of part of the valve cover sits there, why not just put it all into one unit and when we build the engine we can just stick it all together and it makes it easy. So from I think a manufacturing perspective, it makes it a whole lot easier than having a separate component, like a simple PCV valve. Where you could actually unscrew the thing and replace it which would be like really simple and which used to be and it was the kind of part that a lot of times you go, even if you go to a quick lube shop and they’d go, oh there’s the PCV valve on top of the valve cover. Let’s just put one of those in because it costs $5 bucks and we can make an extra couple of bucks while we’re doing an oil change and it actually services that part. Nowadays it just gets stuck inside. Now granted, these are a little more just, a little more complex to the simple PCV valve and they flow a little more air, but really yeah why not put in on the outside and make it a whole lot easier to fix.
Mark: So you have some pictures?
Bernie: Yeah I do. Let’s have a look at some. Nice little 07 Toureg and we can go into the engine. So there’s the engine. Again, as you’re saying Mark, it’s a VR6 design engine which has been around for a while. Unique Volkswagen concept which works quite well, very compact for space and you only have one cylinder head which is kind of neat which instead of having a V which has two. Anyways, the valve cover is located here underneath the intake manifold and there’s a lot to get off to do this job. Manifold is not just a simple replacement. It has a direct fuel injection system and two fuel rails hidden, one under here, one further down, if you can see my mouse pointer, these both need to be removed in the process. And then the intake has to come off and then of course, all the ignition coils, the spark plugs, sorry just the ignition coils and then you have the valve cover located right in the middle. So it’s a few hours worth of work. It’s a lot to be done. Then we look at the valve cover. There’s the valve cover. This is the old one, it’s off and of course they don’t sell parts. The piece is located inside here. This is the breather hose, it goes off to the intake, and this is the inside view of the valve cover. So this is, that breather pipe is over here, there’s a valve in here and an air intake section here. So what will happen is the valve, it’s a rubber diaphragm valve sitting in a very hostile environment with noxious crankcase fumes and oil vapours and just really, just stuff that’s really hard on rubber and eventually the rubber diaphragm deteriorates. It rips a hole and it’ll end up sucking a lot of air through the engine. So that’s what causes the lean fuel condition. The engine’s actually, the system sucking air that it’s not supposed to and also cause a lot of pressure and suction in the crankcase as well. so anyways, that’s what we, that’s a little view of everything in there.
Mark: Ok, so let’s do a little comparison. The old PCV valves, maybe even from the 70’s, how often would those be, how often would you change those?
Bernie: Well, probably, they used to get changed probably once a year when you do a tune up on an old car like that. But how often do you really need to change them? Probably every 2 to 3 years. They would basically, the most thing would go wrong with those type of PCV valves, is that they’d end up getting plugged up with sludge and carbon deposits, you know as the crankcase gases are flowing through it eventually it leaves vapour on it and they’d end up plugging up. So that’s what would cause that.
Mark: And what about these new style ones, where that PCV valve is incorporated right into the valve cover?
Bernie: Well this vehicle’s 10 years old and it’s failed, so that’s kind of a , I would say, probably the average life span of these, but VW isn’t the only manufacturer of these. I mean there’s a lot, we did a Chevy Cruze a while ago that had a similar issue. Not that old of a vehicle, probably 100,000 kilometres, I don’t know 3 to 5 years old vehicle and the same kind of issue. And again, on that one, you have to change the whole valve cover. So that’s kind of the way a lot of auto manufactures are going. It’s all modular and some of them don’t last as long. Fortunately the Cruze was a substantially cheaper job than it is to do a valve cover on a Toureg.
Mark: And as we’re enjoying the lovely sounds of the emergency services speeding past…
Bernie: Yes, yeah the advantage of having your business on a main road.
Mark: How are these 3.6 litre VR6 engines for reliability and servicing?
Bernie: Well as far as reliability, they’re pretty good. You know, we don’t do a lot of, you don’t find a lot of things go wrong with them, I mean this is sort of one of there major things but they are potentially and extremely, I should say as far as servicing, I mean the oil changes are a bit of a pain to because the oil filter is located under the engine in a tricky to access spot. This particular engine actually is used on the Porsche Cayenne and An Audi Q7, so you’ll find a few different platforms of vehicles. But they’re all a little bit of a pain to access the oil filter. So the oil changes are a bit more work than they could be and there’s a lot to go wrong. I mean, there’s a lot potentially expensive repairs. The timing chain is on the back side of the engine so if it ever fails, it used to a lot in older VR6’s, not on these, but the old VR6’s, the timing chain failure was common. You have to pull the engine out to get at it or take the transmission out to access the timing chain. So it’s a lot of work. I don’t know why they built these things backwards but I guess the expectation is you’re never going to need the service it which is my thinking or if you do well too bad you’re going to have to pay for it. But other than that you know, they are actually quite a reliable engine.
Mark: So basically the VR6, just to digress for a second, is a V6 squished together in to still alit bit out of a line, but the cylinders are sort of, I don’t know how you describe it without showing a picture of it, they’re just sort of squished together but offset from each other?
Bernie: Yeah a typical V engine might be you know, I’ll just use my hands for example like a lot of V engines would have the cylinder banks would be like you that sort of 45 degrees and there’s a variety, some are wider, some that are narrower. But a VR6, what they’ve done is they’ve actually, I think it ’s a 15 degree bank. It’s very close. They kind of offset the cylinders so that one sits sort of unaligned. So they just kind of used the open space, it’s actually brilliant engineering and so they’ve incorporated the V engine into one cylinder head, with one cylinder head, one engine. Well you know they all have one engine block but just one cylinder head to do the whole job. So it’s a pretty neat feat of engineering and really it generally, they’re pretty reliable over all. As I said, the older VR6 the timing chain failure was a common thing but they seem to have eliminated that as an issue. So yeah it’s good, it’s compact which is a neat thing about it. It doesn’t take up a lot of space which is kind of a brilliant part of it.
Mark: So you get the power within a smaller space basically?
Bernie: Exactly, exactly and that’s important in modern cars. When you look, you know, they build a car smaller, there’s less hood length, there’s a lot more accessories and things stuffed inside. So it makes sense in a modern car whereas in olden days, you’d have hoods that are like you know, a 4 by 8 sweet of plywood would fit under there, you could fit that under there. I had a friend that had a Plymouth Fury, a 1968 Fury had a straight 6, one of those famous Dodge slant 6 engines, you pop the hood and there was enough room to stick a second engine beside it. So much space, you know it was crazy. But not like that anymore.

Bernie: Thanks Mark.
Mark: Hi, it’s Mark from Top Local, we’re here with Bernie Pawlik, Pawlik Automotive in Vancouver, 38 years of repairing cars in Vancouver and 18 time winners of Best Auto Repair in Vancouver as voted by their customers. How’re you doing Bernie?
Mark: Fantastic, because I know you were a little bit sick earlier this week, so we’re talking about an old VW, a 21 year old VW Golf that you had some work on, what was going on with this vehicle?
Bernie: This vehicle had a really bad clunking noise coming from the rear and the rear struts were worn out so, and in all fairness has been a client of ours for quite a long time and we knew the struts were wearing but I want to talk about this today because I mean just the amount of wear on these struts before the replacement was horrific. It’s just very interesting to kind of look at and just talk about the struts and old VW’s.
Mark: So there’s lots of noise, what else was going on when the vehicle was being driven?
Bernie: Well mostly there was just noise, I mean when you drive the vehicle and I mean any of the little minutest amount of a bump, I mean even a microscopic bump there’d be a creak and a bang in the back of the car. As I mentioned it had been going on for quite some time but this person has been a regular client for quite a while and being an older car, it needed a lot of work. So we fixed up what needed to be done, the priority items and the struts were not on the priority list initially by they certainly became high on the priority list. Especially when the vehicle was in for the last service about a month ago, it had a bad wheel bearing problem which is pretty severe in the rear. So we serviced that, fixed all that up and we noted that the rear struts of course had deteriorated so badly in fact you could take the back wheel and rock it back and forth like quite a lot. And you could see the strut, there was play in the strut, just a massive amount of movement. So I said, hey you know, you’ve got to fix this as soon as possible, so recently as soon as possible happened and we fixed it. I’m going to share a couple of pictures because when we took it a part, it’s just interesting to see just how badly worn a part like this can be. I’m going to actually start with a picture of the repaired strut. So this is what a good strut looks like, this is the actual strut part that got replaced. You can see this rusty piece that’s the coil spring. In this case, we did not replace it but this accordion bellow piece here was replaced and there’s a piece up here called the snubber which is a little like a foam cushion when you, if you hit a bump to hard it’ll actually prevent the top of the strut from hitting the strut plate and then what’s not in the picture is the strut place which is just out of the picture, and that’s what mounts the strut to the vehicle. This forms a sort of top part of suspension, it keeps the wheel from you know flopping in and out. Plus it also provides the shock absorbing spring motion. So that’s why I like a MacPherson strut. It’s a pretty unique component. It actually eliminates a lot of parts that you find in other suspensions. Now here’s the broken part. So I put a couple of nice arrows here, now this is actually at the bottom, we removed the bottom mounting and basically the strut just fell apart. You can see the spring has slipped down and normally this wouldn’t happen. The strut would actually stay in place but because it’s so badly work at the bottom of the strut tube has actually broken off inside. So this is the outside tube and this is the piece that moves up and down when you hit bumps. The red arrow basically sort of points to the separation of the two components and then the yellow, I’m just pointing at the tube and you can see this ugly brownish colour, there’s oil inside struts and as they wear, they leak and of course water gets inside. That’s just an emulsified oil with a boiled water mixture, it’s just kind of ugly. So a good indication if your struts are actually wearing is if you know, you see actually fluid, like an oil seeping out of the strut. That’s a good sign the struts are on their way out and need to be replaced. So there’s a couple photos of what we saw. I don’t have a video of the actual, of the initial movement of what was there but trust me, it was pretty scary.
Mark: And is this a difficult replacement?
Bernie: Not really too difficult on this vehicle. It does involve some removal of the interior to access the upper strut bolts but the job itself is not too difficult. This strut came, it’s not available in bits and pieces. We had to actually order whatever parts we needed which is why the spring is still old. But what we do in a lot of newer cars and it’s available for many models, a part they call a Quick Strut or I think other manufacturers have different names for it but that’s Munro’s name a Quick Strut. What it is is a complete assembly. It’s the strut, it’s the upper mounting plate, it’s the coil spring, everything is brand new. So you just unbolt the assembly, bolt in a new one and you get all the new parts, so it actually makes for a really good job. Probably a little more expensive than replacing bits and pieces but then you’re not going to forget something and find later, of it’s making a little clunk or thump, the springs are a little soft. You get the complete job. It’s like restoring the suspension back to new. So it’s a really good option and we use it wherever we can. But in this older VW, you can only buy the strut and the mounting plate, bits and pieces.
Mark: And how did it ride?
Bernie: Oh much better, yeah no noise, smooth and of course safe. You know I mean what would happen is eventually if it broke apart, you know the spring would fly out, I’ve never seen it happen because nobody I’ve ever seen anyone leave that far but you know it could take maybe a little bit longer for that to happen like you know that the spring could fling out, that the wheel could flop out to the side or something like that. It could be pretty scary. But anyways, much safer, nice quiet ride.
Mark: 21 year old Golf, is that, would that still be a worthwhile used car purchase?
Bernie: Well it could be if I mean, first thing I would never buy one with an automatic. Like ’96 to about ’06 VW somewhere in that year range, with automatics were really problematic but if it’s with a standard transmission, well maintained, you know it’s obviously not going to be a very expensive car, but you now if you’re looking for something inexpensive it could be a decent used car. Again with a mechanics inspection.

Bernie: Thanks Mark
Mark: Good morning, this is Mark at Top Local. We're here with Bernie Pawlik, Pawlik Automotive in Vancouver, the world famous Bernie Pawlik. They are 18 time winners of Best Auto Repair in Vancouver. Eighteen times, as voted by their customers. How are you doing, Bernie?
Bernie: Doing very well.
Mark: We're going to talk about a ... We have a weird glitch. I'm going to freeze the camera to you. We're going to talk about a 2006 VW Jetta, a TDI. This is a unique kind of version of this vehicle that was only available in 2006, I think. Is that right?
Bernie: No, there was a few, a couple other years that I, off the top of my head I can't remember the exact, but not much as 2006. There was only two or three years in and around that.
Mark: So what was happening with this VW diesel?
Bernie: A vehicle came to our shop and it was running rough, had a lot of noises coming from the engine. It was pretty apparent within a short drive there was something pretty serious going on. You know, it had a slight misfire but there was ... You know, diesels are always noisy, but there was just this excessive noise that you could tell wasn't right with the diesel. We did some diagnostics on it, and what we found was that the cam shaft was worn very badly, cam shaft and lifters.
Mark: So what kind of diagnosis did you have to do to get the that point?
Bernie: The initial diagnostic with the scan tool, extracting codes, and off the top of my head, I can't remember all the exact codes we had. I know there was one for glow plug, which is relevant. Not relevant to the issue, but there was at least one or two misfire codes, which indicate there's a problem with the cylinders. After that, with that level of noise, it's really a matter of listening, where is the noise most present and then taking things apart. So we pulled the valve cover off and that where we discovered the cam shaft and lifters were extremely badly worn.
Mark: Okay, so what ... I've had one of these 2006 TDI Jettas that was pretty reliable. What could cause this kind of severe wear on the cam and lifters?
Bernie: There's a lot of, I wouldn't say controversy, but opinion on it is people using the wrong oil is one of them. This engine's kind of unique. It uses ... The fuel injection system in this engine uses an actual injector that's driven from the cam shaft and the high pressure fuel is actually delivered into each injector from the cam shaft. There's an extreme amount of pressure on the cam shafts that isn't present in a lot of other engines. Using the right oil, I think VW spec 505.01 is the prescribed oil. It's usually a 540, I think there's a 530 as well, but anyways, you need to make sure you use that spec of oil. Even with that, if you go too long between oil changes, that always causes excessive wear, and some people have even said that it's just the design of the engine is just vulnerable and weak, anyway. This vehicle did have over 200,000 kilometres on it, so that's a pretty fair amount of time, in all fairness, but it is a pretty common problem having these cam shafts wear. Critical to use the right oil, of course, and change your oil at the right interval.
Mark: So, I know my own TDI had over 200,000 kilometres before I traded to a 2010. Do you see this issue often with these engines?
Bernie: You know, we actually haven't seen it that often in our shop. It actually seems like a lot of the TDIs we work on seem to be a generation earlier than this, or a lot newer than this. We haven't seen a lot of this, but I'm certain that we're going to see a lot more of it, because there are a lot of these engines around, a lot of these cars, and they still have good value and worth keeping. It's out there, it happens a lot, and sometimes there's a first for everything, so this is one of our first ones with a worn out cam. But it's out there, and something to be cautious about if you're buying a used Volkswagen, make sure it's running properly and it's in good shape and well maintained.
Mark: So, an expensive repair?
Bernie: It is, yeah. It's an expensive repair. It's a lot of labor. This one needed timing belt to be replaced at the same time, too. It looked like the timing belt was very old and probably hadn't been done. My guess, the owner of this vehicle had bought the vehicle recently and it probably hadn't been very well maintained, would be my guess. Again, the key, as I said, if you're going to buy a used one, if you can buy it from someone who's got all the oil change records, and they're all done within, say 10,000 kilometres, they've all used the right oil, that would be a pretty important thing to look for. Why don't we have a look at a few photos right now. Start with our car, there's the '06, nice red TDI Jetta. We'll go right to the cam shaft. This is the cam shaft that we pulled out of the engine. Now, if you're not used to looking at a cam shaft, it's kind of, this item I'm pointing at here, this is a cam lobe for one of the engine valves, and this lobe here which is unique to this engine, drives the fuel injection pump. You have eight, it's an eight valve engine, so there's a cam lobe for each intake and exhaust valve, so there's four per cylinder. If you look, this is a cam lobe that's in pretty good shape. It's got a nice pointed end to it, but if you look at this one here, you can see the end is not quite so pointy. Some of them are ... Some of the cam lobes are not pointing at us so you don't get a good view. You can see this one here is definitely rounded off. This is one of the really badly worn ones. This one ... It's got wear, but it's still in fairly decent shape. There's also a big gouge here where the fuel injection rocker rides, and all of these had that as well. Again, a lot of wear in these areas. We're going to do a couple more close ups of the cam. This is, again a close up. This is that right cam lobe that I pointed to. You can see it's got a pretty decent point on it. That's an example of a cam lobe that's in pretty good shape. This is a cam lobe that's pretty badly worn. You can see that sort of roundness and discolouration there. That one's again not very good. What happens is ... Actually, I'll show you one more thing. This is the lifter. This is what the cam shaft pushes against to push the valve. Now, it's a little hard to see in this photograph because of the angle, but ... Unfortunately I took it on my steel workbench so it doesn't stand out so much, but this lifter, although it's got a lot of little metal scratches on it, is actually still pretty flat. But it still, it would be ... It's still worn. But this one here is severely worn. It's actually dish shaped, and it's dished so bad there's actually a hole right in the middle. It's actually worn in the middle, right through the middle. The difference between this height and that is probably 3/16 to 1/4 inch, that's how much wear has taken place on this particular lifter. There are several of them like that. That explains all the noise. That basically explains why the engine had the clacking noise, because there was so much play between the cam and the valve, that it's clacking and making a bunch of noise. Plus, it's not opening the valve properly, so the compression is lower. It's not breathing enough air and exhausting properly. That causes all the performance issues with the engine.
Mark: Like always, using the right oil is essential.
Bernie: Yeah. It really comes down to the correct oil, change it regularly. You can't prevent everything. Even really good maintenance doesn't prevent your car from having problems like this, which can happen eventually, but it's a very good way to ... It's like eating healthy and exercising is not necessarily going to guarantee you a long life, but it will generally happen, as opposed to being, smoking and drinking and not exercising and laying on the couch all day.
Mark: There are a lot of generations of TDI engines. Is this one reliable, in your experience?
Bernie: It seems to be pretty good. I said we don't seem to work on a lot of these for some reason, maybe because it's not the most common years, but besides this issue it's been a pretty reliable engine. We haven't run into a lot of problems with it. I don't know that I'd necessarily not buy one of these as opposed to something newer, but the common rail design is a little simpler. There's a little more complexity in this engine because of that cam shaft driven injector. I'd say if you can skip this generation and go with something newer, you'd probably get something more reliable.
Mark: So there you go. If you're looking for service on your TDI Jetta in Vancouver, the guys to see are Pawlik Automotive. You can reach them at 604-327-7112. Book ahead, because they're busy.

Bernie: Thanks, Mark
Mark: Hi it’s Mark from Top Local, we’re here with Bernie Pawlik of Pawlik Automotive in Vancouver, 16 time winners of Best Auto Repair in Vancouver as voted by their customers. How’re you doing Bernie?
Bernie: Doing very well.
Mark: So we’re going to talk about a 2010 VW Golf and something about the automatic transmission fluid, whats going on with this vehicle?
Bernie: So this vehicle is actually equipped with a DSG transmission and the DSG stands for direct shift gearbox. It’s a sort of a hybrid between a standard transmission and an automatic, trying to incorporate the best of both worlds. I mean, the difference between the DSG versus a pure automatic or standard is it uses clutches, but there’s no clutch pedal, you just put it in drive like an automatic and away you go or you can shift it manually like a standard transmission, although it doesn’t have the same kind of stick. You either just push a lever back and forth from the gear shifter or they can be equipped with paddle shifters on most cars. So those are the differences. Now what’s different is the vehicle uses, the transmission uses these clutches, it actually uses two of them, it actually has two gearboxes built into one. To be honest, I’ve never seen the inside but I’m looking forward to the day when I do, probably pretty cool. But it basically, one transmission has first, third and fifth gear, the other will have second, fourth and sixth gear on a six speed. They have six and seven speed models and the reverse is on one of the two transmissions and so what’ll happen is it’ll already have pre-selected, say you’re starting off on the road, it’ll have already pre-selected second gear but it hasn’t engaged it yet. First gear is ready to go so as soon as you accelerate it engages the clutch in first gear and away you go and when it’s ready to shift into second gear, it’s already made the shift it just has to change the two clutches from one to the other, so the gears shifts are very fast and that’s the advantage. Apparently they can do upshifts in 8 milliseconds which is like eight thousands of a second, so that is like really really quick and that’s a lot quicker than an automatic can do. There’s also some advantages, the disadvantages of an automatic is you have your torque converter which creates some slippage, so there’s always a bit of slippage in an automatic transmission. So in a way an it’s an automatic, so it’s the best of both worlds being a standard and an automatic, and I’d say more complex. Although like I say, I haven’t seen the inside, but putting two transmissions into one with a hydraulically actuated clutches, it’s got to be expensive.
Mark: So is there something unique about the fluid that this kind of pretty complex piece of machinery is going to use to be able to shift in eight milliseconds and live with all that complexity and make it work properly for a long time?
Bernie: Absolutely, so Volkswagen has a scheduled service interval at 40,000 miles which I think is about 70,000 kilometres and they have that right in their maintenance schedule. In the past, a lot of auto manufacturers have been a little bit glib with their transmission fluid recommendations, like automatics, they say it’s filled for life, don’t worry about it which I know we’ve talked before which is a bunch of BS, but with this one, they’re very specific, change the fluid every 40,000 kilometres. So whey they say to do it, they’re pretty serious on it, they know stuff will go wrong. So it is a special fluid, you have to use a special, it doesn’t have to be by Volkswagen, but there is a very special fluid made for this transmission. The service also consists of replacing a filter, so you do the filter, you change the fluid and that is basically what needs to be done. So with anything, there’s lots of expensive parts inside, you don’t want it to wear out, you want it to work reliably for a long time.
Mark: So again, we had to switch computers this morning so we don’t have any pictures but this was a fluid replacement on a 2010 VW Golf - was there anything particular about this vehicle that you wanted to mention today?
Bernie: Well not really about the Golf, I think we just talked about the DSG service in general. Just a little history of background on the transmission, it came out in 2003 so you’ll find it on some models way back then and Volkswagen Audi uses it, so you’ll find it in various Volkswagen Audi models anywhere from the mid 2000’s right up until current. We just did a service last week on a 2015 GTI with DSG, so you know there’s, like I say it varies between car to car and it just made me realize I said 70,000 K’s, it’s actually 60,000 K’s. So since we’re in Canada, that’s the way we should be thinking, that’s the way our odometers work.
Mark: Yeah, and how are VW’s on the whole these days?
Bernie: I think they’re really good, I mean obviously they suffered quite a blow with their TDI and rightly so, I mean they were dishonest with the public, shouldn’t be that way when you’re selling the car and advertising it to be a certain way but I mean, there’s really nothing wrong with the TDI other than it puts out a lot more pollution that it’s supposed to. But I mean, the performance is good, the reliability of Volkswagen is really a lot better these days. Ten, fifteen years ago I wouldn’t of recommended one, like their automatic transmission had problem after problem, super expensive to repair and they died at a very young age. Those are just some of the things, electrical problems, power windows, these are the things we used to see but they seem to be quite reliable these days so I think they really upped their game and hopefully they’ll will survive their TDI and I’m sure they will and come through and make an honest product for the public. but the reliability is good.
Mark: How is the reliability on the DSG transmission given that you were maintaining it on a regular basis, changing the fluid every 60,000 kilometres regularly?
Bernie: Well to be honest, I don’t really know. We haven’t seen a bad one yet, I haven’t seen too many of these on a high mileage vehicle so I don’t really know what their longevity is, but I would say that based on the complexity, I mean that kind of stuff always scares me, you know when I think about what you could be spending on fixing something like this, I mean I would imagine a rebuild on the transmission like this has got to be six to ten thousand dollars. So changing fluid, the service is about, off the top of my head, it’s in the $300 range to do a service so it’s not particularly cheap but certainly not anything more than a modern automatic with synthetic fluid to do a proper flush service is cheaper. Every 60,000 kilometres is really cheap insurance. But certainly when things go wrong, there will be expensive repairs. Just change the fluid and you’ll get the best life out of it you can.

Our latest featured service is a repair on a 2005 VW Touareg for a ‘Hood Open’ warning light concern. The vehicle was brought to us by a client from Kitsilano, Vancouver.
Unusual repairs are a frequent motivating factor for writing these posts, and this vehicle certainly fit that criteria. Our featured 2005 VW Touareg came to the shop with several concerns and one was that the ‘hood open’ warning light would constantly display on the dash. While the warning light was annoying the fact that this prevented the windshield wipers from operating made this a safety concern.
This vehicle is designed with very close tolerances between the wiper arms and the hood; if the hood is open it will be scraped by the wipers. One of the functions of the hood switch is to disable the wipers if the hood is open.
Our diagnosis began with inspections of the hood switch and hood adjustment. All was good with these components. We then proceeded further with our tests where we found the problem to be caused be a microswitch on the side of the radio. Say what? A switch on the side of the radio causing the hood open warning to illuminate. Yes, surprisingly this was the case. Why this circuit is wired in such a way is truly baffling. To me, it represents the culmination of German engineering gone too far.
Nonetheless this was the cause of our concern and we found that by disabling the switch we were able to eliminate the incorrect hood open warning and restore the operation of the wipers. When diagnosing a modern vehicle you never know what strange things you may encounter.

Today’s featured service is oil pan replacement on a 2000 VW Jetta GLX, brought to us by a client from Steveston, Richmond.
This Jetta was towed to our shop with a very serious concern: there was no oil in the engine. The oil light had come on suddenly after the owner filled the gas tank at a gas station near their home. The car was then driven several blocks to their house. Checking the dipstick found no reading. Oil was added to the engine but it ran straight out the bottom.
Putting the car on our shop hoist revealed the cause: there was a hole in the engine oil pan.
At this point we had a dilemma on our hands and it required a conversation with our client. What we faced was a possibly, permanently damaged engine, however it might also be simply repaired by replacing the oil pan and adding oil. Knowing how long the engine had been run with the oil light on was crucial information. Apparently it had been several blocks. This is more than enough time to fatally wound an engine.
We decided that the best approach would be to first remove the oil pan and inspect. If we found no bits of metal in the pan then there would be a good chance that the engine might survive. Fortunately we found nothing but a few drops of oil in the bottom of the pan. The odds of renewed life for this engine were good.
Upon completion of repairs we fired up the engine. It started but ran very roughly and made a lot of noise. Given a few minutes the noise went away and the engine smoothed out: it sounded like a normal V6 VW engine. Our client was lucky.
We still don’t really know the extent of any possible damage and at some point this engine may fail.
What is important with this story is your oil light: if it comes on with your engine running shut off the engine immediately, or as soon as it is safe to do so. This is critical. Next determine the cause. First check your oil level and if it is low add oil 1 liter at a time until it reads properly on the dipstick. Once the level is confirmed good, restart the engine and if the light remains on tow in your vehicle for repairs.
The VW Jetta GLX V6 engine uses an aluminum oil pan and it can be broken very easily if it hits something. Bottoming out this car is not an option. Based on the easy availability of this part from numerous aftermarket sources this concern is obviously very common. If you own one of these vehicles, be careful.
