2004 Audi S4 Avant, Engine 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. 22 time winners of best auto repair in Vancouver as voted by their customers. And today we're talking about a little hot rod an Audi S4, 2004, that had some engine problems. What was going on with this vehicle Bernie? 

Bernie: This is a regular client of ours and, he was driving the vehicle all of a sudden the engine started running rough and he brought it straight to us for us to look at. So, yeah, basically rough running engine happened just suddenly. 

Mark: So this is an an S4, so this is the very hopped up version or the next to the most hopped up version of an Audi that you can get. So what engine is in this vehicle in 2004? 

Bernie: This one has a V8 engine, 4.2 litre V8 engine shoehorned, literally shoehorned into the engine compartment. I mean, the car is basically an A4 they've managed to cram a V8 engine into it. There are not many things that are easy to repair on this vehicle. Spark plugs are easy to replace. The intake manifold can come on and off easily. It was a few things, but most things are extremely difficult to service on this vehicle. 

Mark: So what testing and diagnosis did you perform? 

Bernie: So scan the vehicle computer, found some codes for engine misfire and multiple engine misfires. And then from there, it was a matter of, you know, based on how it was running to test the compression. We found that one of the cylinders, and I'll be honest with you I believe it was number two, but for some reason, the car was here for a long time. So one cylinder had no compression in it, so at that point we realized, okay, it's either the timing chain may have skipped the tooth and some valves got bent or something has happened that we've lost compression in that cylinder. The engine has got to come out. We've got to dismantle it and figure out what the next issue is.

Mark: So what was involved in repairing the vehicle? 

Bernie: Well, it's an awful lot. As I mentioned, the engine's shoehorned in. Taking the cylinder heads off is impossible, but cylinder heads are the thing that we need to take off to see when there is piston damage or valve damage, or what's caused the no compression.

So, in order to remove the engine, it's typical on Audi's when we need to do a lot of repairs, the front bumper assembly, and radiators have to come off. A lot of times you can put it in a service position, but we need to take everything off because we're taking everything out. The engine and transmission and subframe are dropped down below the vehicle.

It's many hours of work for a move everything. But once that's done, then the engine and transmission can be separated again, quite an elaborate job on this thing. You know, everything is fitted together so precisely. There's very little room for anything. So that was our next step.

We pulled the engine and then from there, proceeded to remove the cylinder heads again, extremely involved amount of work, to get the heads off because this engine has a very elaborate timing chain mechanism, which you'll see in some pictures that I'll show you. But once we get the heads off and we found, our problem, and that was one of the valves had dropped slightly due to a broken valve spring.

And, that's basically what caused our problem. The valve spring broke. The valve dropped and lost compression and it got slightly bent. Fortunately for the customer, that's all that happened. He brought it in soon enough and there wasn't any further damage. Let's just go into some pictures right now because that shows a lot.

So this is on the left bank of the engine, second cylinder from the front. You can see a mark here. This is one of the intake valves is tapped, just tapped the piston. Fortunately no further damage happened otherwise it would have required a complete engine overhaul or replacement.

Here's a view of the cylinder heads. These are five valve engines. There's three intake valve, two exhaust valves, nicely circling the spark plug. And this of course was the valve had the broken spring. So as part of the repair, we sent the vehicle to the machine shop for a full cylinder head overhaul, and they replaced all the valve springs because you never know if one breaks when's the next one going to go. So that's what we did for that particular part of it. So these are the heads basically reconditioned and resurfaced and ready to be installed. 

So as far as other issues, problematic areas of this engine we can get into next. Timing chains, I mentioned they're very elaborate. And, I'll just show a picture, this is a partial view of the timing chains, these are at the back of the engine, between the engine and the transmission.

Now this there's only a partial view. And this, you know, when I see these pictures, actually I'll just, we'll just cut to the full view because it's really mind blowing. This is the timing chain assembly on this vehicle. There are one, two, three, four timing chains, just an array of guides, tensioners on each chain. And guide failure is very common on these engines and so hence timing chain failures. And on this engine, we replaced all the guides and the tensioners, the, actual chains themselves don't tend to wear, but the guides do, and once they fail, they're, you know, the plastic pieces, they eventually chip or break and, you know, because of timing chain failure.

So you can see if you just take a moment, I'll just leave this picture up for a while and just look at all the things that are driven. So this is the crankshaft here, which drives this assembly here. This is an accessory drive assembly. And I'll show you a view of what that drives afterwards. It drives the air conditioning compressor from this unit here. So this is again, exceptionally complicated. And when I look at it, I go, I mean, let's put an electric motor in. I mean, it's just, you know, one rotating shaft versus like these zillions of pieces. I mean, it's amazing how well this works, but there's just so many moving parts to go wrong.

Anyways, so this is a common problematic area on this engine, the timing chain. And if you do have one of these with the V8, they will give you a problem at some point in time.

Mark: Yeah, that's a lot of plastic with a lot of friction and a lot of heat on it. 

Bernie: It really is. And you know, when people, you know, don't change their oil regularly, you know, get kind of lazy, it's just, you're just asking for trouble. Even if you do all your oil changes on time, they'll probably still be a problem that develops just because of the type of engine. But anything you can do to keep it lasting longer is so critical and so important. So, you know, skimping on a lot of changes will wear these plastic bits and pieces out way faster. So it's just so important to do them on time or earlier. 

So, couple of other issues we found with this engine. As we took it apart, we noted a bit of fluid seepage coming out between a couple of seals. So this is a view of the front of the engine reassemble. And you can see here, there's a case casing here. There's a lower oil pan casing. Again, you know, it's like exceptionally complicated machinery. Casing here, casing there, this goes all the way around. This is basically the main engine bearing casing. What we found, looking at the side of the engine. I don't have a picture of a before picture, but there was some, you could see some coolant seepage, very minimal, but nonetheless this engine was out, it was time to really, it was either do it properly or, with, you know, great extra expense. But at a later date, you'd have to pull everything back out that we already pulled out to do this. So it made much more sense to tackle this. So here's a view by the way, I mentioned the accessory drive from the timing chain. This is the air conditioning compressor, which is driven by a shaft from the timing chain with a nice little CV type joint coupling. And so again, like more complexity. 

And here's a bottom of our engine. So this is before we removed the main bearing case, we can see some seals here that were leaking. And then if we look further down into the engine, this is what the main bearing case cover off. Again you can see more O-rings and seals as one here, one here, one here. You can see the seals kind of starting to fester, bubble. So these were all replaced and, you know, a lot of extra labor and work. There's special sealant around all these other areas and the O-rings, of course needed to be replaced.

This is a closer view of the upper case. This is the main bearing case, I guess you'd call it. And again, the number of seals here, I've just put arrows pointing to all of these seals and O-rings. All places for leaks to happen and they were all starting to leak. So in 2004, this vehicle's now 16 years old. So this is the kind of time where all these things start to go. And I think that pretty much concludes the picture show.

Mark: Okay, this sounds like an enormous job. And with all that time, it's going to be expensive. So was it worth doing it on this car? 

Bernie: Well, the owner likes the car, he loves his vehicle. So for him it was worth it. I don't know for everybody, whether it is, it really depends on how much you liked the car. Yeah, that's really, what it comes down to. How you value the car. Some people are really about Hey, you know, this car's worth X amount of dollars. I'm not spending any more than that, or I'm not spending half the value of the car. People have their formulas. Other people are like, you know, whatever, I love this car. I don't care what it costs to fix it. So it wasn't that he didn't care, but you know, it was, he was committed to fixing this one. 

Mark: And how did the Audi run after all this repairing work was done? 

Yeah really awesome. Yeah. Ran really well. Nice, smooth running machine and should be, you know, fingers crossed, there should be no fluid leaks. And certainly from any of the parts that we replaced and resealed, you know, those are all things that are good, preventative measures and maintenance for the future.

And a lot of power from a normally aspirated engine, but a relatively huge engine in a small vehicle, basically. 

Bernie: It is. And I mean, it's a beautiful engine. You can see the five valves, you know, the valve timing gear. I mean, it's really well built. It's only a 4.2 litre, which is not that big, but it's still, you know, compared to the normal 2 litre turbo that would come in the car, it's a really nice instant response power machine. It's really fun to drive and all wheel drive in a wagon. You can haul, your kids around and, you know, have a nice little sports car and sort of some bikes on the roof.  It's a practical sports machine. 

Mark: So is this, after all that said and done, is this a vehicle you would recommend for someone to buy?

Bernie: Well, I'd say with great deal of caution. One thing I was going to mention, you know, is that in the same week that this customer came in, we had another client who had just bought one of these cars, love the car. He just bought one and came and had it towed in. He was on a road trip and the engine basically conked out on him, towed it in. We looked at it and I think the same thing happened to his engine. Only he was probably going at highway speeds and, it just, as far as we got with the diagnostic, we pull one spark plug out of a cylinder and a whole electrode on the end was just pounded right off. So I believe what happened for this particular engine is a valve spring probably broke as well and, dropped the valve into the engine and, you know, just bent everything up.

So for him, there was a little more work you involved in terms of replacing, well replacing it with a used engine was what we came up with, but he chose to have someone else to do the work on it. But again is  it worth it? You know it really depends on the individual. I think if you're going to buy any of these Audi V8s, you know, there's a few cautions to look at. Things like, timing chain failure is common. You know, those timing chain guides fail. Also now, you know, having had two vehicles in a week with probable valve spring failure, is that looks to be like another common problem as the engine ages. So I think it's something to keep in mind. 

I think with any car, you know, if you buying anything fancy, just expect that, you know, something or anything could go wrong and it could be expensive to fix. But there's some engines that clearly have a better track record over time and are built more robustly. I think this engine is not quite as tough as it could be and it's exceptionally complicated. So, that's something to keep in mind, but if you love this car, you know, it's your dream, buy it.

2014 Audi R8, Maintenance Service

Mark: Good morning. It's Mark Bossert at Top Local here with Bernie Pawlik of Pawlik Automotive, and this is the Pawlik Automotive podcast and video series, and we're talking cars. How are you doing this morning, Bernie?

Bernie: Doing well.

Mark: So, we're talking about a bit of an exotic car today, a 2014 Audi R8 that had a maintenance schedule. What was going on with this vehicle?

Bernie: Yeah, this vehicle just came to us for some routine maintenance service. It had about 24,000 kilometres, and we did an inspection. It needed an oil change and some air filters, and that was kind of all the car needed at the moment, but yeah.

Mark: Basically it had just been aging in a garage. Did you find any issues with it?

Bernie: No. Really, besides the air filters were dirty and obviously hadn't been replaced, yeah, there was not much really wrong with it. As far as mileage, it's pretty low. Not that there aren't things that do start happening to these cars, but as I say time is often as much of a car killer as mileage. Killer's isn't really the right word, but you know, it ages the car and it requires service. But in this case, nothing was needed. It was in good shape.

Mark: What's involved in an oil change on this vehicle?

Bernie: Well, they're a little more time consuming than your average vehicle. It uses a dry sump oil system, and I could explain that in a couple of minutes, but why don't we just get into a couple of pictures right now?

And you can see our R8 there sitting in the shop. The same platform as Lamborghini Gallardo. So you get get a bit of Lambo for the price of an Audi, which is kinda cool.

And what else we got here? We have one more picture, which is my favourite part. You know what's neat about this car is it's got that, if you ever look at these cars, it has that sloped back, I call it a trunk, it's not. It's a mid-engine car, and so you can see the engine on display through a glass cover, which is a really cool design feature.

But once things are removed, I mean, you can see there's two quite dirty air filters here. There's a big box that they're encased in, so they need to be replaced. You know, it's just a beautiful work of engineering, this engine. Really nice looking, very pleasing to look at. What can I say?

I was saying it has a dry sump oil system, and so that involves a little more work in terms of changing the oil. There's a number of oil drain plugs that need to be removed, not just one like a standard oil pan would have, but there are several that need to be removed, plus the filters kind of buried. That's kind of it. So it takes a little more time to change the oil, and of course the air filters are hidden away in a big box, so more time, but they don't need to be serviced too often.

Mark: So with a dry sump system, how does that work?

Bernie: So dry sump is basically, well like I guess as opposed to a wet sump is like a standard oil pan in a car. A standard car will have an oil pan where all the oil drains in this catch pan in the bottom of the engine, which will hold anywhere from four to maybe eight litres of oil depending on the engine, and a dry sump doesn't hold that oil in the bottom. It basically has a pump that sucks that oil, so the pan is essentially flat. The oil's sucked and it's stored in a separate tank in a different location, and the advantage to that is that you can pump the oil in and it doesn't ... It can be ... Well I guess, when you're driving really fast and you're going around the corner, the oil sloshes around and so there's a possibility that you could actually starve the engine for oil, so in some of your racing applications, all those kind of engines have dry sumps.

In the case of this Audi though, another reason it needs a dry sump is because the pan of course will stick down a lot, and this is a very low riding car, so to keep the centre of gravity low without having the oil pan there, you can actually mount the engine lower and put all the heavy parts, the weight down low where you want it for better handling. So, that's another reason for it as well.

I think I explained that. Is there anything else I missed about dry sump? I think that kind of explains it all.

Mark: That's pretty good. So, what's the recommended service interval on this car?

Bernie: Well, the first oil service, it's basically an annual service. So every 12 months the vehicles should be serviced, oil changed, and the vehicle inspection done. As far as mileage, every 10,000 miles or 15,000 kilometres is kind of the recommended, except for the first service is 8,000 miles, but then after that 15 ... Sorry, 8,000 kilometres, then after that it's 15,000 k's after that, or 12 months, whichever comes first.

Now if you only driven a thousand kilometres, I would assert you could probably go a couple of years between oil changes because it's not going to deteriorate or get contaminated that quickly. It's not necessarily a good thing to change oil too often either.

Mark: No, you're just wasting resources.

Bernie: Wasting resources, but there's also ... I'm not an expert on oil, but what I've read is that there are certain additives to oil that can actually poison catalytic converters. You change it too often, it gets phosphorus or something in in the oil. I could well be wrong about that, but if you were to change your oil too often it can actually poison your catalytic converter because this item gets burned off as time goes by, and too much of it will wreck your catalytic converter, so.

Not something we see very often, because most people don't change their oil too often, but it's something that I'm kind of cognizant of.

Mark: Sure. So this is obviously a very high performance semi racing vehicle. How reliable is it?

Bernie: Really reliable. I mean, I think the neat thing about now Audi R8 is that if you want to get into it, I mean it's essentially a Lamborghini Gallardo. This is a V8 model, so it's kind of tuned down a little bit, because I believe the Lambo's all have V10s, and of course the Audi R8's are available with a V10 as well. But I mean, the car goes really well. It's got like a 420 something horsepower in a 3,500 pound little rocket. It's was a pretty good moving car. I mean, they're very reliable. I mean yeah, they're going to be more expensive to fix than your average, like an Audi A4, but for the kind of car it is, it's a really good bargain and you can get them used for a good price. I mean, even new, they're well priced. I think if this is the kind of car you want, this is a great vehicle to own.

Mark: So, if you're looking for service for your R8 or any Audi in Vancouver, the guys to see are Pawlik Automotive. You can reach them at (604) 327-7112 to book your appointment. You have to call and book ahead. They're always busy.

How Reliable Are Audi Vehicles

Mark: Hi, it's Mark Bossert, producer of the Pawlik Automotive Podcast and video series. We're here with Bernie Pawlik, Pawlik Automotive in Vancouver, 20 time winners, Best AutoRepair in Vancouver as voted by their customers and of course today we're talking cars. How you doing Bernie?

Bernie: Doing very well this morning.

Mark: So, Audi. We're going to talk about the Audi, how a reliable are Audi vehicles?

Bernie: Well generally I'd say they're quite reliable, but they do need a fair number of repairs and service over time. There's a couple of models that are probably a little more problematic than others, but generally I mean, they're a very nicely built car and I tend to think of reliability as can I go out and start my car and will it drive me to where I want to go and generally Audi's are really good in that department, but they do have a number of problems and issues that come up from time to time, some more common than others.

Mark: So what are some of those problems that you see with them?

Bernie: Well why don't we start and sort of break the car down into different areas and sort of look at the reliability of each piece because there's a number of factors. We can start with the brakes and under the car, so I mean brakes generally are quite reliable on these vehicles but some of the larger SVU's like the Q7's, the breaks tend to wear quite quickly. It's a heavy vehicle, even though they have enormous brakes they do tend to wear quite fast. On the cars the life span is pretty normal, I think in 50 to 80,000 kilometre range and if you have one with a standard, you're going to get a lot more life out of the brakes then you would with an automatic. So brakes are good. Brake fluid flush is certainly a service that needs to be done on a regular basis, usually about every two years, but that's not really a reliability factor, so we've got the brakes there.

Mark: Steering and suspension?

Bernie: Yeah, steering and suspension. So for the steering and suspension, generally again, steering components are pretty reliable, the odd tie rod end will wear out here and there, again as the car gets older. Some control arm bushing issues, again these have some fairly complex suspensions in some of them and ball joint wear is also common in some of them. Again, this is over time, we're talking over five years, in the five to ten year old range of the car and older. So that's kind of steering and suspension, shocks and struts are generally pretty good but given you keep the vehicle long enough those kind of components will wear out over time.

Mark: What about the drive train?

Bernie: Drive trains are pretty reliable, but there are some transmission issues. Audi's use a variety of transmissions, they've got standards in a lot of vehicles, they've got that direct DSG, the direct gear shift box automatics, which apparently there's a lawsuit out around. We haven't seen any problems ourselves in our shop but there's certainly some issues going on with some of those. Clutch replacement we seem to do maybe a little more often than needed. I think things in the clutch, it's not so much wear but something will actually break or malfunction in the clutch and a lot of them use dual mass flywheel clutches, so they can be pretty expensive to fix.

Some standard transmission baring wear happens from time to time and the automatics generally are pretty reliable but the two wheel drive models use a CVT transmission and they can be very expensive to fix as well. But the all wheel drive systems are really quite reliable and I can't really think of anything we've ever done to fix an all wheel drive problem on an Audi, so they are also very good in terms of the way they distribute their all wheel drive in terms of driving, the way the distribution works to each wheel and providing the traction you need. But overall, that part of the drive train's pretty good, and I'm not saying transmissions are bad but there are probably more issues with them then a lot of cars.

Mark: What about the engine and cooling system?

Bernie: Engine and cooling system, that's kind of the big part and this is where Audi is probably, more issues happen than other things. I mean there are oil leaks that happen on a lot of different models, some of them can be pretty difficult to fix, there's an S4 model with a V8. Now the S4 it's like an A4 but they've actually crammed the V8 into this and it's a pretty spectacular vehicle to drive but when there's an oil leak in that, it's basically pull the engine out time to fix, so that can be very expensive to fix and all the engines do tend to develop oil leaks over time. The cooling systems, a lot of plastic parts, so they will develop leaks over time as well. Engines, generally the actual guts of the engine are pretty good with the exception of a couple models, like the Q5 comes to mind, there's a lot of oil consumption issues with those engines and to me, that's kind of a show stopper sort of problem.

Although, if you have to add a litre of oil every couple thousand kilometres it's kind of annoying but it's really not the end of the earth. Compared to the way cars used to be built a long time ago, that was not a huge amount of extra work but nowadays we kind of expect our cars to go a long ways without having to add any oil. But that to me is probably maybe of their more problematic engines, but generally the engines are pretty reliable, there are censors, things like oxygen censors that wear and of course the biggest thing that seems to go on in Audi's and Volkswagen's are ignition coils. But the good news about that is they're cheap. Audi's, sort of in the last decade or two, they've used the same ignition coil on their four cylinders, their V8's and their quite inexpensive, and generally easy to replace, they sort of pop out and they don't require a lot of labor to replace, so that's one edge that they've got, although they do tend to fail a little more frequently.

I mean, overall the engine's are good but there are some expensive things to do and timing belts are another area. So some engines have timing belts, some don't. A lot of them are chain driven, and it's important as an owner that you know which one it has because of course if it has a timing belt, you do need to replace that at the recommended interval. This just reminds in the early A4's when they came out, when they were really good, to me when they switched to an A4 that's really where Audi became a sort of decent vehicle, before that they were kind of a bit oddball and quirky but they kind of became a little more mainstream, and we had a client with one, the timing belt started making this clattering noise and they used more bizarre tensioning mechanism.

I can't really describe it here, but I looked at it and go, "This is supposed to be a highly engineered car, and it uses little ball socket joints on the tensioner," of course the replacement part was it was a regular style hydraulic oil filled tensioner and I don't know why they used that in the first place but every once in a while you find a strange thing like that but that was for the very early '97, '98 sort of model, so you'll never see that on anything newer, but as I say, if you got a timing belt, you need to know that it needs to be done. Timing belt is definitely a maintenance thing if the engine has one, and a lot of them don't.

Mark: Interior body and electrical system issues.

Bernie: Pretty good overall. I mean these are obviously nice, it's the luxury brand of Volkswagen, so there's a lot of fancier stuff but generally things seem to operate pretty well, we don't repair a lot of electrical issues with these cars. The power windows are pretty reliable, door locks, those kinds of things they're all pretty durable. With any car if you keep it long enough and it gets old enough something will happen, but it's not a problematic area for sure. Bulbs, on the models that have replaceable bulbs because this is starting to become a thing of the past with LED lights but those vehicles, bulbs tend to burn out. I had a client with a Q7, I remember every time he'd come in for service, it was at least a few times a year because he drove a lot, there would be five bulbs burnt out in the vehicle and of course the dash would be lit up like a Christmas tree morning, warning you that your lights are out. It's good having those warnings but it's kind of annoying because it always seems like there's something wrong with your car but electrically they're pretty good. Problems people might have would be more unusual than normal.

Mark: So, on all of these things, would you say that you see the S models, sort of the RS models a little more often just because they're more very high end, high performance range in the Audi series?

Bernie: We don't see a lot of RS models, I mean the RS's are even rarer. We do work on a few of them, the S's a little more, but I mean, more of the cars we work on are the regular. The lower end, the A line kind of models, but the S's are kind of the same thing that they just cram something a little more high performance in it and along with that comes more expensive repairs, so just so you know if you're going to buy that you're going to get a much fancier car, much faster, more fun to drive and more expensive to repair car, if that answers the question.

Mark: Absolutely. So, what maintenance service is required to keep all these Audi's running well?

Bernie: Well certainly regular service, so changing the oil as recommended and actually I'd suggest, not just as recommended by the manufacturer but more frequently because a lot of these, they're all synthetic oil changes. A lot of them they stretch the interval out along ways and it's better to do it probably ... We can discuss that kind of thing or you can discuss that with your service provider but more frequently than the manufacturer recommends I think is a good practice. Some other services, of course there's break fluid that should be flushed and engine coolant once in a while, there's other drivetrain fluids that need to be changed.

These aren't frequent services that need to be done they're in the 50 to 100,000 kilometre or 30 to 60,000 mile kind of range services. But fuel services are a really important thing, especially with a lot of newer generation Audi products, I say newer generation like last ten years even a little longer now use a direct fuel injection system and carbon deposits on valves can be a really big issue, so there's a cleaning service, it's like direct injection cleaning fuel injection cleaning service is highly recommended probably every 30,000 kilometres, 20,000 miles. It's really important to do that because if you get too much carbon build up on the valves, the engine can sometimes require disassembly to fix that, so this is a place you don't want to go and the services are not that difficult to do and not that expensive.

For the older models, before the GDI systems, the direct injection systems and Audi often calls them FSI or TFSI systems, a motor vac fuel injection type cleaning works really well to keep combustion deposits under control and keep the engine running well and of course, a part of good maintenance is using good quality gas and that doesn't mean necessarily premium gas as opposed to regular, it's good to use what's recommended, and a lot of Audi's will use premium because they're turbo charged performance engines, but using a top tier rated gas is good because they put the right additives in to keep the engine clean.

Mark: And how do you compare Audi with Mercedes, BMW and Porsche?

Bernie: Well, they're all kind of different. They all have their problems, they all have their issues. I'd say Audi's are a little more reliable and less problematic than BMW's. Maybe a little worse than Mercedes, it's kind of hard to say and it really depends from model to model, I mean they all have their goods, they all have their bads but they're all up there and I'd like to kind of call finicky German cars. They're in some ways, just a little bit overly complicated in many areas and a little more problematic but I mean, I'd say they're all kind of in the same realm.

Mark: And you're saying this as a Mercedes owner?

Bernie: Yeah.

Mark: And BMW owner.

Bernie: And a BMW owner, and I have to say I like the Mercedes better, I find it's a little more reliable, but it depends from model to model.

2002 Audi A6 2.7L Heater Hose & Auxiliary Water Pump Replacement

Mark: Hi, it's Mark Bossert here with the Pawlik Automotive Podcast. I'm the producer of our cast, our videos, our stuff. We do the websites. We do all kinds of stuff. We're here with Mr. Bernie Pawlik, Pawlik Automotive in Vancouver. How are you this morning, Bernie?

Bernie: I'm doing very well.

Mark: Kind of got lost there for a minute. We're gonna talk about a 2002 Audi A6. What was going on with this fine German automobile?

Bernie: This vehicle came to our shop. The owner was complaining of a loss of coolant. Not huge, but over time it was leaking coolant, so that was the client's complaint, coolant loss.

Mark: What tests did you do to find a loss of coolant?

Bernie: There's a couple ways we can test the cooling system. The way we generally ... Besides a visual inspection to verify a leak, which we can do under the car and on top, is a pressure test. What a pressure tester does, it actually puts the cooling system under pressure, same as what occurs when the engine actually warms up. The way a car cooling system works is it's a pressurized system. There's a sealed cap, which will blow off if the pressure exceeds a certain amount. Usually it's about 16 pounds per square inch, Psi. Some engines are a bit lower, some are a bit higher, but that's sort of the average. The pressure tester basically puts the ... We can put it under that level of pressure, and that'll force coolant out of the system. The thing with a coolant leak is, again, when the engine's cold, there's no pressure, so there may not be a leak. Sometimes there is a leak when there's no pressure, and then when it pressurizes, there's a leak. It's kind of odd the way cars work. Generally speaking, the more pressure you have, the easier the leak will occur. So we pressurize the system and then look for leaks. Sometimes it'll take a matter of seconds if it's a large leak. Other times, we've had vehicles where we pressurize it. An hour later, we look, can't see a leak. Leave the pressure tester on. Next morning, we come into the shop and there's drips on the floor and go, "Ah, that's where it is." Sometimes it's quick, sometimes it takes a while. There is one other test we do, and that is for combustion gas leakage if we suspect a cylinder head problem, but that wasn't the case in this vehicle. The only testing we did on this was a pressure test. 

Mark: And what did you find?

Bernie: What we found was there was a leak under the intake manifold around the back of the engine, which required further disassembly. What we did eventually find was the auxiliary water pump, which is located underneath the intake manifold, was leaking. That was the major cause of our leak. With Audis, there's so many hidden bits and pieces. This is true of a lot of cars nowadays. There's coolant pipes that run in various spots that are hidden under the intake manifold, under covers. There's a lot that often needs to be removed just to find a leak. But that's what we found on this car. Auxiliary water pump was leaking.

Mark: What was involved with repairing these components?

Bernie: A lot of disassembly. It's a lot of work. The other thing we did was replace the heater hoses as well. Let's just get into a bit of a picture show here.

Mark Bossert: Go to the pictures.

Bernie: Yes. The pictures. If you open the hood of this Audi A6, it's a V6 bi-turbo engine, which right away tells you there's a lot of stuff under the hood. There are two turbocharges hidden, one on each side buried way down, almost impossible to see.

This is basically the engine cover, the air intake pipe on the top, covers over the battery, plastic covers around the ... There's a lot of covers.

2002 Audi A6 2.7L Heater Hose & Auxiliary Water Pump Replacement

This is what we found once we removed the covers. The intake manifold, and that's the auxiliary water pump. This is located brilliantly, right in one of the hottest areas of the engine underneath the intake manifold. Obviously not a bad spot, because the car's a 2002 and it's 2018 right now, so that's a good 16 years of use and it's just started to leak. It possibly could be a better spot, but that's why it's there.

The other item I mentioned we replaced were the heater hoses, and I'll show you a picture in a minute. The heater hoses run from this area here. They run beside the battery, underneath the firewall here, through a tube, and they terminate somewhere way under here that you can't even see. Again, just for perspective, this is with the cover on. This is with everything removed. You can see there's a lot that's changed.

Now heater hoses. The heater hoses were not leaking, but we did this as a maintenance item. While we were working on the vehicle, we noted that the heater hoses were quite swollen. If you look, this is a brand new hose here, and this is the old hose here. Just take a minute to look at it. You can see where this clamp goes, how the rubber is much larger here. It's much larger in diameter here. By the way, that cut was just done for removal purposes. But you can see the whole hose itself is quite a lot larger. Wasn't leaking, but when a hose gets like this, the rubber's deteriorated really badly, and it's only a matter of time before it blows.

Mark: It looks like a good bratwurst.

Bernie: It does, exactly. Very good. Yeah, so anyhow, that's ... Yeah. That's our hose. Again, this is basically done as a preventative maintenance. Definitely extra labor to do it, but while we had the intake manifold off, made a lot of sense because it saved the client quite a few hours of labor, hence money.

Mark: These are complex vehicles, Audis. We've talked a lot about Audis, and they always are complex, so that means it's expensive and somewhat complicated to repair. Is it still worth it at this age?

Bernie: I think so. It largely depends on how the vehicle's maintained and who the owner is and how you take care of it. We've serviced this vehicle for quite a few years now. Previously, all the service they did on it was pretty up-to-date. When you keep a vehicle in good shape, it's just a matter of repairing the items as you go. Yes, they are expensive to repair. It's also an expensive car to replace. This particular model, the A6 with the 2.7 turbo was not a cheap model in its day. Again, calculating the cost of repairs, if you look at it over a period of a year and you think, "Well, say I spent $5,000 in a year." Most people think, "Oh, that's a lot of money." But you think a lease payment on a car like this, probably $1,000 a month. That puts you about $12,000 a year. Yes, you do have the benefit of a brand new car, but for about a third of the price, you can maintain an old one and take care of it. I think it's a good way to go. Either way with a car, it's money out the door whether you're making monthly payments, whether you're saving money and you buy the car cash, or whether you're repairing it and maintaining it. It's money out the door. You just gotta look and see how much it is.

Mark: That's one way to amortize or look at your car repair costs then, I guess.

Bernie: Yeah, exactly. I've had, interestingly, conversations with people where they ... "Oh, the car's worth $4,000. I don't wanna spend two on it 'cause that's half the value." I'm thinking, "What does that have to do with it?" It's really about looking at how much money's actually going out the door, 'cause no matter what you do, money is gonna have to go out the door. If you keep it in good shape and take care of it, it'll be better overall. I think it's important to just kinda calculate your overall costs. Of course if you buy a new car, which is fantastic to have, the insurance costs are higher on a newer car than an older one. I don't know. It's a matter of just crunching the numbers, looking at it, seeing if it works. Of course if your car's in the shop every month for a breakdown, that's not very good either. There comes a time and place where it's time to retire a car, but in the case of this Audi, the mileage is still fairly low. The owner takes pretty good care of it. They're able to part with it for a few days every once in a while to do some maintenance and repairs.

Mark: Speaking of the Audi A6, how was it after the repairs?

Bernie: Yeah, really awesome. No further coolant leaks. Again, with those heater hoses replaced, we prevented a further unexpected repair. We could've left those. But somewhere down the road those hoses are gonna burst, and it'll be driving down the highway or driving down the road somewhere where you're on your way to a meeting. This is what we like to do at our shop, is find those kind of things and prevent them from happening. That's the whole key to preventative maintenance is fixing it beforehand. And it's cheaper and less stressful.

2003 Audi A4 Brake Hose Repair

Mark: Hi, it’s Mark from Top Local, we’re here with Bernie Pawlik, Pawlik Automotive in Vancouver, 38 years of servicing and repairing vehicles in the Vancouver BC area and 18 time winners of Best Auto Repair in Vancouver. Eighteen times, voted by their customers as the best in Vancouver. How’re you doing Bernie?

Bernie: Doing very well.

Mark: So, we’re going to talk about a 2003 Audi A4, brake flex hose replacement. What was going on with this Audi?

Bernie: Well this vehicle came to our shop with a few concerns. Did an inspection on the vehicle and one of the things we found was, for a lack of bette term, a very pregnant brake hose and I’ll just get right into pictures because that will be the best way to actually show you what was going on with this vehicle. So here’s a quick view of the 03 A4 that we serviced, and we’ll just get into the brake hose which is right here. So there’s our Audi A4, 03 that we serviced and there is the brake hose. So this is the front left corner of the vehicle. You can see the McPherson strut here and that red arrow points to as I said a very pregnant brake hose. There’s a big humongous bulge in this brake hose. Shouldn’t be there. You can see the rubber, very continuous piece and actually, interesting, I didn’t even notice this on the vehicle, but there’s a very slight bulge here too which is also a problem as well. But this was the major issue on this hose and warranted immediate replacement. 

Mark: So I’m going to assume that this didn’t occur in the normal way that pregnancy occurred? What would cause this to happen?

Bernie: So a brake hose, I’ll just keep looking at this picture, a brake hose is basically a multi-layered rubber, it’s got rubber, it’s got you know it’s got fibrous, it’s got cords that run through the hose in different directions. It’s a very strong hose. This hose will handle at least 5000 psi pressure which you know, a brake system will undergo on a very high panic stop and we’ve seen, and actually tested on a gauge over 4000 psi and there’s probably some that put out even more. So this hose has to hold a lot of pressure. Now what likely happened with this hose, is there’s a, it probably developed a pin hole somewhere, like the rubber deteriorated somehow, developed a pin hole and the outer jacket of the hose is actually filled with brake fluid. So this is a pretty serious condition. As I mentioned, this other bulge here, which we didn’t really even notice, at least I didn’t when I took the picture, you know is also a serious condition, there’s deterioration there as well. So this hose is basically rotting itself from the inside out.

Mark: So what would happen if the hose was left un-repaired?

Bernie: Basically it would just blow and at the worst, usually these kind of things can often happen at the worst of times. You’d be driving down the road, you know, you hit the brake in a panic stop and the pedestrian runs out in front of you, you nail the brake hard and the hose just goes boom, and of course your brake pedal drops to the floor. Now a modern vehicle, you won’t loose all of your brakes but you’re going to lose at least half of your braking ability at a time you don’t want it to happen. So anything like a cracked brake hose, or sorry, a deteriorated brake hose, it’s a serious issue. You need to fix that.

Mark: Any other problems that happen with brake flex hoses?

Bernie: Well the other thing that happens a lot is they’ll crack. The rubber will crack. That’s probably the most common issue we find with them. As you look at the hose, especially where it meets the metal crimping’s at  the end, it’ll usually start developing cracks and that’s a good sign that hey, this hose is wearing out, it’s time to replace it. The other issue that happens with brake hoses that we see from time to time, is they’ll actually develop an internal blockage. So sometimes, if you have a vehicle that’s pulling to the left or to the right, and you hit the brake, that could be a front brake hose that’s plugged. A lot of times it’s a calliper that’s seized but it can also be a brake hose that’s plugged or if you go to bleed the brakes or flush the brake fluid and there’s absolutely no flow of brake fluid, it could be due to a blocked brake hose. So that happens from time to time. More common is these leaky hoses or cracks, cracks are the most common. Second would be these bulges and third would be the blockage. 

Mark: So I’m going to assume this isn’t just an Audi problem?

Bernie: No, it happens on all cars. They’re all, all the hoses are made from more or less the same materials and designs so it happens on all vehicles. 

Mark: And is there any correlation between how much somebody’s, you know, if you’re driving really fast a lot and hitting the brakes a lot, is it going to wear your brake hoses out faster?

Bernie: Really good question, I would say not. Really they just, they’re just a kind of part that wears over time and not really so much with brake usage. I don’t really, I’ve never really thought of brake hoses as any preventive maintenance, to say, you know really probably the only, the biggest killer might well be road salt because it deteriorates the metal crimps on the ends but overall they’re, they just wear and then they wear out when they do. You can’t really wreck them.

Mark: And that’s a regular check item when you guys to maintenance on any car?

Bernie: Oh absolutely. Yeah, whenever we do a maintenance service inspection like a, in our shop, a B service inspection, which is a full inspection or a brake inspection, we always look at the hoses very thoroughly. Something you should do you after the car’s a few years old, I mean, every year you should have that kind of level of things inspected because it could be good this year and  you know next year, it’s got a hole in it or even you know, six months down the road, things develop. So that’s why it’s good to have, important to have your vehicle inspected annually. 

Mark: So you work on a lot of Audi’s, how are the A4’s for reliability?

Bernie: Yeah, they’re pretty good, you know, I often say, probably sound like a broken record, most European cars, more things tend to go wrong, they cost a little more money to fix and maintain but overall, they’re quite good vehicles and you get a nicer ride than your sort of average car. So yeah, they’re quite good.

Mark: So there you go. If you’re looking for service for your Audi in Vancouver, the guys to see are Pawlik Automotive. You can reach them at 604-327-7112 to book your appointment. Check our their website, we’ve go five plus years of videos and now we’re adding Podcasts to the mix. Thanks Bernie

2004 Audi S4 V8 Drive Belt

Mark: Hi, it’s Mark from Top Local, we’re here with Bernie Pawlik, Pawlik Automotive in Vancouver, 18 time winners, 18 times, come on, Best Auto Repair in Vancouver as voted by their customers. How’re you doing Bernie?

Bernie: Doing very well this morning

Mark: So, Audi S4, these are a fun little vehicle, this is a 2004 with the V8 and there was a drive belt change. What was going on with this vehicle?

Bernie: Well the vehicle came to us with a couple of issues, actually the belt wasn’t the major one, it was, but we’ll talk about the belt anyways, but actually the major issue, it came in with some smoke coming out under the hood and the steering felt really stiff and it turned out that the power steering racket had a severe leak and also one of the hoses as well. So we replaced that, that was a very major amount of work in and of itself but we’re here to talk about the drive belt today. Basically, we’ll talk about the drive belt, there’s a bit of complexity involved in changing it.

Mark: I bet, this is a V8 crammed into basically into a vehicle designed for a 4 cylinder engine on the platform, how does that, how did that work?

Bernie: Well in order to get the, yeah, it’s very tightly fitted actually when you look down into the hood, you can barely see the drive belt, I mean, there’s no room to even put a tool on it. It’s wedged in extremely tightly, the clearance is probably like between the front place of the engine and the radiator, maybe an inch but no room to put any tools in.

Mark: So what needs to be done to get the belt replaced?

Bernie: Oh so that’s a really good question. So Audi has engineered in a solution and basically what you do is you remove the front bumper of the vehicle and then you, there’s several bolts that move the rad support forward and actually, the hoses, coolant hoses are all designed and anything attached, it’s designed to be flexed out a few inches so you can actually get in and access the belt area. So we’ll just share some photos at this point. Here’s our S4, it’s still a nice looking wagon, practical and certainly very peppy with that V8 engine in it. So there is a view looking down on, looking straight down into the engine compartment, there’s the pulley’s with the belt off, it’s not a large belt on this vehicle, it actually, this just drives the alternator and the AC compressor on the front, power steering is driven off the back of the engine which is another nightmare in and of itself. We won’t get into that one today but basically this is the actual, this is with the rad support moved forward so you can actually access the belt. I’ve got another photo to share here, this is a sort of view of the front, so the bumper’s off here and a kind of view looking at the engine but you can see even this doesn’t have a lot of clearance but there’s just enough to get in there.

Mark: so I there’s a lot of other services on this vehicle that need that same procedure, right?

Bernie: Well anything that requires work on the front of the engine will need that and a lot of Audi’s with timing belts, you actually have to do this too. So some of the V6 models with timing belts or even the 4 cylinders, you have to put it in the service position to pull the bumper off and slide it forward. I mean on this vehicle too, if you need to get the alternator out, you’ve got to get that. There’s a lot of things that need to be done to do it, so I mean, it adds a fair bit of work to every job but that’s what you get when you have an Audi.

Mark: So I’ve driven an S4 and ridden in the V8 model, I’ve even driven the V6 supercharged one, which is a later version of this, these things are little rockets, how are they for reliability?

Bernie: I’d call it a fair car, I mean you know, Audi’s are, there’s a few things that go wrong with these cars that are a little more than average and once they older of course, things will go wrong. The steering rack on this vehicle is a pretty expensive job based on the price of the part and there’s a lot of labour involved to remove it as well. So they’re complex vehicles when things do go wrong they cost a lot more to fix. They’re generally pretty reliable but some things that come to my mind on the various models and I’m not saying just specifically for the V8 but there are various models that there are things like crankcase breather issues which are common on a lot of European cars, ignition coils on Audi seem to die frequently and they’re actually one of the things that are pretty cheap to fix, the coils themselves are inexpensive and the labour is really easy. Yeah so, the ignition coils are mounted right on top of the engine on actually all Audi’s, the V8’s, the V6 is 4 cylinders and they remove extremely easily. So there’s one thing, even though they do fail, they’re extremely simple to replace, that’s a positive thing. But overall, I mean they’re nice cars you know, again and I say this with a lot of European, if you want to get a fancy European car you’ve just got to be prepared to spend more money to fix it.

Mark: And service becomes really important, regular

Bernie: Absolutely, I mean more important than any other car, it drives me crazy when I see someone who owns an expensive car like this, and they don’t change their oil regularly enough knowing what the cost of an engine replacement is on the car like this, you just don’t ever want to go there. So change your oil, do all the maintenance service, you just want to do anything extra, because extras will come along but just do whatever you can do to keep it maintained and lasting a long time. A lot of European car engines will last for 20, 30 years, you know there’s Mercedes out there even with 40 or 50 year old engines that are still running. So if you take really good care of your vehicle, it can last a long time.

How Reliable Are Audi Q7’S?

Mark: Hi, it’s Mark from Top Local, we’re here with Bernie Pawlik of Pawlik Automotive in Vancouver, we’re talking cars and we’re going to talk about how reliable the Audi Q7 is. How’re you doing this morning Bernie?

Bernie: Doing really well.

Mark: So Audi Q7, are they reliable?

Bernie: Yeah, they’re fairly reliable, I mean, you know to me I sometimes define reliability as can you get into your vehicle in the morning, will it start every time and the answer is of course, as long as you maintain your vehicle, yes they are quite reliable. There’s not too many surprise issues with these vehicles. They’re pretty good overall.

Mark: What items do you typically repair?

Bernie: Well, a lot of brakes, brakes don’t last very long in these vehicles, they’re also expensive to fix. Tires also wear out pretty quickly, I mean those are sort of the bulk of what we do on these vehicles. Also oil services, but because they use synthetic oil, they have a pretty large capacity oil pan, you don’t have to change the oil as frequently as you do on a sort of typical vehicle. But those are the main items that we do.

Mark: So why do brakes wear out so quickly?

Bernie: Well, that’s something that has puzzled me in a lot of these larger European sport utility vehicles, Porsche Cayenne’s, Audi Q7’s, Range Rover’s as well, they use a very large brake pad, a large brake rotor, you’d think that that should last a long time, but they’re heavy vehicles and the braking is very aggressive on them you know for safety reasons. So I think that’s part of what causes them to wear out so quickly but if you own one of these, expect you’re going to be doing a brake job every 30 to 50,000 kilometres and it’s always pad and rotors that wear every time.

Mark: Wow, and what about tires, why do they wear out so quickly?

Bernie: Again, it’s a sporty vehicle, they use a large tire, but they’re not, they’re more of a sports tire as opposed to being a long life truck tire. So again, it’s there for the ride, it’s there for the handling and so these tires just don’t last quite as long and rotating them regularly is critical because they start wearing funny and then they’re worn out. So again with tires you get 50,000 kilometres out of set you’d be lucky.

Mark: Ok, wow again. So what about engine concerns any of those?

Bernie: Overall the engines are pretty reliable, although we did speak at our last hangout about a rather expensive oil leak on a 4.2 litre V8. So things do happen but generally they’re pretty reliable. Some of the the concerns we do find are ignition coils wear out, this is pretty common on Audi’s. Fortunately, the coils are really cheap so I think Audi uses the same coils from a four cylinder to a V8, all over the place so they’re surprisingly inexpensive, but there is on a V8 for instance, there is 8 of them of once they start going you should change them all. Intake manifolds on the 4.2 litre, there’s a flapper inside the intake manifold that can wear out and break and that can cause the check engine light to come on. In extreme circumstances little bits and pieces can fall into the engine and jam up valves and can cause some pretty serious problems. So that’s another issue, but overall the engines are pretty reliable but they can be very expensive to fix. As again, if you look at our other previous hangout on the Audi oil leak situation. There’s a variety of engines in these vehicles too, there’s a 3.6 litre VR6 engine, 4.2 litre V8, gain runs really well, really good engine and then there’s a few different diesel options as well. The 3 litre diesel seems to be the most common, the turbo diesel, but there is a V8 as well and I’ve actually never seen this but I did a little research, there’s actually a V12 diesel that is available for three different model years. It’s got 493 horsepower and 738 foot pounds of torque. Now that would be an awesome ride. I’ve never actually seen one, I don’t know how many of them they made, but I don’t know that’s I’d even want to be around to repair it, I wouldn’t want to own that vehicle when it comes time to repair it but I thought that was pretty specification wise, pretty cool.

Mark: So are there any maintenance services that you would recommend as essential if you own one of these vehicles?

Bernie: Here’s a photo of a Q7 just to add a little flavour to our talk. Maintenance services, you know, regular oil changes are critical, the intervals on these vehicles are long, like a lot of European cars, I would shorten them up by, go 75% of the length, so if it’s 20,000 kilometres do the oil change at 15, if it’s 15 do it 10 to 12 thousand, better to do it sooner than later. Again if you look at our hangout with the oil leak and you look at the timing chains, the things in the back of the engine, you just don’t want these things to wear out. You don’t want, if you don’t want to be faced with a repair bill for something like that, so that’s critical. If you own a diesel you really need to drive that vehicle a lot, it needs to get warm, good highway drives are important. If you’re just doing a short little 5 kilometre commutes you’re really doing a disservice to that diesel. It’s going to cost you a lot of money to fix in the long run. So yeah, regular oil changes and regular services, rotate the tires, inspections every year or so depending on how much you drive. Those are the critical things.

Mark: This vehicle was, the platform was built with VW and Porsche and they have their own versions the Touareg and the Cayenne. How does the Q7 stack up against those?

Bernie: Well the Q7 and the Touareg are really quite similar. They use the same lines of engines although I believe the Touareg actually is available with a W12 V8 which is you know, again a ridiculously complicated engine but the Porsche I mean, it’s a similar vehicle but they’ve got their own drivetrains, they’ve got their own suspension systems, and their own engines and quite honestly, the earlier versions of the Cayenne were a disaster. The first V8 that Porsche had done since the 928 and they really botched it up for a few model years. I think the newer ones are better but those older ’05 to ’08 kind of era would be a vehicle to definitely avoid. So if I was going to choose any of that particular line, I’d go with the Audi because it’s got the nice luxury features and it’s a step up from the Volkswagen so if you’re going to have the problems with it, at least you’ve got the more luxurious vehicle. Although the Touareg is very nice.

Mark: So there you go, if you’re looking for service for your Audi Q7 or any Audi in Vancouver, the guys to see are Pawlik Automotive. You can reach them at 604-327-7112 or on their website Thanks Bernie

Bernie: Thanks Mark

2007 Audi Q7 – Engine Oil Leak Repair

Mark: Hi, it’s Mark from Top Local, we’re here with Bernie Pawlik, we’re going to talk cars. So we’re talking about a 2007 Audi Q7 that had an engine oil leak repair. How’re you going Bernie?

Bernie: I’m doing really well this morning.

Mark: So what was going on with this Audi SUV?

Bernie: Well this vehicle came to us with an engine oil leak and it was quite an oil leak when the engine, with the engine running there’d be, every minute there’d be a, maybe every couple minutes there’d be a drip on the ground, so it was a pretty substantial leak. Did a diagnostic and we found that the leak was coming from the upper engine oil pan.

Mark: Ok, that sounds like a pretty serious leaking problem, what was involved in fixing it?

Bernie: There’s a lot involved and actually you’re right, it is a pretty serious leak. Serious in terms of the complexity of the leak and also the complexity of the repair. The upper oil pan basically requires removing the engine from the vehicle and dismantling an awful lot of the engine just to make the oil pan off to make the repair.

Mark: Ok, that sounds a little extreme. Is the oil pan gasket a typical gasket that seals the entire bottom end of the vehicle?

Bernie: No, it’s a little different and this is kind of common on modern engine technology. The parts are aluminum so they fit the pan together with, usually a high quality, I wouldn’t call it silicone, but it’s like a silicone type sealer, it’s form of gasket material and then any areas of crucial oil flow, they’ll put O rings. So there’s 4 O rings and then the rest of it is this silicone type sealer, a special type sealer which they use in a number of gaskets, the timing chain covers, the lower oil pan is the same thing but that’s how most modern engines are sealed now a days. The typical big, huge gasket or well in the olden days or a cork gasket, those are long gone now.

Mark: So does it really need to be so complicated?

Bernie: Well I don’t know if it needs to be but it is. When you’re driving an Audi, people buy them because you want the performance, you want the fuel economy and of course, emissions on engines, it’s just created a storm of complication but the good news is you can hop in your vehicle still in cold, runs great, works perfectly, the performance cold and hot is the same, where if you go back 20 or 30 years ago with carbureted engines, you’d be stalling and stumbling until the engine warmed up. So not to mention the amount of pollutants you put out. So there’s a lot of complexity. I’m going to share some photos here, we’ve got lots of them to look at so, let’s start with, here’s our oil leak, you see that ok Mark? Perfect. Ok so this is a view of the bottom of the engine looking up, this area over here, this is the crankshaft pulley and the serpentine drive belt and right where the red arrow is pointing, that’s where our oil leak was coming from. So this assembly right here, this is the upper engine oil pan and down here’s the lower oil pan. The lower oil pan by the way can be replaced inside the vehicle but the upper is a much more deeply buried component let’s say. So that’s where our leak was. This is what we viewed in the engine once we pull the engine out, this is another view of, kind of head on, this is a seam of the upper oil pain right here and so that where, again you can see the leak. The oil pouring down out of here, down here, as the engine was running. So let’s look at the complexity. There’s the back view of the engine. These are the timing chains of the engine. I mean, this is like a really really complicated set up, a lot of bits and pieces. Fortunately for our client, everything seems to be in pretty good order but there are a lot of parts and pieces that can wear here, a lot of money. So basically here is the crankshaft, so this is where it all starts turning from. You’ve got chains here driving the oil pump drive, then you’ve got chains here, this is the main chain that drives the camshaft gears and then you’ve got chains that drive the camshafts and these are the variable valve timing phasers, there are solenoids up here. So there’s a lot that goes into this to make this engine rune like the beautiful engine it does, but as you can see, there’s a lot of complexity here. What else have we got here, there’s a view of the vehicle, to pull this engine out, you basically pull the whole front cradle out, the transmission, the transfer case and the engine so that’s the assembly sitting on jack stands after it’s removed and the body of the vehicle is sitting up above. Almost looks like a Ford 6 Litre type of jobs that we do. Now one common, oh so here’s our lower engine oil pan, so this is what the unit looks like cleaned up and mostly cleaned up and ready to be reinstalled. Very precise piece of machine, you know precision machine piece of equipment. And yeah, so now one area of problem on these Audi’s, these engines are fairly reliable but there’s one engine, one problem area and that is the intake manifold. They’re inside the intake manifold there are runners to change the airflow inside the intake manifold, again this is what gives the engine the performance that it has. There’s a set of runners here, right by the intake ports, there’s a set of runners here and then inside the manifold is a set of runners that change as well. There’s actuators over here which are electronically controlled and when we took this manifold out, there’s actually some broken pieces that fell out, fortunately they never fell into the engine, we were able to retrieve them, but these are, this is part of the flapper inside the manifold that’s broken. This is actually a fairly common breakage problem on these engines. Sometimes it can result in pieces actually falling into the engine and causing problems. So this is something we’ll have to address with this repair. It’s expensive, unfortunately you have to buy a complete manifold and the part can only be purchased from Audi. So there’s a view of the complexity, some of the things, one of the things that goes wrong, a couple of things and there we have it.

Mark: So looking at the back end of that engine, kind of reminded me of a throwback to looking at an old V12 Ferrari engine with dual overhead cams.

Bernie: Yeah, same complexity, you don’t need, you can have that same level of complexity even in a Kia nowadays.

Mark: So how are these vehicles overall?

Bernie: They’re pretty good, I mean they, it’s an Audi, it more expensive to maintain of course, things that that wear out faster than you’ll find in a lot of other cars, it’s big, uses a fair bit of fuel, very nice vehicle, overall pretty reliable but there are some areas of issues and we’re going to discuss that in a future hangout.

Mark: Alright, so we’ve been talking with Mr. Bernie Pawlik, Pawlik Automotive in Vancouver. If you need service on your Audi from experts who know what they’re doing, so Pawlik Automotive 604-327-7112 or check out their website Thank you
