Mark: Hi, it's Mark from Top Local we’re here with Bernie Pawlik, the big bopper himself, Pawlik Automotive in Vancouver. 21 time winners of Best Auto Repair in Vancouver as voted by their customers. And we're talking cars. How are you doing Bernie?
Bernie Doing very well today.
Mark: So Jaguar S type, a 2001. So a little bit of an older vehicle with a ball joint replacement.
What was going on with this JAG?
Bernie: So this vehicle came to us, the owner also as an older Jaguar than this we do service on and he brought this one to us to do a maintenance service, full inspection. And we found that the left lower ball joint was severely loose, and I'd love to start that off with a video because as they say, a picture's worth a thousand words, video is probably worth even more.
So let's just get right into that. So this is the area you're going to want to be looking at here. I have the camera, I apologize. I was a little less than steady with the camera, but this is the thing that you're going to want to be watching. This is the left lower ball joint, right in this area here. So our technicians basically got the tire and he's just pushing it up and down on the hoist. Let’s play it again so you can get the full view of it. So there should be no play there whatsoever. Just one more time, because I just love finding stuff like this on a car.
Mark: So that's pretty, incredibly worn. Probably a half an inch or more of travel. How does that happen in a part that should have zero like literally zero travel?
Bernie: Yeah, it's just wear and tear. Just old age wear and tear. Nothing that the driver's done. I mean, you can't, I guess you were driving over really rough roads that probably shortens the life of your ball joints, but just generally, that's just normal wear and tear. I mean, this car is almost 20 years old now. Not very high mileage, but still, nonetheless, it's just age.
Mark: So if I were driving the car, would there be anything I would notice?
Bernie: You would probably notice some clunks when you go over bumps, you should notice some clunks or bangs. There might be a slight feel of the steering isn't quite as tight as it should be, but there's a lot of things that can cause that. And usually that happens gradually. So you don't really notice it, but it's entirely possible you may not notice anything.
Mark: And you mentioned already that this probably wasn't because of neglect, but can this happened because of neglect?
Bernie: I mean, the whole idea is to get your car inspected cause you never know how long it's going to be before you know, something like this happens. So the only, the only real neglect I would say is lack of inspection would cause that sort of thing. Other than that, if you routinely inspect the car, you're going to find things like this.
Mark: And when did this car last get inspected?
Bernie: Well, as far as we could tell, he brought a, this car had been serviced by a Jaguar dealership in Vancouver, and he brought the previous invoice, which I believe was about a year ago. And they'd done quite a bit of work on it, inspected the car thoroughly, they'd actually replace the right lower ball joint, the knuckle assembly, the knuckle assemblies with the ball joint bolts into, they replaced that. They replaced the lower control arm plus a number of other items during their service. So this car was inspected a year ago. So this is the kind of thing that, and obviously, if there was wear in this joint, they would have mentioned it at the time. So, clearly, you know and we often recommend an annual inspection on the vehicle. I think, you know, this just reinforces the idea to me just how important that is because you never know what's going to wear in a year.
Mark: So when you replace that, do you just replace a ball joint or other parts required?
Bernie: We, so there's a few ways you can replace it. You can actually buy the lower ball joint, but what we did was replace the ball joint with the knuckle and the knuckle actually attaches this to the upper ball joint. And it's where the wheel bearing bolts attaches and the lower ball joints, unfortunately, I forgot to take a picture of it. I thought I had, but the knuckles and assembly and the ball joints pressed into it. So it makes sense to do that because sometimes when you press the ball joints out, they don't press it and quite properly. And the last thing you want of course, is a ball joint to come loose from its housing because that defeats the whole purpose of the repairs. So we changed the knuckle along with it. So that's what was required to fix this one properly.
Mark: So the ball joint basically allows the wheel to go up and down, but also turn because it's got many more movements.
Bernie: Exactly. It allows the wheel to, you know when you turn the road wheels back and forth, it allows for that movement. Plus it allows the suspension to move up and down. So there's a lot of movement that takes place in this joint at various angles. And of course, if you hit a bump on a curve, it's moving at a different rate. So it does a lot of work.
Mark: And we're not even talking about the fact that the tires actually cant back and forth based on which corner you're going on as well.
Bernie: They do. And that's all part of the, you know, the way the steering geometry is designed in some vehicles have just one ball joint. Like a MacPherson strut suspension as a lower ball joint, and then the strut, which is the shock absorber all built in, holds the top of the suspension in place. So it's got less complexity, which is why it's popular and a lot of cars and even even high end cars use MacPherson struts. But then a lot of other vehicles you get, they all actually have four ball joints. They'll have two lower ones and two upper ones. And it's interesting when you look at the way the wheels move with those, you know, when you move the wheel back and forth, there's a lot of engineering that goes into the movement of those wheels, you know.
And then again it's for handling and road feel and that kind of thing.
Mark: So if one is bad, you normally replace all of them?
Bernie: No. The thing with suspension work is it's, well, a lot of car work, it's sort of, you have to evaluate how all the parts work together. So for instance, you know, with a ball joint, if one's worn, there's not really any reason that, and the other one's in perfect shape there's not really any reason to change the ball joint on the other side of the vehicle. It doesn’t, the parts are exactly the same dimension, so it doesn't change the geometry. Whereas if you change, say a shock absorber, it's kind of, there's a certain amount of wear that could be occurring in the other side that that won't allow the same cushioning. So you need to change both at the same time. Same with brakes. If you do one, you do both because it is very important that all components are exactly the same, you know for the braking. But for a ball joint, generally speaking, you know if it makes economic sense to change another one at the same time on the same side, for instance, then it's worth doing. But a lot of times, only one joint will wear. A lot of times if one joint where's the one on the other side won't wear for many years afterwards. So it's better just to change them again, you need, it needs to be evaluated as to the type of vehicle. But in the case of this JAG, we just replaced this lower ball joint. We know the right had been replaced a year ago and was tight. The upper ball joints were fine. There was no movement. So no reason to change those either.
Mark: So here's the question, a bit of a wildcard here. Why would I care? Like if this thing's going clunk, clunk and so what's the bad? Why would I care?
Bernie: That's a really good question. So you, why you would care is this, it's like an extreme safety hazard. I'm just gonna put this video, just go back to this video picture here. Behind this tin plate here is your brake rotor and your tires, kinda here out of the picture. So this joint breaks and this one's very close to breaking because the amount of play. This part here will just basically come apart and the wheel will fling out on an angle, flop out and yeah, you basically lose control of your vehicle. So. I've seen ball joints break fortunately almost every time they've surprisingly, they've actually just snapped in a parking lot maneuver. Which kind of sucks cause you have to, you know, get your car towed in but I have had one client who at a ball joint just break while they're driving, and he said it was a horrific experience. You know, if you're driving fast and you're going down a twisty road or on the edge of a cliff, you'll probably go over, you know, it's really dangerous. So this is one part you definitely don't want the break. So that's why you should care.
Mark: Your steering is important.
Bernie: Your steering is important. Absolutely and this is like a super critical part. You know there's some things like control arm bushings for instance. I mean, they wear and they cause clunks but they'll rarely, I can't imagine they ever get to the point of failing where you'd actually lose control of your steering. Whereas, you know, something like this, like a ball joint, this is a critical piece. It has to be in good shape. If you value your life and that of other people.
Mark: And how are S type Jags for reliability?
Bernie: They're pretty good. Let's just get in a couple of other pictures while we're here.
There's our S type, good shape for an old car. And a picture under the hood. I kind of jokingly call these Ford wires, kind of combining the word Ford and Jaguar because this is, you know, this is when a Ford owned Jaguar and they, you know, to me, I do say the odd bad thing about a Ford, but you know, Ford really made Jaguar much more reliable car. The money they infused into them kind of made them a little more mainstream and much more reliable. But when you look at a lot of these caps here, like for the power steering fluid, it looks the same as you'd find on a Ford. And then its engine is very, although it's interesting, a lot of parts aren't interchangeable, but this engine is very much a Ford V6 motor. This car is also available with a V8 as well, which is actually a pretty cool, nice high performance setup. But generally it's a pretty reliable car. There's are a few things that go wrong, but what we found with this vehicle is just sort of average wear and tear and maintenance and nothing really in particular that's bad about it. So, you know, I like them. They're not super high end, so they're not like an S type so the parts are a little more reasonable than some of the other, the XK models and that kind of thing.
Mark: So there you go. If you're looking for service for your Jaguar 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 because they're hopping busy. Or check out the website pawlikautomotive.com. The YouTube channel, Pawlik Auto Repair over 360-70, I don't know. I've lost count videos on there of all makes and models of cars and types of repairs, and of course, thank you so much for watching and listening to the podcast. We appreciate it. Thanks, Bernie.
Bernie: Thanks, Mark. Thanks for watching. Always a pleasure.
Mark: Hi, it's Mark Bossert from Top Local. We're here with Bernie Pawlik, Pawlik Automotive in Vancouver for the Pawlik automotive podcast. How are you doing this morning, Bernie?
Bernie: Doing very well.
Mark: So 20 years, best auto repair in Vancouver as voted by your customers and probably going to win a couple more, I bet, this year. Today's victim is a 2016 Jaguar XF. What was happening with this fine British luxury automobile?
Bernie: So this car came to our shop that was basically just due for a maintenance service. No concerns. Not a very old car, 2016, this is three years old at this point. I guess maybe four. I guess we're almost ready for the new model year, this being July. So three, four year old car basically due for a maintenance service.
Mark: So that's a B service. What's involved in a B service on a Jag?
Bernie: So B service, essentially there's two major services, there's the A and the B, the A is an oil change and a basic inspection. The B, which we did this time, is an oil and filter change and then a full vehicle inspection. So on this vehicle we would remove the wheels, inspect the brakes, do a full steering suspension inspection, inspect all the fluids, a full visual inspection under the hood, test the battery and charging system, pressure test the cooling system, do the full look over the vehicle. Scan the vehicle computer, see if there's any codes stored, usually clear them because often on these kind of cars, you'll get a number of codes stored for a variety of things that are not really relevant. But one or two systems pick up a little flaw. They set a code, store it, and we would just reset all that. So that's basically it.
Mark: So you follow a checklist when you're doing that, is that correct?
Bernie: Very, very thorough checklist. Yeah. Yeah. And it's based on our own checklist plus the manufacturer has a list of specific items, but generally speaking, from car to car, they're all the same. Unless of course you have an electric car, there's different fluid, there's less fluids to look at. And obviously you're not going to look at spark plugs on an electric, pure electric car. So there's different checklists of things for different cars. But for the most part, any gasoline or diesel powered vehicle will have the same checklist in general.
Mark: So were there any concerns with the vehicle?
Bernie: No. This car came up with a clean sheet, to use a British soccer term, nothing much found on it. It only has 12,000 kilometres. So the owner drives very little and four years old, really very little going on with the car. Next service, I think a brake fluid flush would be ideal. But which will be in a year. But other than that it's really, everything was in very good shape.
Mark: So anything interesting about this vehicle that you want to talk about?
Bernie: Yeah, I want to, well one thing I really like about this vehicle and we'll start a picture show in a minute is just what happens when you start the vehicle up. There's some pretty cool, if you've never been in a car, if you have one of these cars, you'll know what I'm talking about. But if you've never been in one of these cars, it's pretty neat when you press the start button, a few cool things happen. So we have a little video and of course, a few pictures. So we'll just start.
There's the a 2016 XF Jaguar right there. And let's just get in. There's a neat little video here I'll just share.
That's basically the start and stop procedure on the vehicle. So when you start it, you can see the gear shift knob. There's no actual handle anymore. It's just a button you rotate, pops up and down. And also, what I didn't show in this video is on the instrument panel on the dash, there are two vents, air vents, and they rotate open. So they're normally in a closed position. And when you press the start button again, these vents rotate to the open position. It's kind of cool and when you shut the car off, they kind of go down. So it's kind of neat. There's some neat little hideaway features on on this car.
Mark: So with those kind of interesting features, electrical features, did you want to show the engine and stuff too?
Bernie: Yeah, here's a view of the engine compartment. So I'll just talk about the engine for a second because I know you have a question to ask me about that, those neat features. But here's a view of the engine compartment with the plastic cover on the top. This is a three litre turbo, sorry, it's three litre supercharged engine, which is remarkably like the five litre engine you'll find in some other Jaguar models and Range Rovers.
And the engine, interestingly enough, looks pretty much like the, it looks pretty much like the five litre but everything's just a little shorter because as two less cylinders. But the supercharger, a lot of the piping, very, very similar in design. So it's kind of, it's neat when you see a manufacturer use that kind of thing, in a way where they take the same engine, they kind of scale it back and.
Mark: So they've scaled it from a V8 to a V6.
Bernie: Yeah. And it kind of reminds me, I don't really know the internal engineering of this, the internal engineering of the engine, but there's different things you have to do in a V6 motor. But Americans when they went from their V8's seem to be popular, they went down to V6's in the 1970s for fuel economy. They have a lot of engines, they kind of did this where they take a V8 and they basically chopped two cylinders off and they did it in kind of a rushed fashion and some of them didn't quite, the engine didn't quite fire properly, like odd fire V6's just by nature of the construction of the engine. Anyways, we're getting kind of technical here and but nonetheless, it's a neat way to do things and probably saves a lot of money in the long run.
Mark: All right, so the doodads, for the electronic doodads that, the first question that pops up in my mind is what happens when the battery goes dead? How do you start the car?
Bernie: Well you start the car with a... Okay, so you start the car and you can actually jump start the car. Like generally the battery, I believe on this vehicle's either located in the trunk or under one of the, probably in the trunk, usually hard to get at. A lot of, used to be a battery was always found under the hood of a car. But that doesn't happen much anymore. It's always remotely mounted somewhere, which is probably a good idea because you cram more under the hood. However, this big red positive symbol here, if you pull that cap off, you can actually attach a jumper cable to the positive and then just find a good ground somewhere else under the hood. Some vehicles actually have a ground tab and this one may have one. I don't see it readily available. But you can often even use something like a bolt from the top of the strut if you had to.
So that's how you jumpstart the battery. But if that doesn't work, then you might wonder, well what if everything is just completely dead and you can't even, I need to roll the vehicle to get it on a tow truck. There is a way and that is, with this engine cover off, there's a little piece right here, little lever. So this is a tip if you own one of these cars, there's a little lever right here. And if you pull on this lever, this will actually allow, that will actually shift the transmission into neutral so you can roll a car. So it'll actually lock up and you can do that. So there's your tip. If you own one of these cars, of course it has this little booklet picture here with a question mark.
Mark: An I, information. That's right. Yeah, I knew I was saying the wrong thing anyways. You know that you can refer to your owner's manuals is what they suggest here. So this is a good thing. Always good to keep your manual in your car, by the way. That's another tip because you never know when something comes up, you go, "Hey, what? How do I do that? Or what's supposed to happen here?" So keeping your owner's manual on your car is always a good thing to do. And that's your tip for the day.
Mark: So Jaguar XF, obviously this is a complex luxury vehicle so a lot of electrical parts, a lot of superchargers, et cetera. How are they for reliability?
Bernie: Well, they're pretty good. I often think Jaguar as having the reputation of needing to be in the shop for repairs every week. They used to be like that a long time ago, but when I think about it, they lived in a world of cars that weren't very reliable anyways. As time has gone by, cars have just got better and better and better and more reliable. But so to have Jaguars. These are pretty reliable cars but they do have a lot of expensive things to go wrong. And one thing that that we've seen on some of these, like a little slightly older models is cooling system problems, they'll develop coolant leaks. That's something that's really important to keep an eye on. We had someone a while ago, the water pump was leaking. They left it too long and destroyed their engine.
A while ago I was taking a little walk, we have a really nice walk over the bridge called Lion's Gate Bridge in Vancouver and I was walking across the bridge on a nice sunny day and I noticed the guy coming up the hill in a nice Jag of similar type to this. And I could see smoke coming out from under the car. I go that's very unusual that I could smell antifreeze in the air. So this person obviously had a coolant leak. And I think, I hope that guy fixes that car soon because otherwise he's going to cook his engine too.
So with regular maintenance, you can deal with these things. But of course if a low coolant warning light comes on, take it seriously. As much as we like the work of changing an engine, we really don't, because it's money that you could have, it's wasted money.
Mark: So there you go. If you're looking for service for your Jaguar in Vancouver, the guys to see are Pawlik Automotive. You can reach them at (604) 327-7112. Again, that's for people who live in Vancouver, British Columbia, Canada, (604) 327-7112 to book your appointment. Call to book because they're always busy, otherwise you're not going to get in. And of course thank you so much for listening to the podcast. There is more information on the website, pawlikautomotive.com. Hundreds of videos and articles on there. Our YouTube Channel, Pawlik Auto Repair, same story, close to 400 videos on there. All makes and models and types of problems and repairs and maintenance and advice about vehicles of all kinds. We love them all, mostly.
Bernie: Yep, we do.
Mark: Thanks, Bernie.
Bernie: Thanks, Mark. Thanks for watching.
Mark: Hi it’s Mark from Top Local Lead Generation, we’re here with Bernie Pawlik, Pawlik Automotive in Vancouver, 17 time winners of Best Auto Repair in Vancouver as voted by their customers. How’re you doing Bernie?
Bernie: I’m doing very well this morning.
Mark: So we’re going to talk about a classic, some people would say, another classic Jaguar XF from 2009, it had a thermostat problem, what was going on with this fine English sedan?
Bernie: Well our client came to us with a complaint of a coolant warning light on the dash, basically it was an overheating warning light. We’d actually had the car here a few months ago with a similar issue and it turned out the coolant overflow bottle which has a sensor in it, a level sensor was malfunctioning, so we replaced the bottle. Solved the issue and for a couple months it was working fine and then the same light came on. Although the conditions were different this time. It was only on after driving for about half an hour driving down the highway that the issue occurred.
Mark: So how did you go about diagnosing the problem?
Bernie: Well the first step with any coolant diagnosis is to make sure there’s coolant in the vehicle, so I verified that in fact the coolant level was full, it hadn’t lost any coolant, there were no leaks present anywhere. So the issue was either something internal in the engine was causing it likely run too hot or maybe that overflow bottle had a malfunction. Again so the first step basically hook up a scan tool which is something we can do on this vehicle, and access the data on the vehicle and see what the actual coolant temperature is. Drove the vehicle and it was pretty apparent, I didn’t have to drive a half an hour on the highway, it was pretty apparent just driving in the city, the temperature was creeping up pretty high. It’s normally, like the normal temperature on this vehicle should be under a hundred degrees Celsius. It was you know pretty quickly running up to a hundred, a hundred and two, a hundred and three slowly creeping up to a hundred and ten and you can hear the radiator fan running full blast the whole time. So that’s again, an indicator of a problem. So we brought it back to the shop and continued the diagnosis and I’ll share a couple of, well actually no, we’ll talk a little more then I’ll share some photos.
Mark: So what did you find that was wrong with the vehicle?
Bernie: Well after testing and looking at a few things further determined that the thermostat was the cause of the problem. The thermostat is supposed to open at a specified temperature, usually it’s around 95 degrees Celsius. It can be up or down five degrees above or below that number but that’s usually the right amount of time and as the temperature just kept creeping up, I figured it was either, the coolant’s full, it’s flowing, it’s mostly likely a defective thermostat and that was a place to start. When we took it apart we found the thermostat housing which is made of plastic, was broken apart which is not an untypical issue to find on these cars and that along with the bad thermostat was the cause of the problem.
So at this point I’ll share a few photos.
So here’s our fine 2009 Jaguar XF, very nice stylish looking four door sedan and this is a screen capture of our scan tool. It’s an Autologic scan tool, excellent for imported vehicles and there’s a number of items that we look at this. On this particular car it lists the temperatures that are running in the engine. So you can see fuel rail temperature, engine oil temperature, intake air, ambient air which is the outside temperature and this is the engine coolant temperature. Now I did this screen capture after we repaired it and everything was working properly and you can see it says 96 Celsius. This is pretty much where it sat the whole time when we did a long road test once the engine was warmed up but previous to doing this, as I said this number was creeping up to a hundred, a hundred and three, a hundred and five, a hundred and ten, so it kept going up. So this was a place where we get data and good data and information to look at. Back to a couple of the photos, here’s the thermostat housing, now initially you can, for this particular engine, it’s a V8 non-super charge, you can actually buy the thermostat separately but it was pretty apparent once we took it apart that the housing was damaged. Here’s a closer view of the inside of the housing. You can see this is a, this is supposed to be a nice round cylinder and you can see these rough edges, this is bits of plastic that have basically broken off and disintegrated and the the thermostat fits into this area. So it really affects the flow of the coolant through the thermostat. So the whole housing needed to be replaced. Not an untypical repair for these vehicles and Land Rovers use a similar engine as well and they do have problems also.
Mark: Alright, so this is a pretty, upper, special, fancy car is there any particular unique feature about this car that we should look at?
Bernie: It’s funny that you mention that because yeah there’s a couple of unique features about this car. I love the interior of the vehicle, when you get in there’s a push button start like a lot of newer vehicles have but is has a knob instead of a gearshift lever for the transmission, it actually has a knob that comes up, it’s a rotary knob and it actually lifts up out of the dash but the other really neat feature and I’ll just share a video here, so if you watch these dash vents as the engine’s starting, for some reason there’s no sound here, but when you shut the engine off which I did then these vents close. So that’s my kind of unique feature of this car. I think that’s pretty nifty, there’s four of them and they all pop open but strangely whenever I’ve worked on these cars, I go that’ll be interesting when something goes wrong with them and sure enough one of the vents which is not in that view, actually doesn’t close properly, it eventually closes, but it’s slow. So you know there’s with all that beauty and neat engineering, there’s extra stuff to go wrong but it’s a pretty cool feeling when you get the car and you push the button and all these things kind of pop up and move into position.
Mark: You’re showing your age Bernie, it’s like you talking about a 69 Corvette.
Bernie: Yeah I know, yeah exactly we talked about pop up stuff like hide away headlights awhile ago and now pop up dash vents.
Mark: So in the past, English vehicles had let’s say a, well terrible reputation for reliability, how is this age of Jaguar?
Bernie: These are good and yeah, you’re right, I mean older English cars are the kind of thing where you’d be having it in to the mechanic shop every week doing some tinkering or fixing it and these vehicles are really reliable. I mean, as I say, the thermostat problem is not uncommon and there’s a, it’s probably the worst thing about these cars is there’s a lot of plastic on them which just happens on a lot of European cars, not so much on Japanese, but a lot of European cars, there’s plastic in the cooling system so they seem to use a lot of it and it breaks. So that’s sort of one of the things that affects the reliability, but overall they are actually pretty good, I mean you can usually get in these cars and you can drive without much problem. So the engines are pretty good. They used to be problematic in the past, I mean as much as I often have had not great things to say about Ford’s ever since Ford took over Jaguar and Land Rover, it’s made them a lot better vehicles. So yes Ford’s aren’t that bad after all.
Mark: So there you go, if you have a Jaguar in Vancouver and you need some service, the guys to see are Pawlik Automotive. You can reach them at 604-327-7112 to book your appointment, you have to book ahead, they’re busy or check out the website pawlikautomotive.com or our YouTube channel Pawlik Automotive, you just have to search for it, you’ll find it, hundreds of videos on there over the last few years. Thanks Bernie.
Bernie: Thanks Mark
Mark: Hi, it’s Mark from Top Local, we’re here with Bernie Pawlik, Pawlik Automotive in Vancouver, Vancouver’s best auto service experience, 17 time winners of Best Auto Repair in Vancouver as voted by their customers. How you doing Bernie?
Bernie: Doing very well this morning.
Mark: So we’re going to talk about a little bit newer vehicle today, a 2010 Jaguar XF with the all too common check engine lamp problem. What was going on with this vehicle?
Bernie: So the vehicle was brought to us by our client, the check engine light was on on her dash and recently she had some bodywork done on the front of the vehicle, there was a small collision and had some body work done and a short time afterwards the check engine light came on. So she figured it was possibly related to that and she wanted us to see what was going on with it and see whether that was in fact the case. It wasn’t related to the accident but the check engine light was on.
Mark: What did you have to do to diagnose this?
Bernie: Well basically the first procedure we plug a diagnostic scan tool into the vehicle and see what trouble codes are stored. Every time a check engine light comes on, there’s a trouble code that’s stored in the vehicle or codes, there could be many of them depending on what faults there are, but there was one code in this case for a problem in the EVAP system and the EVAP system captures fuel vapour and prevents fuel vapours, gasoline vapours from escaping into the atmosphere which creates a lot of pollution and haze and a lot of those issues. So that’s why they have these complicated systems to keep gasoline fumes inside the vehicle.
Mark: So what other procedures, well that’s maybe a little, sounds a little more complicated. Don’t you just plug the scan tool and it tells you exactly what the problem is?
Bernie: No and a lot of people have that misconception that there’s a magic box you just plug in, tells you what it is, away you go, you fix that part and the car tells you what’s wrong. Not the case at all, I mean this magic box, the diagnostic scan tool will give trouble codes and information, it’ll give an explanation as to what the issue is, but it will not tell you what exactly is wrong with it. Now in this case, there was a circuit problem with one of the EVAP system valves and from there, well we can make an assumption, oh it’s this piece, let’s just change it, but really the proper way to diagnose it is having that information. It gives us an area to go, ok this is where the problem lies, from here we have to test the circuit. So we have to test the circuit from the computer back to the valve which is located in the, way in the rear of the vehicle, buried up above the differential. So those are the tests we need to do to verify whether the part is bad, whether there’s a wiring problem, whether the computer itself is bad because it can be any of those things.
Mark: So in other words basically, you just get an indicator of here’s where the issue might be, but then the issue could be caused by a bunch of different things failing or it could be upstream or even downstream of where the computer is telling you that it is.
Bernie: Exactly and it’s important to know some, you know with a lot of these trouble codes is whether the problem is being caused by the actual component or whether it’s being, something else that’s causing the component to read a fault. So like a lot of diagnostic systems, as cars get newer the codes are more and more specific as to where the problem lies but it’s still requires testing and verification to know and there are hundreds of things that can cause a check engine light to come on. So we can fix this problem this week, next week the light will come on because something else failed and you know, it’s kind of frustrating for an owner because you go, hey you just fixed that last week and it’s like well, it’s something else this time.
Mark: So what ended up being wrong with this Jag?
Bernie: So there’s a, so the EVAP system has an item called the charcoal canister and on the canister there’s an item called a leak detection pump, there’s a valve on the pump that opens and closes to atmospheric pressure, it’s a vent valve and basically the valve had failed. So that’s what was wrong and we found that as I mentioned through testing the circuits and making sure that everything was working fine but we actually verified that the problem was in the pump itself.
Mark: So that sounds pretty complicated to be honest with you. Was this a difficult part to replace?
Bernie: It is. It’s basically, Jaguar installed this part then they put the rear differential, it’s a rear wheel drive vehicle so the rear differential sits underneath it and there’s no room to even access the wiring connector for testing. So we have to do all the tests from the front of the vehicle but anyways, to get the component out, the rear differential has to come down, the exhaust system has to be removed, an axle shaft, there’s a lot of pieces that need to be removed. Once those are out, then the parts really easy to change. But its quite a few hours of worth of work to replace the piece.
Mark: Not exactly a Formula One car.
Bernie: No not as fast at taking tires on and off a Formula One that’s for sure.
Mark: So when a check engine light is on, is it always necessary to fix it?
Bernie: Well I would say, yes and no and it depends on what, why the light is on. So first of all you should fix it because you’ve got a warning light that’s telling you something’s wrong, now if you live somewhere where there’s emission testing and your vehicle needs to go in for a test, yes you’ll have to fix it because if the lights on, it’ll fail the test. We live in Vancouver, they don’t have emission testing any more so it doesn’t really matter from that point of view. My first question to anyone who’s got a check engine light on, is how is the vehicle performance? The performance is exactly, feels exactly normal then it’s probably ok not to fix it immediately but it’s alway worth having it scanned to see what the cause of the problem is. An EVAP problem is not going to affect your vehicle performance most, 99% of the time. It will create emission issues but so that’s up to your conscience as to how much you care about the environment. But if you have an engine misfire code or there’s some other codes that are a lot more serious, it’s important to fix them but those usually will be associated with engine performance issues. So key thing is get the code scanned by a professional, have some assess what it is and then you can decide what between yourself and your mechanic or your service provider, do I need to fix this right now? Depending on your budget, depending on if you have a holiday you need to go on, you know if this codes wasn’t fixed on this vehicle immediately it wouldn’t really affect the car right away but it’s a good idea to fix it and then of course if your check engine lights on for one problem you know of if something else happens you won’t know that there was another problem that’s occurred. It’s good to fix things as they happen because it’s, even though it costs money to fix it, it’s cheaper to fix them one by one that it is to wait till there’s 10 codes and go oh my god it’s like way too much money, I need to get rid of the car.
Mark: So that sounds like a really good plan actually. Get your check engine light checked to find out and get an idea of what the problem is and the you can decide whether you want to repair it to not.
Bernie: Yeah exactly that’s exactly the best way to do it.
Mark: So there you go, if your check engine lamp is on here in Vancouver the guys to call are Pawlik Automotive. You can reach them at 604-327-7112 to book an appointment, book ahead they’re busy, or call I already said that, you can check out their website pawlikautomotive.com. Thanks Bernie
Bernie: Thanks Mark
Our featured service is a 2001 Jaguar XKR Convertible Top Fluid Leak Repair, brought to us by a client from Kerrisdale, Vancouver.
One of the frequent failures on the beautiful Jaguar XKR convertible is rupturing of the hydraulic hoses to the convertible top latch. The leak becomes very evident to the owner as green oil leaks out of the top of the windshield/roof front attachment area above the console. The condition is known as the “green shower.” Once this occurs the top will no longer latch and must be moved up and down by hand.
So common is the issue that Jaguar sells a hose repair kit. It comes complete with newly designed lines and all the fittings to couple to the existing hoses down in the door pillar area.
While the repair kit is expensive and the job time consuming it is far easier and significantly less costly than changing the complete hoses to the rear of the vehicle where the hydraulic pump and valves are located.
To complete the service we cleaned the leaked fluid from inside the car. Considering how damaging an oil leak could be to the beautiful interior of this car, things cleaned up well. For the owner no evidence of the leak remained and the roof moved up and down as it was meant to.
Jaguar, for many years had a reputation as a finicky sports car, in the shop more frequently than on the road. With these Ford era Jaguars (1989 to 2008) the cars have become very reliable. As with most fancy European cars, their value slides precipitously and many models can be purchased used for a bargain price. The downside is that repairs can be expensive but if you’re prepared for that, you can drive a very luxurious vehicle for a fraction of the price of a new model.

Today’s featured service is Fuel Pump Replacement on a 2009 Jaguar XF, brought to us by a client from West End, Vancouver.
This beautiful 2009 Jaguar XF suffered from a stumbling engine and no acceleration when the fuel tank level was low and the car was cornered hard. Connecting diagnostic equipment confirmed that fuel pump pressure momentarily dropped to zero on sharp right turns. What we had was a fuel starvation issue.
The Jaguar XF uses a saddle tank: a design common to many cars. The tank spreads out across the vehicle under the rear seat, but must be made in such a way as to accommodate the driveshaft and exhaust system. To do so it becomes thin in the center and is deeper on both sides. This requires a system with either 2 fuel pumps or a main pump and a pick-up pump. Our Jaguar XF uses a rather unique version of the latter. The main fuel pump sits in the right tank in a bowl which is filled with fuel by a jet section pump located below the bowl and in the left tank.
In order to cure our Jaguar’s ailments we replaced the main fuel pump and the auxiliary assembly to the left tank. A road test involving some hard right turns, with our diagnostic equipment connected verified good fuel pressure at all times.
While fuel pump replacement often involves dropping the fuel tank, the Jaguar XF, like most saddle-tanked vehicles provides fuel pump access from inside the car. This is a great thing because removing saddle tanks is very labour intensive.
Fuel pump assemblies for 2009 Jaguar XF. Unit on left is the left tank assembly with fuel gauge sender and jet pump. The yellow arrows point to the jet pumps. The unit on the right is the right tank unit which contains the main pump inside the bowl assembly and indicated by red arrow. This unit also has a jet pump and fuel gauge sender
If you google fuel pump or fuel starvation concerns for this car you will find many results and there are recalls for some of these cars. This particular model was not one of those covered.
This 2009 Jaguar XF is a gorgeous car that looks great and performs well. The interior is luxurious, but perhaps the most interesting feature is the dash board air vents which ‘roll out’ when the key in turned on. While Jaguar cars have a poor reputation for reliability we find that those built since around the 2000 model year are good cars. The influence that Ford had on Jaguar was indeed positive.

Our latest featured repair is Ignition Coil Replacement on a 2004 Jaguar S-Type brought to us by a client from Tsawwassen, BC.
This 2004 Jaguar S-Type came in running very poorly with the check engine light illuminated. During our diagnosis we found several stored trouble codes: the most important were misfire codes. Five of the six cylinders had recorded a code. Further diagnosis and testing found two dead ignition coils along with several badly worn spark plugs.
The Jaguar S-Type comes with three engine options, this car being equipped with a 3 Liter V6 engine, by far the most common offering in this vehicle. Each cylinder is fitted with an ignition coil. With the already two dead coils, the worn spark plugs and the over 200,000 kilometers on the car the best line of repair was to replace all the spark plugs and ignition coils. Sure we would could have replaced only the known bad coils but when another one fails sometime down the road the vehicle will be back for more diagnosis and the overall cost and owner stress will be much higher.
Over the years the Jaguar S-Type has proven to be a decent, reliable car. We work on a lot of them and none require anything more than average repairs and maintenance. Around this era of Jaguar the company was owned by Ford and they did a lot to improve Jaguar cars. English cars were notorious for lack of reliability but Ford has clearly turned this around. The V6 engine used in the S-Type is essentially a Ford Duratec engine, a unit found in many Ford and Mazda vehicles.
