Thanks kimbo, but if they're symmetric there really shouldn't be torque steer to one side specifically?

I guess I'm just confused as to why torque steer would always take the car in one direction as opposed to left or right depending on condition of the road.

The key factor in kimbo's very complete explanation is the how the axles aren't perfectly rigid. When torque is applied to it's inner side, the axle can't help but twist at the moment that torque is introduced resulting in a momentary reduction of the amount of torque that is applied to the wheel that it drives. Since one axle is shorter it tends to twist less than the other, longer axle which allows more of the engine's power to be used at that wheel. You mash the gas, both axles twist but one a little less than the other. That difference in applied power results in one wheel turning with slightly more force than the other and it tries to snap the wheel to one side or the other depending on which side has the longer axle.

Are your tire pressures good? Any chance you've got a sticking brake caliper anywhere?

Quick question here, so my 2007 CPO'd A4 is coming up on its 35k service (bought it at 30k), how much should I expect to pay for the service on the basic stuff, of course assuming that nothing major is damaged/broken.

Tire pressures seem good and even, I don't think I have a sticking caliper (I'm assuming I'd feel something different when braking if that were the case?). I don't know, I think this might be normal and I've never noticed it before.

If I point the car slightly to the left, for example, and step on the gas, it won't necessarily begin going off to the right but might continue to go to the left. Sometimes though it will start veering to the right either immediately or after going straight for a bit. I don't know, it's kind of hard to be sure about this because the road surfaces here are convex - if that makes sense? Like if you were to slice through the road you'd see that the surface isn't straight but curves down toward the right shoulder. Then again, it happens on highways too and they're not really made in the same way.

Anyway, I'm probably overthinking it. I can always go to the alignment shop and ask them to re-check everything. I have two brand new rear tires also, so that might have something to do with it?

Depending on where you are all the roads, some of the roads, or none of the roads may be angled in some way. It's a weather drainage thing and will affect how your tires wear as well. Some places will align your car with respect to this. I've never worried about drifting to a side unless it was a consistent issue.

The info about the parts software makes sense sadly. I ordered the iPod interface for the stock stereo in my car and it took them a couple times to get the right one because of confusing information in their database.

The last time I had a car aligned, I was told that they are ever so slightly set up to veer right. In the old days they used to be setup to compensate for the crown in the road, but since most roads are built properly these days that they set them just off center to the right so that you don't veer into oncoming traffic.

Services like oil changes/spark plugs/air filter/pollen filter replacement can vary in price a great deal from dealer to dealer and location to location. I can't remember what the 35k service entails on your 2007 but I think it might be the larger one that includes the stuff I mentioned above. Maybe post your location - another goon might be able to help out with a clearer answer.

Brake cables - I think the cables go for about $30 each and the book time is about 1.2 hours.

License plate lights - there's two versions of lights in your model year. One is like the internet says: just press down on a little tab at the top of the lens and pop the thing out. The second type is held in by 2 small philips head screws. The screw type is pretty obvious. Try pressing the lens inward while pushing on the lock tab.

I have a 2007 2-door GTI and want to replace the factory speakers. I'm wondering if anyone has any recommendations for speakers that require little to no modding. I know there will be some because VW loving riveted them in. I am keeping the factory head unit and getting a JL cleansweep along with a JL stealthbox for the trunk. No clue what I should be putting in the doors/back though.

Also, probably a stretch, but if anyone has any recommendations for reputable places in the Chicago area that could do an install like this, that would be awesome.

To get completely tedious, I think I should clarify that the suspension (control arms, steering knuckles, etc. -- those are symmetric. But the axles that take power from the transmission and send it to each wheel -- those are not the same length on the driver and passenger sides. The reason is that FWD transmissions are usually not packaged with the differential in the middle of the car. So one axle ends up being longer.

Got it, thanks for the explanation.

Here are the numbers for my alignment:

Front: Left

Camber (actual/specified range): -0.5 / -1.2 to -0.2
Caster (actual/specified range): 6.6 / 7.2 to 8.2
Toe (actual/specified range): 0.09 / 0.00 to 0.17
Turning angle diff: -1.70 to -1.03 (no actual # for this one)

Front: Right

Camber (actual/specified range): -0.9 / -1.2 to -0.2
Caster (actual/specified range): 6.7 / 7.2 to 8.2
Toe (actual/specified range): 0.10 / 0.00 to 0.17
Turning angle diff: -1.70 to -1.03 (no actual # for this one)

Front:

Cross Camber (actual/specified range): 0.3 / -0.5 to 0.5
Cross Caster (actual/specified range): -0.1 / -0.5 to 0.5
Total Toe (actual/specified range): 0.19 / 0.00 to 0.33

Rear: Left

Camber (actual/specified range): -1.9 / -2.3 to -1.3
Toe (actual/specified range): 0.09 / -0.02 to 0.19

Rear: Right

Camber (actual/specified range): -1.6 / -2.3 to -1.3
Toe (actual/specified range): 0.07 / -0.02 to 0.19

Rear:

Cross Camber (actual/specified range): -0.3 / -0.5 to 0.5
Total Toe (actual/specified range): 0.16 / -0.04 to 0.38
Thrust Angle (actual/specified range): 0.01 / -0.33 to 0.33

So the only numbers that are slightly off from specified range are front left and right caster (6.6 and 6.7 degrees respectively vs 7.2 to 8.2 range). This is from this morning, I took it to the shop, they put the car up on the machine and said everything is fine. Anyone with some cool alignment knowledge who can clarify for this dumb goon?

I am preparing to replace the pistons in my VW Rabbit 1.6l Diesel, I have to remove the ridge that has built up on it and it needs oversize pistons. How do I tell which pistons I have currently (I suspect they are OEM) without remeasuring the current cylinder bore? There is something stamped upon the pistons, but I cannot find any references for the markings

I am planning on replacing the pistons with the turbo pistons as I have installed a turbocharger.

It's probably within spec if the dealer isn't adjusting it. I don't know anything about multilink front suspension alignment and so can't speak for the GTI suspension, but on my dumb McStrut setup on my WRX, 0.5 degrees of caster in the RF suspension caused an enormous amount of darting under power, especially on slightly crowned roads.

Some cars are more sensitive to caster than others. You could talk to a local shop that does performance alignments to your spec and see what the tech has to say about it; he might have a pet setup or be able to determine exactly what part of the setup is causing the problem. You could also have them reset it exactly back to the way the alignment used to be before the dealer 'fixed' it and see if that makes the problem go away (albeit at the cost of accelerated tire wear.. obviously, the tech would need to be consulted for specific adjustments).

It's not the dealer doing the alignment in this case, it's a local tire/wheel shop. I'm also fairly sure that caster cannot be changed on these cars.

Caster is out of spec from what I can tell, but it's even for both wheels.. should I give the repair shop a call and ask them what might be causing it? From what I've found online it might be from suspension damage. I wonder if my tires are going to get ruined quicker from this.

I have had it kick in on areas with gravel or uneven surfaces. There is a light at an angle by work that it kicks in if I am giving it enough speed when the light turns green. Also have had it happen on wet leaves. Seems like it does a pretty good job at preventing you from skidding.

Are there any common reasons that the CEL would be on for an '06 A4 2.0T? Sometimes it goes away for a while, and then it'll be back on. Dealer has no idea whats up. It's got ~130,000km on it, timing belt was done recently, brakes were done over the summer, all regular maintenance has been done on schedule at the dealership. I believe its had the diverter valve? (DV?) replaced once. It doesn't seem down on power, feels like it handles fine, fuel mileage is no worse than normal. Its an automatic, and as nothing seems to be wrong my parents aren't inclined to spend a whole lot of money diagnosing it, however in Ontario thats an instant fail on the emissions test.

:) Yeah, I think it was wet leaves, the dudes with leafblowers weren't around due to rain so most small roads are covered with them. I don't really drive that fast when I'm just going to work, so TC kicking in on a slow corner surprised the poo poo out of me (I think it was both TC and XDS since I felt brakes clamping down too like someone stomping rapidly on the pedal).

I've had TC come on at lights too, but usually when I floor it or if the road is wet enough.

Try removing the oil filler cap while the engine is running (but don't leave it off for long - the car will run like crap and then stall). If it was difficult to remove then odds are you've got a failed/failing PCV valve. What's your local Audi dealer?

Called the shop today to follow up and the alignment guy said that having slightly lower than recommended caster on front wheels is normal, even for cars straight from factory. Don't know if that's true or not, but seems to be fine as long as it's even for both wheels I guess.

Local audi dealer is http://www.agincourtautohaus.com/ on Sheppard in Toronto. Will try the oil filler cap test later this afternoon.

E: Did the oil filler cap test -- how hard is normal? It was slightly more difficult to remove than when the car is off, but not by a lot. Do you have any recommendations on independent shops in Toronto, or other dealerships? Apparently this one has not been great in terms of the service department, but my parents are hesitant to take it anywhere that isn't recommended.

With the engine running you should have no trouble pulling the oil filler cap off once you've turned it. When the PCV starts to fail it becomes more and more difficult to remove the filler cap. I had an Eos that was so bad that I couldn't remove the cap with pliers and the engine had actually started to suck air past the crank main seal which made a horrible moaning sound.

I'd recommend Pfaff or Owasco in your area. I've been on course with a number of techs from both dealerships and they're very skilled. Of the 2 I would go to Pfaff - they're total pros with a lot of experience. If you're in the Kingston area you could drop by Kingston VW/Audi - they're a smaller dealer but they've got a couple of techs that have like 30 years of experience with the product.

Once turned it seems to be only slightly harder to remove the oil filler cap than when the car is off, so I guess it could be just starting to fail.

It looks like it'll get taken to Pfaff at some point, probably next week. Thanks for the recommendation!

If I pump the brake they go off. If I try lifting up the brake pedal then release it the lights go on, then if I pump them once they turn off. Seems like this is a sensor issue.

Look for diff seal leaks, weak exhaust flex pipes, bad wheel bearings, torn CV boots and play in the front suspension links. Overall these A4's are pretty tough and durable so they tend to survive well with good maintenance.

It's got to be the R. I'm not sure what they're trying to accomplish with it though, at 34.5K MSRP... A3 with quattro seems like a much better deal for the money.
