I have a 2010 Q5 S-line with 50k miles on it. I just replaced the tires (for the second time since the original set). I went with a Continental DWS given positive reviews from a family member with a Cayenne. Immediately upon leaving the tire store, I noticed that my car was pulling to the right. I tested this on streets, highway, etc at different speeds and got the same result --- if I let go of the wheel I veer into the right lane pretty quickly.
They rotated the front two tires, and it still pulled to the right. They ordered two more new front tires, and it still pulled to the right. They rotated the tires front to back, still pulls. An alignment check indicated everything is within specs. What gives???

 

Make sure if the tires are diractional they were mounted properly, make sure the brakes are not dragging on one side, and then take the car to a good alignment shop. They should be able to raod test the car and fix the problem. You could always go back to Audi if the warranty is still good.

 

when you let go of the steering wheel while the car slowly moves to the right does the steering wheel stay straight or does it have an angle?
