I have a 2002 A4 3.0 Quattro, and before that had a 2000 A4 2.8 Quattro. I just
took in for my second round of service with 18,500 miles.
While the sticker recommends lower, I keep the tire pressure at 38 psi and check
every couple weeks. Alignment on the car has seemed fine with no drift or
anything, and no abnormal driving conditions.
An issue that recently developed is abnormal wear on the front passenger side
tire, and is at the point where Audi service now tells me I need four new tires.
They also indicated the tires should be rotated every 5,000 miles, something
which had never recommended to me before. At the same time, they don't do tire
rotation when bringing the car in for routine service at 10K, 20K, etc.
I never had this problem with my 2000 A4, and had through 25K miles before I got
the 2002. I know at least one other person with an A6 Quattro and two others
with A4 Quattro's that have run into similar problems.
I wanted to see whether anyone here has run into the same problem, and if so,
whether Audi did anything to address the issue. A new set of tires at 18,500
miles seems way too soon, particularly when they do nothing in the way of tire
rotation for service, nor never made reference to having it done every 5,000
miles outside of their service plan.
