Two problems related to seats have been reported for the 2001 Audi S4. The most recently reported issues are listed below.
Driver seat began to rock. Currently rocks at a much greater distance, brought to the dealership and hey claim it is within the manufacturers specifications.
Rocking drivers seat, normal driving, man of average size 5'11 180lbs. Seat starts to move forward and back when braking, accelerating. Dealer has replaced the seat frame twice citing that it was broken. Now the seat is rocking again and they are now saying it's normal. It's not normal, why does the seat move back and forth? when they replaced the seat frames both times the seats felt good and stable, no rocking no moving, but they fail just months later.
