One problem related to brake disc rotor has been reported for the 1996 Audi A8. The most recently reported issues are listed below.
The front rotors on the 1998 Audi A8 warp after very short usage. We have complained to the dealer and they have resurfaced the rotors, and the problem quickly re-occurs. This causes mild to severe steering wheel oscillation under moderate braking, causing the driver to lift up on brakes. Audi dealer, and manufacturer should replace components with adequate disc such that there is no reoccurrence. Can cause extended stopping distances and steering errors.
