One problem related to brake disc rotor has been reported for the 2002 Audi S4. The most recently reported issues are listed below.
Ongoing complaint: brakes vibrate when stopping. Dealer reported front rotors warped and pads have chunks missing. Dealer replaced with part nos. 8d0-615-301-m front brake discs and 4b3-698-151 front brake pads/linings. The car was returned to me with the vibration still present. I contacted the dealer service advisor who advised me to drive a few hundred miles to see if the brakes bed and the vibration smoothes out.
