Production Solution
Not applicable.
Service
1. Verify that the noise is coming from the front of the vehicle.
2. Remove the front wheels and front brake discs.
Tip: Place the brake disc on the brake disc hub (wheel contact surface) so that the friction surface is not
damaged during testing.
3. Check the sound of the brake discs according to the video located at:
https://audi-external.kzoplatform.com:443/swf/player/303 (Figure 1).
• If the sound of the brake discs matches Sound A in the video, the
brakes can stay on the vehicle.
• If the sound of the brake discs matches Sound B in the video, the
brake disc pins are loose and are the cause of the rattling noise.
Replace both front brake discs.
