If the customer does not identify the sound as the sound of the parking brake being actuated, he or she may simply complain of hearing noises from the rear brakes. Ignition is switched off. Steering is locked. Park is selected. Parking brake is not engaged. If the electro-mechanical parking brake is not operated for some time, the free play between brake pads and brake discs increases because of normal brake pad wear. The parking brake control unit performs an automatic correction about every 621 miles (1,000 km). On A8 models, the brake pad thickness is also calculated.
A461525 2022584-2017-11-17. Service bulletin. STEERING: STEERING WHEEL/HANDLE BAR; SERVICE BRAKES, HYDRAULIC. Supersedes Technical Service Bulletin Group 46 number 14-86 dated July 14, 2014.

This TSB is only intended for diagnostic purposes and does not serve as a guideline for determining warrantable conditions. Customer may report that the steering wheel vibrates or pulsates when the brakes are applied. driving style, environmental conditions, and service history of the vehicle. Additionally, as brake pads and discs wear, their dampening ability is reduced. Disc thickness variation (DTV) is a common condition that contributes to brake pulsation. DTV occurs when the two braking surfaces of the brake disc are no longer parallel to each other. This condition cannot be accurately measured with normal workshop tools.
A461523 2034181-2017-11-17. Service bulletin. SERVICE BRAKES. Supersedes Technical Service Bulletin Group 46 number 15-02 dated February 9, 2015.

DO NOT use this TSB if there is another brake noise TSB applicable to the VIN. For additional information, refer to the Audi Brake systems brochure. Brake noise can be attributed to many causes. Brake discs or brake pads are close to or below their wear limit. New brake pads and/or discs have not been properly imbedded after installation. Aftermarket pads or discs are installed. There is debris (such as small stones, grit, road salt, or sand) between brake disc and brake pad. Discs are covered with rust. Rust can form when the vehicle has not been driven for a long period of time. Discs are grooved. There is chemical contamination on the braking surface of the brake disc due to wheel or tire cleaner being sprayed directly onto the brake disc. There are ?pad marks? on the brake disc as a result of brake pad material transferring to the discs. Pad marks can occur when a vehicle has been parked for long periods of time in a wet or snowy environment.
