Service bulletins for the 2012 Audi A8

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

A431314 2018765-	2017-11-17. Service bulletin. SUSPENSION:REAR:SPRINGS:AIR SUSPENSION SYSTEM; SUSPENSION:FRONT:SPRINGS:AIR SUSPENSION SYSTEM. Supersedes Technical Service Bulletin Group 43 number 12-11 dated October 29, 2012. The self-leveling system can no longer be adjusted with the MMI. The compressor for the self-leveling system continues to run after the engine has been switched off and the vehicle has been locked. DTCs may be stored in the level control system module, J197 (address word 34). Because of poor performance or failure of the air suspension compressor, the vehicle ride height cannot be adjusted. As a safeguard, the control module will lower the vehicle to the lowest position and illuminate the warning light. Drivability is not affected.
A401329 2033344-	2017-11-17. Service bulletin. SUSPENSION:FRONT:SPRINGS:AIR SUSPENSION SYSTEM. Customer may hear squeaking or beeping noises from front of vehicle when driving on uneven roads after a stationary period. This condition occurs on vehicles with air suspension (PR-1BK) if the damper was very warm when the engine was switched off. The noise disappears as the damper warms up, after compressing once or twice. Bubbles are created in the oil because of temperature fluctuations, particles, and high oil flow speed. The bubbles gather around the damping adjustment valve when the engine is switched off. When the vehicle is started again, the cold oil prevents the bubbles from being dispersed quickly, which reduces the hydraulic damping. The reduced hydraulic damping causes the armature in the damper to vibrate, which creates squeaking noises. As soon as the bubbles have been dispersed, the hydraulic damping works fully and the noise disappears.
