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.

| A571382 2017082- | 2017-11-17. Service bulletin. LATCHES/LOCKS/LINKAGES; EQUIPMENT:ELECTRICAL. Supersedes Technical Service Bulletin Group 57 number 11-55 dated August 22, 2011. Central locking via remote control does not work either sporadically or permanently. The locks can still be operated manually. Missing synchronization between the remote control key and vehicle because the battery has been disconnected or the battery of the remote control has been replaced. If other senders operate in the same frequency range (mobile phones, TV stations, wireless headphones, baby monitors, other vehicle remote controls, etc.), the remote control key may have been temporarily switched off because a clear identification of the remote control key is not possible. This is necessary to prevent an unintentional unlocking of the vehicle by other unrelated senders. |

| 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. |
| A481340 2033377- | 2017-11-17. Service bulletin. STEERING:ELECTRIC POWER ASSIST SYSTEM; STEERING:COLUMN; ELECTRICAL SYSTEM:SOFTWARE. Customer states the vertical adjustment of the steering column does not work or works intermittently. Concern may or may not be duplicated. Software issues causing sporadic failure of the power steering column vertical adjustment. |

| A571385 2017082- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM; LATCHES/LOCKS/LINKAGES:DOORS:LATCH. Supersedes Technical Service Bulletin Group 57 number 13-82 dated February 5, 2013. Central locking via remote control does not work either sporadically or permanently. The locks can still be operated manually. Missing synchronization between the remote control key and vehicle because the battery has been disconnected or the battery of the remote control has been replaced. If other senders operate in the same frequency range (mobile phones, TV stations, wireless headphones, baby monitors, other vehicle remote controls, etc.), the remote control key may have been temporarily switched off because a clear identification of the remote control key is not possible. This is necessary to prevent an unintentional unlocking of the vehicle by other unrelated senders. |
| A571386 2027368- | 2017-11-17. Service bulletin. STRUCTURE:BODY:DOOR; LATCHES/LOCKS/LINKAGES:DOORS:LATCH. Supersedes Technical Service Bulletin Group 57 number 12-73 dated September 24, 2012. The exterior door handle touch sensors (Advanced key) are inoperative on one or several doors. The key blade can be used mechanically (driver door or trunk) or remote electrically (key remote buttons) to unlock and lock the vehicle. |
| A571387 2029151- | 2017-11-17. Service bulletin. LATCHES/LOCKS/LINKAGES:DOORS:LATCH; STRUCTURE:BODY:DOOR. Supersedes Technical Service Bulletin Group 57 number 12-80 dated November 9, 2012. The door cannot be opened from outside with the outer door handle, but it can be opened with the inner handle. The complaint is often described as follows: The customer locks the vehicle and checks by pulling the door handle whether the vehicle is locked. When opening the vehicle again, the door cannot be opened. It feels as if the handle is slack. |
| A851314 2033428- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. The instrument panel vents cannot be adjusted. The knob may be broken. The force required to adjust the vent is greater than the attachment strength of the knob. As a result, the knob may break. |
| A911378 2033355- | 2017-11-17. Service bulletin. FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL. Adaptive Cruise Control (ACC) does not work. The message "ACC and braking guard: unavailable at this time. No sensor vision" appears in the instrument cluster. DTC is logged in the distance regulation control module, J428 (address word 13). |
| A911380 2032706- | 2017-11-17. Service bulletin. EQUIPMENT:ELECTRICAL:RADIO/TAPE DECK/CD ETC.. Supersedes Technical Service Bulletin Group 91 number 13-73 dated January 25, 2013. Customer complains of a "popping" noise from the radio followed by 10-15 seconds of no audio. The concern can happen in any audio source. Vehicle is equipped with MMI 3G or MMI 3G+ infotainment systems. Vehicle is not equipped with Bose or Bang & Olufsen sound systems. An ignition cycle is not required for audio to resume.The problem originates in the HD radio code, which can create a "resetting" within the radio unit. Because the tuner is always active in the background, the problem can occur regardless of the audio source or if the HD radio is on or off. It can also occur at any point that the MMI is on, but not necessarily active. For example, the customer opens a door and the MMI starts up. Even though the system is not ?on? because the ignition is not active, the tuner is running and can create the effect. |
| Update Bulletin- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM. On Audi A8 vehicles manufactured within a specific period, the system diagnosis may detect a sporadic implausible condition of the selector lever sensors when the ignition is switched on.
