Service bulletins for the 2012 Audi A6

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.

011463203363022022-10-31. Service bulletin. ELECTRICAL SYSTEM. Because there are a number of different misfire faults (unrelated to ignition coil operation) that could cause the MIL to illuminate, proper Guided Fault Finding (GFF) misfire diagnosis must be followed before any ignition coils are replaced.
011451203058082022-10-31. Service bulletin. ELECTRICAL SYSTEM:IGNITION:ANTI-THEFT:IMMOBILIZER/PROXIMITY:KEY/SENDER. The remote key being used is transmitting incomplete immobilizer information to the vehicle, resulting in the condition.
011397203058062022-10-31. Service bulletin. ELECTRICAL SYSTEM:IGNITION:ANTI-THEFT:IMMOBILIZER/PROXIMITY:KEY/SENDER. The customer complains that the vehicle sporadically cannot be started. The remote key being used is transmitting incomplete immobilizer information to the vehicle; resulting in the condition.
011394203058052022-10-31. Service bulletin. ELECTRICAL SYSTEM:IGNITION:ANTI-THEFT:IMMOBILIZER/PROXIMITY:KEY/SENDER. The remote key being used is transmitting incomplete immobilizer information to the vehicle; resulting in the condition.
011390203376712022-10-31. Service bulletin. ELECTRICAL SYSTEM. 01 MIL on (DTC P1196/P1197/P0135, heater circuit fault lambda sensor) - Repair Authorization
011386203363012022-10-31. Service bulletin. ELECTRICAL SYSTEM:IGNITION; ELECTRICAL SYSTEM. Because there are a number of different misfire faults (unrelated to ignition coil operation) that could cause the MIL to illuminate, proper Guided Fault Finding (GFF) misfire diagnosis must be followed before any ignition coils are replaced.
011366203145832022-10-31. Service bulletin. ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CRANKCASE (PCV). Under extreme driving conditions, such as a driving profile of mainly short distance (stop and go) driving high crankcase pressure can lead to the above described DTC codes.
011307202934062022-10-31. Service bulletin. ELECTRICAL SYSTEM. The faults listed above are caused by an incorrect software setting and can occur under certain driving conditions. In some scenarios, such as extended idling or heavy stop-and-go traffic, a slight misinterpretation of the data can occur and the MIL may be activated.
011259202773262022-10-31. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; ELECTRICAL SYSTEM. Software update needed.
011258203145812022-10-31. Service bulletin. ELECTRICAL SYSTEM. Under extreme driving conditions, such as a driving profile of mainly short distance (stop and go) driving high crankcase pressure can lead to the above described DTC codes. By changing the crankcase pressure valve to a lower operating pressure this condition can be improved and eliminate the mentioned possible DTC codes. Along with the crankcase pressure being lowered, a new ECM software level is required to compensate for new crankcase pressure.
001470203920612022-10-31. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT. High quality media files (video and sound) are now integrated into technical service bulletins on a case-by-case basis. Media files can now be viewed on any smartphone or tablet.
