Service bulletins for the 2012 Audi A4

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.

37 13 79 20293052022-05-02. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Further TCM software calibration to improve shift concerns.
37 13 17 20290272022-05-02. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). The DTCs are stored due to an issue with the transmission control module software. Specific DFCCs are stored as a result of the following situations: ? DTC P060A00 with DFCC 8692 can be logged when a driving mode (Drive or Reverse) is selected within one second of selecting Neutral, while the vehicle rolls at a speed less than 2 mph (such as when the vehicle is being maneuvered in or out of a parking spot). ? DTC P060A00 with DFCC 8694 can be logged when the gear is quickly changed from Park to Neutral, due to a low diagnosis threshold. ? DTC P060A00 with DFCC 12480 can be logged when the gear is changed using the Tiptronic function, due to a low diagnosis threshold.
37 13 05 20305822022-05-02. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). The entry is caused by an overly sensitive diagnosis in the transmission control module.

37 13 01 20289852022-05-02. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). The fault occurs with ATF temperature below 60o C. Check for this temperature range in the extended environmental conditions of the diagnosis protocol. This TSB only applies if the ATF level is correct and there are no leaks.
37 13 00 20328122022-05-02. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ELECTRICAL SYSTEM:SOFTWARE. Further transmission control module (TCM), J217, software calibration needed to improve shift concerns. Further engine control module (ECM), J623, software calibration needed to improve hesitation.
37 12 74 20293052022-05-02. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ELECTRICAL SYSTEM:SOFTWARE. Harsh downshifts when braking or harsh 1-2 upshift under acceleration. Customer may report harsh downshifts while braking or harsh 1-2 upshift under acceleration. Further TCM software calibration to improve shift concerns.
37 12 72 20289852022-05-02. Service bulletin. ELECTRICAL SYSTEM:ADAS:HUD:SOFTWARE; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Customer may report transmission warning lamp illuminated in instrument cluster. Fault code P074100 Torque Converter Clutch Circuit Performance or Stuck Off is stored in TCM.
37 12 71 20293052022-05-02. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM).
