Service bulletins for the 2013 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.

Customer may report transmission warning light is illuminated. In some cases, the vehicle will not move after being started and placed into gear. After key cycle, the vehicle drives without restriction. The DTCs are stored due to an issue with the transmission control module software.
37 14 24 20371272022-05-02. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ELECTRICAL SYSTEM:SOFTWARE; POWER TRAIN; ELECTRICAL SYSTEM. A jerky accelerator response is felt when the vehicle is pulled away from a stop in reverse. Incorrect calibration of clutch program. New software in the transmission control module (TCM), J217 (address word 02) addressed the condition.
37 14 22 20289852022-05-02. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; UNKNOWN OR OTHER; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). The fault occurs with ATF temperature below 60° 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 99 20290272022-05-02. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ELECTRICAL SYSTEM; POWER TRAIN; ELECTRICAL SYSTEM:SOFTWARE. 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.
