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.

37 14 47 20290272022-05-02. Service bulletin. POWER TRAIN; ELECTRICAL SYSTEM. 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 34 20289852022-05-02. Service bulletin. ELECTRICAL SYSTEM:IGNITION; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE:SOFTWARE; UNKNOWN OR OTHER; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Transmission warning may appear in instrument cluster. After ignition cycle, the warning message is no longer present. 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 14 33 20293052022-05-02. Service bulletin. POWER TRAIN; ELECTRICAL SYSTEM; ENGINE; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE:SOFTWARE. Further transmission control module (TCM), J217 (address word 02), software calibration to improve shift concerns.
37 14 30 20036582022-05-02. Service bulletin. ELECTRONIC STABILITY CONTROL (ESC):CONTROL MODULE:SOFTWARE; POWER TRAIN. This condition may be caused when the brake pedal and the accelerator pedal are depressed simultaneously. Drivers who drive with their left foot resting on the brake pedal are prone to experience this condition. With the introduction of Electronic Power Control (EPC) (no accelerator cable) to fuel injection systems, an engine RPM control feature has been incorporated into the engine electronic control system software. Customer states that the engine returns to idle speed of approximately 1,400 RPM although the accelerator is depressed, and/or the vehicle hesitates (lacks power on take-off).
