Service bulletins for the 2013 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.

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 09 20287152022-05-02. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY; POWER TRAIN:AUTOMATIC TRANSMISSION:INTERNAL:GEARS. After a mechatronics, torque converter, or complete gearbox replacement, the clutches must be adapted to the new component. This requires a gradual move of the clutch linings toward the optimal operating points in the most diverse load conditions. As a result, sporadic driving power disruptions lasting for less than a second or reduced shift comfort are possible over the first 500 miles. This is normal, and these issues will decrease over time. The issues can also occur if the adaptation values of the gearbox were deleted.
