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.

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.
