Service campaign Circ 27BQ_REV4

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.

NHTSA's summary

Under this service action, Audi dealers will replace the starter-alternator in affected vehicles at no cost to owners. A defective starter-alternator may inhibit start/stop functionality which could increase CO2 and other emissions while the vehicle is stopped. Emissions still remain within certification standards. Updated affected vehicle chart & owner notification letters to reflect the addition of 2021 model year. Parts and claiming instructions updated.

The document

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
