Official 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.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
