2021-2022 Audi Starter-Alternator Service Action 27BQ

Audi has released an important dealer communication regarding Service Action 27BQ, which addresses a potential issue with the starter-alternator in various 2021-2022 models.

Why This Matters: Defective Starter-Alternator and Emissions

A defective starter-alternator can lead to several noticeable issues for vehicle owners. The primary concern is its impact on the vehicle's start/stop functionality. If the starter-alternator is not working correctly, the engine's automatic start/stop feature may be inhibited, meaning the engine will not shut off when the vehicle comes to a stop.

While the vehicle remains safe to drive, this condition can lead to an increase in CO2 and other emissions when the vehicle is idling. Audi has confirmed that even with this issue, emissions still remain within certification standards. However, replacing the defective component ensures the vehicle operates as intended, contributing to environmental efficiency.
