2021 Audi Service Action 27BQ: Starter-Alternator Emissions

Audi has issued a dealer communication regarding Service Action 27BQ, which focuses on the starter-alternator in certain 2021 models. This action is a revision to an existing service campaign, with a second wave of vehicles now included. The primary goal of this service action is to address potential emissions impacts related to the starter-alternator.

What's Being Addressed

This Service Action addresses a condition where a defective Audi starter-alternator may inhibit the vehicle's start/stop functionality. While emissions are stated to remain within certification standards, the inhibited start/stop function could lead to increased CO2 and other emissions when the vehicle is stopped. The repair aims to restore proper operation and ensure optimal emissions performance.

Manufacturer's Remedy

Under Service Action 27BQ, Audi dealers will replace the defective Audi starter-alternator in the affected vehicles. This repair will be performed at no cost to the owners. Owner notifications for the second wave of vehicles included in this service action are scheduled to take place in August 2024.

Important Information for Owners

Audi is notifying owners in waves, with the second wave of notifications expected in August 2024. While this communication is primarily for dealer personnel, it indicates that dealers are being instructed to thoroughly review the revised circular in their Service References (Elsa2Go and ELSA) to ensure they are prepared to address customer questions and perform the necessary repairs. Owners should await their official notification from Audi regarding this service action.
