2021-2022 Audi Q8 Starter-Alternator Emissions Service Action

Why This Matters

Audi has initiated Service Action 27BQ to address a potential concern with the starter-alternator in certain 2021-2022 Audi Q8 and other models. The starter-alternator is a key component in modern vehicles, especially those equipped with start/stop technology, as it manages both engine starting and electrical power generation.

A defective starter-alternator can inhibit the proper function of the start/stop system. While this issue does not prevent the vehicle from operating, it can lead to increased CO2 and other emissions when the vehicle is stopped, even if these emissions remain within certified standards. Ensuring all components function as designed helps maintain optimal vehicle performance and environmental compliance.

What's Being Addressed

This service action specifically targets the starter-alternator component in affected vehicles. Audi has identified that a defect in this part could impact the vehicle's start/stop system. This is an emissions-related service action, designated as Service Action 27BQ, aiming to ensure that all vehicles meet their intended emissions performance.

Manufacturer's Remedy

For all vehicles identified under Service Action 27BQ, Audi dealerships will replace the starter-alternator. This repair will be performed at no cost to the owner. The goal is to restore full functionality of the start/stop system and ensure the vehicle's emissions performance aligns with its design specifications.

Owner Notification

Audi will be notifying owners of affected vehicles in waves. Owner notification for Wave 3 is scheduled to take place in October 2024. If your vehicle is among those affected, you will receive official communication from Audi regarding this service action and instructions on how to proceed. It is important to ensure your contact information with Audi is up-to-date.

Important Information for Owners

While this is a dealer communication, there are key takeaways for owners. Audi emphasizes that dealership personnel should thoroughly review the revised circulars published to ELSA and Service References in Elsa2Go. This ensures that all campaign-related responsibilities are understood and that dealers have the most current information regarding the Audi Q8 starter-alternator and related models. Owners should feel confident that their dealership is equipped with the latest guidance to perform this service action correctly.

If you believe your 2021-2022 Audi Q8 or other listed model is affected and you have not received a notification by late October 2024, you can contact your authorized Audi dealer for more information.
