2021-2024 Audi Starter-Alternator Emissions Service Action 27BQ

Why This Matters

Audi has initiated Emissions Service Action 27BQ to proactively address a component that could impact vehicle emissions. This revision, dated December 17, 2024, specifically highlights updates to the parts information. While the issue does not mean vehicles are exceeding certification standards, it ensures optimal performance of the start/stop system and adherence to environmental regulations. This service action demonstrates Audi's commitment to maintaining the efficiency and compliance of its vehicles.

What's Being Addressed

This service action, identified as 27BQ, focuses on the starter-alternator unit in affected Audi vehicles. The starter-alternator is a key component in modern vehicles, especially those equipped with start/stop technology. It is responsible for both starting the engine and generating electrical power for the vehicle's systems.

If the starter-alternator is not functioning optimally, it could inhibit the vehicle's start/stop functionality. This means the engine might not automatically shut off when the vehicle is stopped (e.g., at a traffic light) and restart seamlessly when the brake pedal is released. Such an inhibition could lead to increased CO2 and other emissions during periods when the vehicle would normally be idle.

Manufacturer's Remedy

Under Emissions Service Action 27BQ, authorized Audi dealerships will replace the starter-alternator in all affected vehicles. This repair will be performed at no cost to the owner. The service action aims to restore full functionality of the start/stop system and ensure that the vehicle operates as designed, maintaining its emissions profile. The updated parts information ensures that the correct components are used for this critical repair.

Owners of a 2021-2024 Audi Q8 starter-alternator issue, or any other affected model, should contact their local Audi dealer to schedule this service. The manufacturer communication indicates that updates have been made to parts information, reflecting the addition of more vehicles to the campaign.

Important Notes for Owners

Audi is committed to ensuring that its dealerships are fully prepared to handle this service action. Dealer personnel have been instructed to thoroughly review the revised circulars published in ELSA and Service References in Elsa2Go, which contain updated campaign-related responsibilities and parts information. This ensures that technicians have the most current procedures and parts available for the repair.

Furthermore, Audi has instructed dealers to discard any previously printed paper copies of the circular and replace them with the most current version. This measure is crucial to prevent the use of outdated information or incorrect parts during the service procedure for your 2021-2024 Audi Q8 starter-alternator or other affected models.

While this is not a recall, it is an important service action to maintain your vehicle's performance and environmental compliance. If you own a 2021-2024 Audi Q8 starter-alternator issue or any other model covered by this action, it is recommended to have the service performed promptly.
