The focus of this revision is to provide additional clarity and detail to technicians.

Understanding Service Action 27K2

Service Action 27K2 is an ongoing campaign initiated by Audi to update the software within the 12V Battery Control Module. This module plays a vital role in managing the vehicle's conventional 12-volt electrical system, which powers essential components like lighting, infotainment, and various control units. Ensuring this software is up-to-date is critical for the optimal performance and reliability of these systems in your 2022 Audi e-tron GT.

Key Revision Details: Required Voltage Information

The most significant aspect of this February 22, 2023 revision is the inclusion of specific information regarding the "required voltage" during the 12V Battery Control Module software update procedure.

Insufficient voltage during such an operation can lead to incomplete software installation, module corruption, or even permanent damage to the control unit, necessitating costly replacement. Audi's addition of this detail in the revised 27K2 Service Action work instructions underscores its importance for a successful and trouble-free update.

This minimizes the risk of complications during the update process and helps ensure the longevity and proper functioning of the battery control system. While this specific document is a dealer communication, its ultimate goal is to enhance the quality of service provided to customers and maintain the performance of the 2022 Audi e-tron GT 12V battery software.

What Owners Should Know

It's important to understand that this document is a revision notice for internal dealership use, not a direct recall or owner notification. Therefore, owners of affected vehicles, such as the 2022 Audi e-tron GT, will not typically receive a letter specifically about this revision.
