2021-2022 Audi e-tron Battery Control Unit Software Update

What is Audi Dealer Communication UPDATE 93N6?

Audi has released a dealer communication, identified as UPDATE 93N6, concerning a revision to the Software Version Management (SVM) update instructions for the Battery Modules Control Unit Software. This notice, dated September 25, 2024, is directed at all Audi dealer personnel. It highlights an update to the procedures used for servicing the battery control unit software in affected vehicles, including the 2021-2022 Audi e-tron and e-tron Sportback.

The Battery Modules Control Unit Software is a critical component responsible for managing various aspects of the high-voltage battery system, such as charging, discharging, thermal management, and overall state of charge. Ensuring this software is up-to-date and correctly configured is vital for the vehicle's performance, range, and safety. This communication is primarily an internal procedural update for dealerships, ensuring technicians have the most current and accurate instructions when performing software updates related to the Audi e-tron battery software.

Purpose of the Revision

The core purpose of this revision is to ensure consistency and accuracy across all Audi dealerships. The SVM update instructions, which guide technicians through the software update process for the Battery Modules Control Unit, have been revised. This means that previous versions of these instructions are now outdated and should no longer be used.

Audi emphasizes that all dealership staff with campaign-related responsibilities must thoroughly review the updated bulletin. This ensures they are fully aware of the latest procedures published in ELSA and Service References in Elsa2Go. ELSA (Electronic Service Information System) and Elsa2Go are Audi's comprehensive technical information systems, providing essential repair manuals, wiring diagrams, and service bulletins to technicians.

Important Warnings for Dealerships

Audi explicitly instructs dealerships to discard any previously printed paper copies of the SVM update instructions. These older versions must be replaced with the most current version available. This directive prevents the use of outdated procedures, which could lead to incorrect service, potential vehicle malfunctions, or delays in campaign completion.

This measure is critical for maintaining high service quality and ensuring that any work performed on the Audi e-tron battery software is done according to the latest manufacturer guidelines. The communication, UPDATE 93N6, underscores Audi's commitment to providing accurate information to its service network and preventing errors that could arise from using obsolete documentation.

What Owners Should Know

While this is an internal dealer communication, it indirectly benefits owners of 2021-2022 Audi e-tron and e-tron Sportback models. It ensures that when your vehicle requires a software update for the Battery Modules Control Unit, the service will be performed using the most current and correct procedures. This helps guarantee the proper functioning, reliability, and longevity of your Audi e-tron battery software and overall electric vehicle system.

Owners are not directly required to take any action based on this specific communication. However, if your vehicle is subject to a service campaign that involves the Battery Modules Control Unit Software, you can be assured that your dealership will be working with the most up-to-date instructions. For any questions regarding your vehicle's service needs or open campaigns, it is always recommended to contact your authorized Audi dealership.
