2021-2022 Audi e-tron Battery Thermal Overload Campaign Tools

Audi has issued an Advanced Tool Requirement Notice, identified by NHTSA ID 10250231, to its dealerships. This document, dated February 2, 2024, serves to prepare service centers for an upcoming campaign targeting a critical issue in certain 2021-2022 Audi e-tron vehicles. The campaign is anticipated to launch in February 2024.

The notice specifically outlines the extensive list of specialized tools and equipment that dealerships must have on hand and in good working order. This preparation is crucial for successfully addressing a potential battery thermal overload condition in affected vehicles.

Important Warnings for Owners

Audi emphasizes that the repair information contained in this document is exclusively for skilled technicians with the proper tools, equipment, and training. These procedures are not intended for "do-it-yourselfers." Owners should not assume this document applies to their specific vehicle or that their vehicle has the described condition. To determine applicability, always contact an authorized Audi dealer.

What This Notice Means for the Upcoming Campaign

This Advanced Tool Requirement Notice is a preparatory step for Audi dealerships. It ensures that when the upcoming campaign officially launches, technicians will have all the necessary equipment to perform the required service. The campaign itself aims to resolve a potentially critical self-discharge condition within high-voltage battery modules. In some instances, this condition may lead to thermal overload, which could result in smoke or even fire. Early indications of this issue in affected high-voltage batteries may include a loss of range or performance.

Required Tools and Parts

To address the potential Audi e-tron battery thermal overload, Audi dealerships are required to procure a comprehensive set of specialized tools and parts. These items are essential for safely and effectively performing the service action associated with the upcoming campaign. Dealers can obtain ordering information through the Audi Service Tools & Equipment Program or audi.snapon.com.
