2021-2022 Audi e-tron High-Voltage Battery Tool Notice

Audi has released an "Upcoming Campaign Advanced Tool Requirement Notice" to its dealerships, signaling preparation for a significant service action. This notice, identified by NHTSA ID 10249586, outlines the specialized tools and equipment required to address a potentially critical high-voltage battery issue in certain Audi e-tron models. The purpose is to ensure that dealerships are fully equipped to perform the necessary repairs once the campaign officially launches.

This proactive step by Audi aims to prepare service centers for an upcoming campaign that addresses a serious safety concern. The underlying issue is a potentially critical self-discharge condition within the high-voltage battery modules. This condition could lead to thermal overload, which might result in smoke or even a fire, increasing the Audi e-tron battery fire risk.

Why This Matters

The high-voltage battery self-discharge condition poses a significant safety hazard. If a battery module experiences thermal overload, it increases the risk of a fire. Owners might notice early indications of this problem, such as a loss of range or reduced performance from their vehicle's high-voltage battery. Addressing the Audi e-tron battery fire risk is paramount for vehicle safety.

Campaign Details

This "Upcoming Campaign Advanced Tool Requirement Notice" was issued on January 26, 2024, with an anticipated launch for the campaign in February 2024. The notice serves to inform dealer principals, service managers, parts managers, warranty administrators, and technicians about the specific tools needed to perform the upcoming service procedure. Dealerships are instructed to ensure these tools, or their equivalents, are present and in good working order as soon as possible. For tool ordering information, dealerships can contact the Audi Service Tools & Equipment Program at 1-800-892-9650 or visit audi.snapon.com.
