2021-2026 Audi HV Module Replacement Documentation TSB

Audi has issued Technical Service Bulletin (TSB) 2067544/6, effective January 13, 2026, to address the critical procedure for documenting high-voltage (HV) cell modules when they are replaced in certain electric and plug-in hybrid vehicles. This TSB applies to all 2021-2026 Audi BEV (Battery Electric Vehicle) and PHEV (Plug-in Hybrid Electric Vehicle) models. The primary purpose of this Audi HV module documentation requirement is to ensure proper traceability for analysis, recycling, and warranty claims related to high-voltage battery components.

Why This Documentation Matters

Audi AG has a strong interest in analyzing and potentially recycling high-voltage modules that have been removed from vehicles. Accurate documentation of these components is crucial for several reasons. It ensures better traceability for any future analysis requests or recycling processes.

Without proper documentation, it becomes difficult to track the history and specifications of individual modules. This Audi HV module documentation process helps maintain a comprehensive record of replaced parts, which is vital for quality control and environmental responsibility.

Understanding the Documentation Process

When a high-voltage cell module or an entire high-voltage battery is replaced during repair work, specific documentation steps must be followed. These steps are mandatory for warranty claims to be processed successfully.

First, technicians must use a waterproof pen to clearly write the vehicle's chassis number (VIN) on every high-voltage cell module that is removed. This ensures that each removed module is directly linked to its original vehicle.

Second, the serial number of each removed high-voltage cell module must be documented. This is done by uploading a clear picture of the information label from the module to the Doc-IT system, which is part of Audi Warranty Online. The information labels, such as those found on the LI-Ion Battery E61VLGP (part number 4KE.915.591.H) from an Audi e-tron Quattro or the 80A.915.100.E from an Audi Q5 PHEV, contain the necessary serial numbers and other identifying details.

Required Tools and Information

For technicians, the key requirements for this procedure include a waterproof pen for marking VINs and access to the Doc-IT system within Audi Warranty Online for uploading photos. The information labels on the high-voltage modules themselves are the source of the critical serial number data.

Additionally, technicians are advised to refer to Warranty Communication AWA-22-10, titled "HV Battery Photo Documentation," for further guidance on obtaining the necessary photographs. This ensures that the images captured meet Audi's specific requirements for clarity and content.

Important Safety and Warranty Information

Before any high-voltage battery or module is removed, it must be properly classified. Failure to classify these components correctly means they cannot be transported or recycled safely. This is a critical safety measure to prevent hazards associated with high-voltage systems.

It is important to note that this TSB is informational and does not directly apply to any Audi warranty in terms of coverage. However, adhering to the documentation procedure is essential for any warranty claim involving high-voltage module replacement to be paid. Audi also requests that importers be contacted before disposing of any removed high-voltage modules, as they may wish to analyze them.

Owner Action

As an owner of an affected 2021-2026 Audi BEV or PHEV, there is no direct action required from you regarding this TSB. This bulletin primarily outlines a procedure for Audi service technicians. However, if your vehicle requires high-voltage battery or module replacement, it's beneficial to be aware of this Audi HV module documentation process. Ensuring your service center follows these steps correctly will help facilitate any potential warranty claims and contribute to the proper handling of high-voltage components.
