2021-2026 Audi EV High-Voltage Module Documentation TSB

Audi has released Technical Service Bulletin (TSB) 93 24 13 2067544/3, updated on September 18, 2024, to clarify the documentation requirements when replacing high-voltage (HV) cell modules in various electric and plug-in hybrid vehicles. This TSB is crucial for ensuring proper traceability and processing of warranty claims related to high-voltage battery repairs for the affected 2021-2026 Audi EV high-voltage module systems.

This bulletin supersedes an earlier version, Group 93 number 23-16, dated July 19, 2023, with updates primarily focused on visibility and the addition of more model years to the scope. The core message emphasizes the importance of meticulously documenting every replaced high-voltage cell module.

Why Proper Documentation is Crucial

The primary purpose of this TSB is to establish a clear record for high-voltage modules that are removed from vehicles. This documentation is essential for several reasons, including potential analysis requests and the proper recycling of these specialized components. By documenting specific data, Audi aims to maintain better traceability throughout the lifecycle of these critical high-voltage parts.

Important Safety Information

Audi highlights a critical safety warning regarding the handling of high-voltage components. Any high-voltage battery or high-voltage module must be properly classified before removal. Failure to classify these components correctly means they cannot be safely transported or recycled. This underscores the specialized nature of working with an Audi EV high-voltage module and the strict protocols required.

Required Documentation Steps for HV Module Replacement

When a high-voltage module is replaced as part of a high-voltage battery repair, specific documentation steps must be followed. These steps are mandatory to ensure that warranty claims are processed correctly and to maintain the necessary traceability for each Audi EV high-voltage module:

1. Document Vehicle Identification Number (VIN): For every high-voltage cell module removed from a vehicle, the chassis number (VIN) of that vehicle must be clearly documented on the module itself. Technicians are instructed to use a waterproof pen for this purpose.
2. Document Serial Number and Upload Information Label: The serial number of each removed high-voltage cell module must be documented. This is achieved by uploading a picture of the module's information label to the Doc-IT system, accessible via Audi Warranty Online. It is explicitly stated that warranty claims will not be paid unless the information label for every removed high-voltage cell module has been successfully uploaded to Doc-IT.

Identifying High-Voltage Module Labels

The serial numbers and other critical information for high-voltage modules are found on labels directly affixed to the relevant module. The TSB provides examples of these labels, showing typical layouts for an Audi e-tron Quattro and an Audi Q5 PHEV. These labels contain identifiers such as
