2021-2025 Audi e-tron HV Module Documentation TSB

Audi Technical Service Bulletin (TSB) 2067544/2, issued on July 19, 2023, provides crucial information regarding the documentation of high-voltage (HV) cell modules when they are replaced in certain Audi e-quattro models. This bulletin supersedes the previous TSB Group 93 number 22-78 dated August 2, 2022, with updated information including additional model years.

The primary focus of this TSB is to ensure that technicians properly record specific information when performing repairs involving the high-voltage system. This process is vital for the traceability and proper handling of removed HV modules, impacting warranty claims and future analysis.

Important Warnings

Technicians must adhere to specific safety and procedural guidelines when handling high-voltage components. The TSB explicitly states:

"A high-voltage battery or high-voltage module must always be classified before removing the battery/module. Without classification, a high-voltage battery or high-voltage module cannot be transported or recycled."

This warning underscores the critical importance of proper handling and classification to prevent safety hazards and ensure compliance with environmental regulations.

Why This Documentation Matters

The technical background for this TSB highlights the necessity of documenting replaced high-voltage cell modules. This documentation ensures better traceability in the event of an analysis request or for the recycling of removed high-voltage modules.

Proper record-keeping is essential for understanding the lifecycle of these critical components and for future diagnostic or recycling efforts. This process is a key part of maintaining the integrity of the high-voltage system and supporting ongoing vehicle safety and environmental standards.

Documentation Procedure Summary

When a high-voltage cell module of the high-voltage battery is replaced, technicians must follow a two-step documentation process to ensure compliance and proper record-keeping. This procedure is critical for any repair work on the high-voltage system, especially for the 2021-2025 Audi e-tron and related models.

Step 1: VIN Documentation on Removed Module

Upon removal of a high-voltage cell module, the chassis number (VIN) of the vehicle must be documented directly onto every removed high-voltage module. This should be done using a waterproof pen to ensure the VIN remains legible.

Step 2: Serial Number Documentation and Upload

Technicians are required to document the serial number of every removed high-voltage cell module. This is achieved by uploading a picture of the information label from the removed module to Doc-IT, located within Audi Warranty Online. The TSB emphasizes that warranty claims will not be paid until this information label is successfully uploaded for every high-voltage cell module removed.

Figures 1 and 2 in the TSB provide examples of cell module identification labels, showing where the serial numbers can be found on modules like the 4KE.915.591.H (e-tron Quattro) and 80A.915.100.E (Q5 PHEV). This ensures the correct identification and recording of the specific module being replaced.

Affected Components

This documentation requirement specifically applies to high-voltage cell modules, which are integral parts of the high-voltage battery system in affected Audi e-quattro vehicles. The accurate identification and recording of these components, particularly their serial numbers, is paramount.

Warranty Information

It is important for owners and technicians to note that this Technical Service Bulletin is informational only. It does not directly apply to any Audi Warranty claims related to the repair itself. However, as stated, proper documentation is a prerequisite for warranty claim payment for the repair work involving the HV modules.

Additional Information for Technicians

All part and service references provided in TSB 2067544 are subject to change and/or removal. Technicians should always consult their Parts Department and/or ETKA for the most current information and parts bulletins. Additionally, the Repair Manual should be checked for any fasteners, bolts, nuts, and screws that require replacement during the repair process.

For further details on obtaining the necessary photos for HV battery documentation, technicians should refer to Warranty Communication AWA-22-10: "HV Battery Photo Documentation."
