2021-2026 Audi HV Module Documentation TSB 2067544/5

Audi has issued Technical Service Bulletin (TSB) 93 25 48 2067544/5 to provide critical instructions regarding the documentation of high-voltage (HV) cell modules when they are replaced in Hybrid and e-tron vehicles. This TSB, which supersedes Group 93 number 24-35 dated November 22, 2024, is essential for ensuring proper traceability and warranty processing related to HV battery repairs. The bulletin applies to various Audi models from 2021 to 2026.

This TSB specifically addresses the process for Audi HV module documentation during high-voltage battery service. It ensures that every replaced high-voltage cell module is properly identified and recorded.

What This TSB Addresses

This TSB highlights the importance of documenting high-voltage cell modules that have been replaced as part of repair work on the high-voltage system. The primary goal is to ensure better traceability for analysis requests or recycling of removed HV modules. Audi AG has a strong interest in analyzing these replaced modules.

Important Warnings for Owners and Technicians

Audi emphasizes several critical points regarding high-voltage components:

• "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."
• Technicians are reminded to "Remember to document high-voltage cell modules which have been replaced."
• It is crucial to "Contact importer before disposing of high-voltage modules." Audi explicitly states, "Please do not dispose of removed high-voltage modules without prior consultation." This is to allow Audi AG to analyze the modules and organize transport for processing.
• A significant warning for warranty claims: "The warranty claim will not be paid until the information label is uploaded to Doc-IT for every high-voltage cell module removed."

Required Documentation Steps

When a high-voltage module is replaced during a high-voltage battery repair, specific documentation steps must be followed:

1. Step 1: VIN Documentation Using a waterproof pen, technicians must document the vehicle's chassis number (VIN) on every high-voltage cell module that has been removed from the vehicle.

2. Step 2: Serial Number Documentation The serial number of every removed high-voltage cell module must be documented by uploading a picture of its information label to the Doc-IT system within Audi Warranty Online. The serial numbers are found directly on the module's label. Examples of these labels include part numbers like 4KE.915.591.H (from an Audi e-tron Quattro) and 80A.915.100.E (from an Audi Q5 PHEV).

Affected Components

This TSB specifically concerns high-voltage cell modules within the high-voltage battery system. While not a fault code, the proper Audi HV module documentation is crucial for the integrity of the repair process.

Warranty Information

This Technical Service Bulletin (TSB 2067544) is informational only and does not apply to any Audi Warranty directly. However, adherence to its documentation requirements is mandatory for warranty claims related to high-voltage battery repairs.

Additional Resources

For further information on obtaining the necessary photos for documentation, technicians should refer to Warranty Communication AWA-22-10: HV Battery Photo Documentation. All part and service references in this TSB, including the main TSB number 2067544, are subject to change. Technicians should always consult their Parts Department, ETKA, and the Repair Manual for the latest information and specific instructions regarding fasteners, bolts, nuts, and screws.

Owner Action

If your 2021-2026 Audi Hybrid/e-tron vehicle requires high-voltage battery service involving the replacement of cell modules, ensure your service center is aware of and follows TSB 93 25 48 2067544/5 for proper Audi HV module documentation. This ensures that any future warranty claims related to the high-voltage system are processed correctly and that removed modules are handled according to Audi's guidelines for analysis and recycling.
