2021-2026 Audi HV Module Documentation TSB 2067544/6

Audi Technical Service Bulletin (TSB) 2067544/6, issued on January 13, 2026, provides crucial instructions for technicians regarding the replacement of high-voltage (HV) cell modules in Audi's electrified vehicle lineup. This bulletin emphasizes the importance of proper documentation to ensure traceability, facilitate analysis, and secure warranty claims for these specialized components. The core focus of this TSB is the meticulous process of recording specific information whenever high-voltage cell modules are removed or replaced.

This TSB applies to all 2021-2026 Audi BEV and PHEV vehicles. The proper execution of the Audi high-voltage module documentation procedure is vital for both the manufacturer and the vehicle owner, impacting future analysis and warranty eligibility.

Important Warnings and Requirements

This TSB contains several critical warnings and non-negotiable requirements that highlight the strict protocols surrounding high-voltage battery components:

• Classification Before Removal: "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."
• Disposal Restriction: "Please do not dispose of removed high-voltage modules without prior consultation." Audi AG is highly interested in analyzing all replaced modules.
• Warranty Claim Dependency: "The warranty claim will not be paid until the information label is uploaded to Doc-IT for every high-voltage cell module removed."
• TSB Nature: "This TSB is informational only and does not apply to any Audi Warranty."

Purpose of the TSB

The primary purpose of TSB 2067544/6 is to ensure comprehensive documentation of high-voltage cell modules that are replaced during repair work on the high-voltage system. This meticulous record-keeping is essential for several reasons, including enhancing traceability for future analysis requests, facilitating proper recycling of removed modules, and ensuring the accurate processing of warranty claims. Audi AG has a strong interest in examining replaced high-voltage modules to improve product quality and understand failure modes.

Service Procedure for High-Voltage Module Replacement

When high-voltage cell modules of the high-voltage battery are replaced as part of repair work on an electric Audi, specific documentation steps must be followed. This procedure is mandatory unless a different approach has been explicitly agreed upon, for instance, in a field campaign description or via Technical Assistance Center (TAC) instructions.

Step 1: Documenting the Vehicle Identification Number (VIN)

For every high-voltage cell module that is removed from a vehicle, technicians must document the chassis number (VIN) of the vehicle. This VIN must be written directly onto the removed high-voltage cell module using a waterproof pen. This ensures a direct link between the removed component and its original vehicle.

Step 2: Documenting the Module Serial Number and Uploading Information

After documenting the VIN, the next critical step is to record the serial number of every removed high-voltage cell module. This is achieved by taking a clear picture of the information label found on the module itself. This picture, containing the serial number, must then be uploaded to Doc-IT, which is located within Audi Warranty Online. Examples of these labels are shown in the TSB, including one from an Audi e-tron Quattro (part number 4KE.915.591.H) and another from an Audi Q5 PHEV (part number 80A.915.100.E).

Warranty Implications

Adherence to the documentation procedure outlined in TSB 2067544/6 is directly tied to warranty claim processing. Audi explicitly states that any warranty claim related to the replacement of high-voltage cell modules will not be paid unless the information label for every removed module has been successfully uploaded to Doc-IT. While the TSB itself is informational and does not directly apply to the Audi Warranty policy, following its guidelines is crucial for ensuring that repair costs are covered under warranty.

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

Technical Background

Audi AG's strong interest in the analysis and recycling of removed high-voltage modules necessitates this documentation process. The goal is to ensure better traceability of these components throughout their lifecycle. By documenting the data described in this TSB, Audi can efficiently process and organize the transport of these modules for analysis. This process helps in understanding potential issues, improving future designs, and ensuring environmentally responsible recycling.
