2021-2023 Audi e-tron HV Module Documentation TSB

Audi has issued Technical Service Bulletin (TSB) 2067544/1, dated August 2, 2022, to ensure proper documentation of high-voltage (HV) cell modules when they are replaced in various 2021-2023 Audi e-tron and other electrified models. This TSB emphasizes the critical steps technicians must follow for traceability and warranty purposes, specifically concerning the Audi e-tron HV module documentation process.

Why This Documentation Matters

This TSB addresses the need for meticulous record-keeping when replacing high-voltage cell modules within the HV battery system. The primary goal is to enhance traceability for these specialized components.

Improved traceability is essential for several reasons, including facilitating analysis requests for removed modules and ensuring proper recycling procedures. Accurate data collection supports both technical investigations and environmental responsibilities related to HV battery components.

Important Warnings

Technicians must adhere to strict safety and procedural guidelines when handling high-voltage components. A crucial warning highlighted in the TSB 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 means that any HV battery or module must undergo a specific classification process before removal. Failing to do so can prevent the proper and safe transport or recycling of the component, posing significant logistical and environmental challenges.

Documentation Procedure Summary

When a high-voltage cell module is replaced as part of a high-voltage battery repair, specific documentation steps are mandatory. These steps ensure that every replaced module is properly recorded and linked to the vehicle from which it was removed. This meticulous Audi e-tron HV module documentation is vital for future reference and warranty processing.

1. Document Vehicle Identification Number (VIN): Technicians must use a waterproof pen to clearly write the vehicle's chassis number (VIN) on every high-voltage cell module that is removed from the vehicle. This step directly links the removed part to its original vehicle.
2. Upload Serial Number Information: A picture of the information label from each removed high-voltage cell module must be uploaded to Doc-IT, a system located within Audi Warranty Online. This image must clearly show the module's serial number. The TSB explicitly states that warranty claims will not be paid unless the information label for every removed high-voltage cell module is uploaded to Doc-IT.

Serial numbers for high-voltage modules are typically found on a label directly on the module itself, as illustrated in figures within the original TSB, showing examples from an Audi e-tron Quattro and an Audi Q5 PHEV.

Warranty Information

It is important for owners and technicians to note that TSB 2067544/1 is informational only and does not directly apply to any Audi warranty. However, the documentation steps outlined within it are critical for ensuring that any related warranty claims for high-voltage battery repairs are processed correctly and paid out.

For additional guidance on obtaining necessary photos for HV battery documentation, technicians are advised to refer to Warranty Communication AWA-22-10: HV Battery Photo Documentation.

Additional Information

All part and service references mentioned in this TSB (2067544) are subject to change. Technicians should always consult their Parts Department and/or ETKA for the most current information and parts bulletins. It is also recommended to check the Repair Manual for any fasteners, bolts, nuts, and screws that require replacement during the repair process.
