2021-2026 Audi e-tron HV Module Documentation TSB

Why Proper Documentation of HV Modules is Crucial

This Technical Service Bulletin (TSB) 93 25 48 2067544/5 emphasizes the critical importance of documenting high-voltage cell modules when they are replaced in Audi Hybrid and e-tron vehicles. The primary purpose of this documentation is to ensure proper traceability in the event of an analysis request or for the recycling of these high-voltage components. Audi AG has a strong interest in analyzing replaced high-voltage modules to improve future designs and processes.

Accurate and complete Audi e-tron cell module documentation facilitates efficient processing and organized transport of these specialized parts. This procedural TSB is vital for environmental responsibility and maintaining the integrity of Audi's high-voltage systems.

When Documentation is Required

Documentation is required whenever high-voltage cell modules of the high-voltage battery are replaced as part of any repair work on the high-voltage system. This applies to a wide range of Audi models, specifically Hybrid and e-tron vehicles from model years 2016 to 2025 according to the TSB, which includes the 2021-2026 Audi e-tron and other models linked by NHTSA.

Mandatory Documentation Steps for Technicians

When a high-voltage module is replaced, technicians must perform the following two steps:

1. Step 1: Document VIN on the Removed Module. Using a waterproof pen, the chassis number (VIN) of the vehicle from which the high-voltage cell module was removed must be documented on every removed high-voltage module.
2. Step 2: Document Serial Number. The serial number of every removed high-voltage cell module must be documented by uploading a picture of its information label to Doc-IT, located within Audi Warranty Online. The serial numbers are found directly on the module's label, as illustrated in Figure 1 (Audi e-tron Quattro cell module) and Figure 2 (Audi Q5 PHEV cell module).

It is crucial to note that the warranty claim for the repair will not be paid until the information label is successfully uploaded to Doc-IT for every high-voltage cell module removed. This underscores the importance of diligent Audi e-tron cell module documentation for service centers.

Important Warnings and Disposal Guidelines

Audi provides strict guidelines regarding the handling and disposal of 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 instructed to "Contact importer before disposing of high-voltage modules" and "Do not dispose of removed high-voltage modules without prior consultation." This ensures proper channels are followed for analysis and recycling.
• The TSB also includes a general "DANGER" advisory, highlighting the inherent risks associated with high-voltage systems.

What Owners Should Know

If your 2021-2026 Audi e-tron or Hybrid vehicle requires high-voltage cell module replacement, it's important to be aware of these mandatory documentation procedures. While this TSB is primarily for technicians, understanding its requirements can help ensure your service center properly records and processes the repair. This ensures the repair is properly recorded and processed, especially for warranty claims. Proper Audi e-tron cell module documentation is vital for the long-term integrity and serviceability of your vehicle's high-voltage system.
