2019-2025 Audi e-tron Charger Reports Wrong Diagnostic Address

Revision History

This Technical Service Bulletin, 93 24 60 2063427/7, is currently at Revision 7, issued on June 11, 2024. It supersedes TSB Group 93 number 24-54 dated May 14, 2024.

Previous revisions include:

• Revision 6 (May 14, 2024): Revised header to include Model Years 2024 and 2025, revised service measures for UNECE software, and revised warranty labor operations.
• Revision 5 (November 15, 2023): Revised header to include Model Year 2023.

Symptoms

This TSB describes a specific issue that occurs after the high-voltage battery charger control module, identified as J1050 (address word 00C6), has been replaced due to a fault. The primary symptom is that the new J1050 unit no longer reports under its correct diagnostic address 00C6 in the diagnostic scan tool.

Instead, the module incorrectly reports under diagnostic address 8113. This misreporting can prevent the vehicle's high-voltage system from being activated, indicating a communication problem within the vehicle's electrical system related to the Audi e-tron charger address.

Diagnosis / Trigger Conditions

The issue is triggered specifically after the replacement of the high-voltage battery charger control module (J1050). Technicians will identify the problem when the J1050 module, which should register as diagnostic address 00C6, incorrectly appears as address 8113 in the diagnostic scan tool.

For vehicles with software versions 3112 or 3115 (UNECE), the initial replacement of the battery charger might not resolve the issue, necessitating further diagnostic steps. For other software versions, the High-Voltage Battery Charger Control Module 2, J1239, might be observed reporting diagnostic address 8113. The diagnostic process involves checking the charging sockets and measuring their resistance using a specialized VAS 1594 tool. This ensures proper electrical integrity before proceeding with further repairs related to the Audi e-tron charger address.

Repair Procedure Summary

Audi TSB 93 24 60 2063427/7 outlines detailed steps for technicians to correct the diagnostic address of the high-voltage battery charger control module (J1050) in affected Audi e-tron models. This ensures the correct Audi e-tron charger address is recognized by the vehicle's systems.

For Software Versions 3112 or 3115 (UNECE)

1. Order a new charging unit for the high-voltage battery.
2. Check the charging socket(s) and their resistance before installation. Use the VAS 1594 tool to measure resistance on pins 24-60 and 4-61 of the 60-pin plug on the battery charger. Expected values are approximately 2.7k Ohm or 4.7k Ohm, with a tolerance of +/- 5%.
3. Install the battery charger, carefully observing the connection sequence.
4. Connect electrical connectors -1- and -2- first.
5. Connect electrical connector -4- last.
6. Activate the battery charger after installation by following the workshop manual's Guided Functions: "Commissioning 00C6 - Replace control module."
7. If the On-Board Charger (OBC) still logs address 8113 instead of 00C6, update the electrical system configuration by pressing "Select self-test" and navigating to "0019 - Data bus on board diagnostic interface – J533" -> "0019 - Technical product information" -> "J533 - Technical Product information 2063053."

For All Other Software Versions

1. Using ODIS, navigate to "High-Voltage Battery Charger Control Module 2, J1239 (Diagnostic address 8113)."
2. Select "8113 - High-Voltage Battery Charger Control Module 2, functions."
3. Choose "8113 - Change diagnostic address from 8113 to 00C6."
4. Run the test plan, and the scan tool will automatically correct the diagnostic address.
5. Verify that the high-voltage battery charger control module, J1050, now reports under address word 00C6, and the high-voltage battery charger control module 2, J1239, no longer reports under address word 8113.
6. Finish the replacement test plan for the J1050 module.
7. If the high-voltage system still cannot be activated, end Guided Fault Finding (GFF) and restart if any Diagnostic Trouble Codes (DTCs) are static. Work through DTC entries from the gateway (0019) according to the test plan.
8. If the high-voltage system remains inactive, update the electrical system configuration via the path: "Select self-test" -> "0019 - Data bus on board diagnostic interface – J533" -> "0019 - Technical product information" -> "J533 - Technical Product information 2063053."

Required Tools and Parts

To perform this repair, technicians will need the following specialized tools:

• VAS 1594: Wire harness repair set.
• VAS 6160 / VAS 6150: A VAS tester running the current version of ODIS (Windows 10).
