2019-2025 Audi e-tron Charger Diagnostic Address TSB

Revision History

This Technical Service Bulletin, 93 24 70 2063427/8, was issued on July 10, 2024. It supersedes Technical Service Bulletin Group 93 number 24-60 dated June 11, 2024. Previous revisions include Revision 8, which updated measures for non-UNECE software and revised warranty labor operations. Revision 7 (June 11, 2024) also added measures for non-UNECE software and revised warranty. Revision 6 (May 14, 2024) updated the header to include Model Year 2024 and 2025 vehicles, added measures for UNECE software, and revised warranty labor operations.

Symptoms and Workshop Findings

Owners may find that after the high-voltage battery charger control module, identified as J1050 (address word 00C6), has been replaced due to a fault, the new unit no longer reports correctly in the diagnostic scan tool. Instead of appearing under its correct address word 00C6, it reports under address word 8113.

This incorrect reporting prevents the high-voltage system from being restarted. Technicians may observe event memories entered in address 0019, indicating a problem with the high-voltage system activation. The core issue is that the replacement part needs to have its diagnostic address changed to function correctly.

Diagnostic Addresses and Modules Involved

This issue specifically concerns the high-voltage battery charger control module, J1050, which should register under diagnostic address 00C6. When replaced, it may incorrectly register as diagnostic address 8113. The bulletin also references the High-Voltage Battery Charger Control Module 2, J1239, which may also report under address 8113. Event memories related to the high-voltage system not restarting may be found in address 0019.

Repair Procedure Summary

Audi Technical Service Bulletin 93 24 70 2063427/8 outlines the steps for addressing the incorrect diagnostic address reporting for the high-voltage battery charger control module. The repair process varies slightly depending on the software version of the vehicle.

For Software Version 3112 or 3115 (UNECE)

If your vehicle has software version 3112 or 3115, the procedure involves the following steps:

1. Order a new charging unit for the high-voltage battery.
2. Before installation, check the resistance of the charging socket(s) using a VAS 1594 wire harness repair set. Measure pins 24-60 and 41-60 on the 60-pin plug. The measured values should be approximately 2.7k Ohm or 4.7k Ohm, with a tolerance of +/- 5%.
3. Install the battery charger, carefully observing the connection sequence. Figure 1 in the TSB illustrates the labeled connections (1, 2, 3, 4).
4. First, connect electrical connectors -1- and -2-.
5. Connect electrical connector -4- last.
6. After installation, the module must be activated as described in the workshop manual, specifically through Guided Functions: Commissioning 00C6 - Replace control module.
7. If the onboard charger (OBC) still logs address 8113 instead of the correct 00C6, the electrical system configuration must be updated. This is done by pressing "Select self-test" and navigating to "0019 - Data bus on board diagnostic interface – J533" then "0019 - Technical product information" and finally "J533 - Technical Product information 2063053."

For All Other Software Versions

If the concern occurs after component replacement for vehicles with other software versions, proceed using ODIS:

1. Access the High-Voltage Battery Charger Control Module 2, J1239, which will be reporting under 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 correct the diagnostic address.
5. Verify that the high-voltage battery charger control module, J1050, is now reporting under address word 00C6 and that the High-Voltage Battery Charger Control Module 2, J1239, is no longer reporting under address word 8113.
6. Finish the replacement test plan for the J1050 module.
7. If the high-voltage system still cannot be activated again, end the Guided Fault Finding (GFF) process. If a Diagnostic Trouble Code (DTC) is static, restart GFF. Then, work through the DTC entries from the gateway (address 0019) according to the test plan.
8. If the high-voltage system still cannot be activated after these steps, update the electrical system configuration. This is done by pressing "Select self-test" and navigating to "0019 - Data bus on board diagnostic interface – J533" then "0019 - Technical product information" and finally "J533 - Technical Product information 2063053."

Required Tools and Parts

To perform the repair for the Audi e-tron charger diagnostic address issue, specific tools are required:

• VAS 1594: Wire harness repair set, used for measuring resistance.
• VAS 6160/VAS 6150: A VAS tester equipped with the current version of ODIS (Windows 10) for diagnostic and configuration updates.
