2022 Audi e-tron GT HUD Fault DTC B200043 TSB

Audi has released Technical Service Bulletin (TSB) 90 22 62 2064963/3 to address issues with the Head-Up Display (HUD) in certain 2022 Audi e-tron GT and RS e-tron GT models. This TSB specifically targets vehicles that may store Diagnostic Trouble Code (DTC) B200043, indicating a "Control Module Faulty" condition within the HUD system. The bulletin, dated May 11, 2022, supersedes a previous TSB, Group 90 number 21-24, from November 17, 2021, and provides an updated software solution.

Symptoms

Owners of affected 2022 Audi e-tron GT and RS e-tron GT vehicles may notice that the "head-up display (HUD) is not working." In some cases, there might be no immediate customer concern, with the issue only being identified by technicians during pre-delivery inspection (PDI) or other diagnostic work.

Fault Codes / DTCs

When diagnosing the issue, workshop findings will typically show the following Diagnostic Trouble Code (DTC) stored in the Head-Up Display (HUD) control module, identified as J898 (address word 0082):

Code	Description
B200043	Control Module Faulty

This DTC indicates a software bug within the HUD system, which the TSB aims to correct.

Important Warnings

For vehicles equipped with high-voltage components, such as the Audi e-tron GT, a critical safety warning applies during the software update procedure. To prevent potential damage to high-voltage components from the charging of the high-voltage battery, the high-voltage cable must be removed BEFORE entering the SVM code. Failure to do so could lead to damage to the high-voltage system.

Repair Procedure Summary

The repair for the 2022 Audi e-tron GT HUD fault primarily involves a software update to the Head-Up Display control module (J898). The general steps are:

1. Initial Check: If the HUD is completely inoperable, technicians should first attempt a reset by removing fuse SO4 for approximately five minutes, then reinstalling it.
2. SVM Instructions: All instructions detailed in TSB 2011732: 00 Software Version Management (SVM), operating instructions, must be followed carefully.
3. Software Update: The HUD control module (J898) is updated using a specific SVM action code. This update replaces older software versions with the latest available.

Required Tools or Parts

The software update requires the use of specific software part numbers and versions, along with a designated SVM action code. The TSB specifies the following details for the update:
