2022 Audi e-tron GT / RS e-tron GT HUD Flicker TSB

Owners of 2022 Audi e-tron GT and RS e-tron GT models may notice that the street names displayed on their head-up display (HUD) flicker intermittently. This issue is detailed in Audi Technical Service Bulletin (TSB) 90 23 97 2069348/1, issued on January 31, 2023.

Symptoms

Customers report that the street names displayed on the head-up display (HUD) flicker intermittently. This flickering can be distracting and may affect the usability of the HUD system. Workshop diagnostics typically find that no relevant Diagnostic Trouble Codes (DTCs) are stored in the vehicle's systems despite the visible malfunction.

Technical Background

Audi has identified that the intermittent flickering of street names on the HUD is caused by a software-related malfunction. This indicates that the issue is not due to a hardware defect but rather an anomaly in the vehicle's control software.

Important Warnings for High-Voltage Vehicles

For vehicles equipped with high-voltage components, such as the 2022 Audi e-tron GT and RS e-tron GT, specific precautions must be taken during the software update process. To prevent charging of the high-voltage battery during the software update, the high-voltage charging cable must be removed BEFORE entry of the SVM code. Failure to do so could lead to damage to the high-voltage components.

Repair Procedure Summary

The resolution for the 2022 Audi e-tron GT HUD flicker involves updating the software for the Head-Up Display control unit, identified as J898 (address word 0082). This procedure requires the use of a specific SVM (Software Version Management) action code, 82A003.

Before initiating the software update, if the HUD is found to be inoperable, technicians are instructed to reset it by removing fuse SO4 for approximately five minutes and then replacing it. The complete software update process should follow all instructions outlined in TSB 2011732, which covers general Software Version Management (SVM) operating instructions. The update will replace older software versions (e.g., 0101, 0102, 0104 for part numbers 4J3919617 and 4J3919618) with the new software version 0105.

Warranty Information

This software update is covered under Audi's warranty program. The claim type is designated as 110 for vehicles up to 48 months or 50,000 miles. For Certified Pre-Owned (CPO) vehicles, the claim type is G10, requiring verification of the owner. If the vehicle is outside of its warranty period, this Technical Service Bulletin serves as informational guidance only.

The service number for this procedure is 9091, with a damage code of 0039. Labor operations for the software update, including checking for DTCs, are assigned code 0151 0000, with a maximum allowance of 100 TUs (Time Units) as stated on the diagnostic protocol. Diagnostic time (GFF) and road tests before and after the service procedure are allocated no allowance (0 TU).
