2022 Audi e-tron GT Charging LED Status Light Issue TSB

Symptoms

Owners of 2022 Audi e-tron GT and RS e-tron GT models may observe that the LED status light on the charging socket turns off approximately two minutes after charging begins. The verbatim customer complaint is: "The LED status light on the charging socket turns off after about 2 minutes when charging is active. This does not interrupt charging and the vehicle continues to be charged." This condition, described in Technical Service Bulletin (TSB) 93 22 63 2065701/1, is a visual anomaly and does not affect the actual charging process; the vehicle continues to charge normally.

Fault Codes / DTCs

During workshop diagnosis for the 2022 Audi e-tron GT charging LED issue, technicians will find that there are no relevant fault codes (DTCs) stored in the vehicle's systems. This absence of DTCs indicates that the issue is not a functional fault that triggers diagnostic trouble codes, but rather a software-related display anomaly.

Diagnosis

When investigating the reported issue of the 2022 Audi e-tron GT charging LED turning off, technicians will first reproduce the customer's complaint to confirm the symptom. The diagnostic process involves checking the software part number and version, as well as the Target Data Container information for the High-voltage battery charger (control unit J1050) at address 00C6. This information can be retrieved from the diagnosis log or by using a scan tool to identify the control unit. The current hardware part number is 5QE915684CB, with a hardware version number H74 and software version number 1083. The original Target data container is 4J3909811G with version 0001.

Repair Procedure Summary

To address the 2022 Audi e-tron GT charging LED issue, a software update for the High-voltage battery charger (control unit J1050, address 00C6) is required. The repair procedure involves several key steps:

1. Preparation: Technicians must follow all instructions detailed in TSB 2011732, titled "00 Software Version Management (SVM), operating instructions," which outlines the general process for software updates.
2. Software Update: The High-voltage battery charger (J1050) is updated using the SVM action code 6CA007. This code facilitates the update of the Target data container to the latest available version. Specifically, the update changes the Target data container from 4J3909811G (version 0001) to 4J3909811K (version 0001).
3. Verification: It is important to note that this SVM code will update the Target data container, not the software part number or version directly. Technicians can verify the updated Target data container and its version in the diagnosis log (Figure 1, Position 3 and 4) or by using a scan tool to identify the control unit.

This software update ensures that the charging socket's LED status light functions as intended, remaining illuminated throughout the charging process.
