2022 Audi e-tron GT Charging Socket LED TSB

Symptoms of the Audi e-tron GT Charging Socket LED Issue

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 after about 2 minutes when charging is active". This condition, described in Audi TSB 93 24 92 2065701/2, does not interrupt the charging process, and the vehicle continues to charge normally. Despite the light turning off, there are no associated fault codes stored in the vehicle's diagnostic system.

Technical Background

Audi has identified the cause of the Audi e-tron GT charging socket LED issue as a software anomaly within the high-voltage battery charger (J1050) control unit. This software glitch causes the LED indicator to extinguish prematurely, even though the charging function remains active and unaffected.

Important Warnings for Service

When addressing the Audi e-tron GT charging socket LED concern, technicians must follow a critical safety procedure. "To prevent charging of the high-voltage battery during the software update, the high-voltage cable is to be removed BEFORE entry of the SVM code on vehicles with high-voltage components. Charging the high-voltage battery during a software update can damage the high-voltage components."

Repair Procedure Summary

To correct the Audi e-tron GT charging socket LED issue, a software update for the high-voltage battery charger (J1050) is required. This procedure involves checking the current software part number (5QE915684CB), hardware version (H74), software version (1083), and Target Data Container (e.g., 4J3909811G) of the J1050 control unit. This information can be viewed via the diagnosis log or a scan tool.

The update is performed using SVM action code 6CA007. Technicians should refer to TSB 2011732, "00 Software Version Management (SVM), operating instructions," for detailed guidance on the SVM update process. It's important to note that the SVM code updates the Target Data Container with the latest available version (e.g., 4J3909811K), rather than directly changing the software part number or version.
