2021-2023 Audi e-tron Instrument Cluster Warning TSB

Owners of 2021-2023 Audi e-tron vehicles may encounter unexpected warning messages in their instrument cluster. These messages, such as "Drive fault" or "ESC message," indicate a potential issue within the vehicle's electrical drive or ABS systems. This Technical Service Bulletin (TSB) 2061908/3 from Audi addresses these concerns.

Symptoms

Owners may observe the following issues related to the Audi e-tron instrument cluster warning:

• A yellow warning lamp appearing in the instrument cluster with the message: "Drive fault" while driving.
• Numerous warning messages appearing in the instrument cluster, specifically an "ESC message," immediately after the engine starts.

Fault Codes / DTCs

These instrument cluster warnings are typically accompanied by specific Diagnostic Trouble Codes (DTCs) stored in the vehicle's control modules. Technicians may find the following codes:

Code	Description	Module	Symptom Codes
P060C00	Internal Control Module Main Processor Performance	Electrical drive control module, J841	53312 or 53313
C051F00	Multi-axis Acceleration Sensor Module "A" Correlation	ABS control module, J104

Diagnosis / Trigger Conditions

These DTCs are often stored sporadically within the electrical drive control module (J841) or the ABS control module (J104). The underlying cause has been identified as a software-related issue.

Repair Procedure Summary

To resolve the Audi e-tron instrument cluster warning, a software update is required. The repair involves updating specific control modules using Audi's Software Version Management (SVM) system.

3. Basic Settings: After the software update, basic settings for the electromechanical parking brake and the tire pressure monitoring system (TPMS) must be performed.

Required Tools or Parts

The software update utilizes specific software versions and an SVM action code:

• ABS Control Module (J104): Update from old software part number 4KE909059AD (version 0231) to new software part number 4KE909059AF (version 0242 or higher).
• Suspension Control Module (J775): Update from old software part number 4KE907777AM (version <2320) to new software part number 4KE907777AH (version 2320 or higher).
• SVM Action Code: 74A006.

Important Warnings

If the DTCs persist in the control modules after the software update, follow these additional steps:

1. Lock the vehicle.
2. Wait until the vehicle enters sleep bus mode.
3. Read the ABS memory log and delete any remaining DTCs in the ABS control module (J104).
4. Reevaluate the vehicle's condition.
