2021 Audi e-tron Warning Messages DTC P060C00 C051F00 TSB

Symptoms

Owners of 2021 Audi e-tron vehicles may experience various warning messages appearing in the instrument cluster. These messages can indicate a potential issue with the vehicle's control systems.

Common symptoms include:

• A yellow warning lamp illuminating with the message "Drive fault" displayed in the instrument cluster while driving.
• Numerous warning messages, such as an "ESC message," appearing in the instrument cluster after the engine starts.

These Audi e-tron warning messages are typically sporadic and point to underlying software-related issues within specific control modules.

Fault Codes / DTCs

When diagnosing the symptoms described, technicians may find specific Diagnostic Trouble Codes (DTCs) stored in the vehicle's control modules:

Code	Description	Module
P060C00	Internal Control Module Main Processor Performance (with symptom codes 53312 or 53313)	J841 (electrical drive control module, address word 0051)
C051F00	Multi-axis Acceleration Sensor Module "A" Correlation	J104 (ABS control module, address word 0003)

These codes indicate a performance issue within the electrical drive control module or a correlation problem with the multi-axis acceleration sensor module.

Diagnosis / Trigger Conditions

The root cause of these Audi e-tron warning messages and DTCs is identified as a software anomaly. The issue is sporadic, meaning it may not occur consistently. The presence of DTC P060C00 in the J841 electrical drive control module or DTC C051F00 in the J104 ABS control module confirms the condition.

Repair Procedure Summary

The resolution for these warning messages involves updating the software in the affected control modules. The procedure is as follows:

1. SVM Update Instructions: Follow the detailed instructions provided in TSB 2011732, which outlines the Software Version Management (SVM) operating procedures.
2. Module Update: Update the ABS control module (J104, address word 0003) and the suspension control module (J775, address word 0074) using the SVM action code 74A006. The new software part numbers are 4KE909059AF (version 0242 or higher) for the ABS module and 4KE907777AH (version 2320 or higher) for the suspension module.
3. Basic Settings: After the software update, perform basic settings for the electromechanical parking brake and the tire pressure monitoring system.
4. Post-Update Check: If DTCs persist after the software update, lock the vehicle and wait for the sleep bus mode to activate. Then, read the ABS memory log and delete any remaining DTCs in the J104 ABS control module before reevaluating the vehicle.

This update specifically targets the conditions that trigger the Audi e-tron warning messages and associated DTCs.

Required Tools or Parts

This repair primarily involves a software update, which requires specific software versions and adherence to Audi's Software Version Management (SVM) protocols.

• SVM Operating Instructions: Refer to TSB 2011732 for detailed guidance on performing SVM updates.
• SVM Action Code: 74A006.
• New ABS Software Part Number: 4KE909059AF (replacing 4KE909059AD).
• New ABS Software Version: 0242 (or higher, replacing 0231).
• New Suspension Software Part Number: 4KE907777AH (replacing 4KE907777AM).

Owner Action

If your 2021 Audi e-tron is displaying a yellow "Drive fault" warning lamp, an "ESC message," or any other unusual warning messages in the instrument cluster, it is recommended to schedule an appointment with an authorized Audi dealership. The software update described in TSB 2061908/1 is designed to resolve these issues. This repair is typically covered under the vehicle's warranty for up to 48 months or 50,000 miles, whichever comes first. Certified Pre-Owned (CPO) vehicles may also be covered under specific conditions.
