2022-2024 Audi A4/A5/Q5 Drive System Faults P060C00 U041600

Symptoms

Owners of certain 2022-2024 Audi A4, A5, and Q5 models may notice specific warnings related to their vehicle's drive system. These include the illumination of the EPC lamp on the dashboard. Additionally, the instrument cluster may display a prominent message stating, "Drive system fault".

Fault Codes (DTCs)

When these symptoms occur, a diagnostic scan of the Engine Control Unit (ECU) will typically reveal one or both of the following Diagnostic Trouble Codes (DTCs):

Code	Description	Module
P060C00	"Internal Control Module Main Processor with Symptom Code DFCC 44160"	Engine Control Unit
U041600	"Invalid Data Received From Vehicle Dynamics Control Module with Symptom Code DFCC 34193"	Engine Control Unit

These codes specifically point to internal software issues within the Engine Control Unit, affecting its main processor and data communication with other vehicle systems. The presence of these codes, particularly the Audi A5 drive system faults P060C00, confirms the underlying software problem.

Technical Background

Audi Technical Service Bulletin 2072710/2 identifies the root cause of these issues as software problems within the Engine Control Unit. These software anomalies lead to the incorrect triggering of the EPC lamp and the "Drive system fault" message, as well as the storage of DTCs P060C00 and U041600.

Important Warnings for Owners

Audi has provided critical guidance for vehicles exhibiting these symptoms:

• Do not replace any components for this condition. Replacing parts will not resolve the underlying software issue and will not address the customer's concern.
• This Technical Service Bulletin is informational only and is not applicable to any Audi Warranty. Owners should be aware that this is not a recall and does not fall under standard warranty claims for repair.

Current Status and Expected Solution

Audi is actively working on a production solution for these software issues. As of the bulletin's revision on February 20, 2024, a definitive fix is still under development. Audi anticipates that a solution will be available by the end of the third quarter of 2024, though this timeline is subject to change.

Dealerships are instructed to explain to customers that no repairs are necessary at this point. They are also required to create a Pending Service Solutions (PSS) record in their internal systems for affected vehicles. This helps Audi track the prevalence of the Audi A5 drive system faults P060C00 and U041600 and ensures that owners can be notified once a permanent solution is released.

Owner Action

If your 2022-2024 Audi A4, A5, or Q5 displays an illuminated EPC lamp or the "Drive system fault" message, and diagnostic scans confirm DTCs P060C00 or U041600, you should contact your authorized Audi dealership. Inform them about the symptoms and the associated fault codes. While no immediate repair is available, your dealer can document the issue by creating a PSS record, ensuring you are in the system for future updates regarding the solution.

This bulletin, identified as 2072710/2, supersedes an earlier version, Technical Service Bulletin Group 01 number 24-06, dated January 12, 2024. The revision includes an updated expected date for the solution.
