2022-2025 Audi A4/Q5 Drive System Fault P060C00 U041600 TSB

Audi has released Technical Service Bulletin (TSB) 2072710/6, titled "01 PSS Engine control unit drive system faults P060C00, and U041600," addressing specific engine control unit issues in certain 2022-2025 Audi A4 and Q5 models. This bulletin, released on June 12, 2025, is a Pending Service Solution (PSS) indicating that a fix is under development.

Owners of affected vehicles may experience dashboard warnings related to the engine's drive system. This TSB provides guidance for technicians on how to handle customer concerns while Audi works on a permanent solution for the Audi P060C00 U041600 issue.

Symptoms

Owners of 2022-2025 Audi A4 and Q5 vehicles may observe the following symptoms:

• "The EPC Lamp lights up."
• "Drive system: fault" appears in the instrument cluster.

These warnings indicate a potential issue with the engine's electronic power control or the overall drive system, prompting concern from vehicle owners.

Fault Codes / DTCs

When these symptoms occur, technicians performing diagnostics may find the following Diagnostic Trouble Codes (DTCs) stored in the Engine Control Unit (-J623-, address word 0001):

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

These codes point to internal software communication or data integrity issues within the engine's electronic systems, specifically related to the main processor and communication with the vehicle dynamics control module.

Technical Background

The root cause of the "Drive system: fault" messages and the associated DTCs, including the Audi P060C00 U041600 codes, has been identified as software issues within the Engine Control Unit. Audi is actively working on a production solution to address these underlying software problems.

Important Warnings

Audi has issued critical advisories for both owners and technicians regarding this condition:

• "Do not replace any components for this condition since this will not resolve the customer's concern." This is crucial, as replacing parts will not fix the software-related problem and could lead to unnecessary costs.
• "In many cases, the complaint is fixed after an ignition cycle." Owners might find that the warning clears after restarting the vehicle, though the underlying issue remains.

Owner Action / Next Steps

If your 2022-2025 Audi A4 or Q5 exhibits the EPC lamp illumination or the "Drive system: fault" message with the Audi P060C00 U041600 DTCs, no immediate repair is necessary. Audi expects a solution to be available in Q3 of 2025, though this timeline is subject to change. The symptoms are not expected to affect the vehicle's performance.

Owners should visit an authorized Audi dealer to have a Pending Service Solution (PSS) record created in the AccessAudi system. This ensures that your vehicle's issue is documented and you will be notified when the permanent software update becomes available.

TSB 2072710/6 has undergone several revisions. The current version, Revision 6, includes updated information regarding the expected release date for the solution and revised conditions. Earlier revisions (5 and 4) focused on updating the header and adding model years.
