2022-2024 Audi A4/A5/Q5 Engine Faults P060C00, U041600

Symptoms You Might Notice

Owners of affected 2022-2024 Audi A4, A5, and Q5 models may observe several warning indicators related to engine control unit faults. These symptoms are often intermittent and, in many cases, the complaint might resolve itself after an ignition cycle. However, they indicate an underlying software issue.

Specifically, customers have reported the following conditions:

• The "EPC lamp lights up"
• A "Drive system fault" message appearing in the instrument cluster
• The TPMS (Tire Pressure Monitoring System) light illuminating
• The ESC (Electronic Stability Control) light illuminating

Diagnostic Trouble Codes (DTCs)

When these symptoms occur, a workshop diagnosis may reveal specific Diagnostic Trouble Codes (DTCs) stored in the Engine Control Unit (-J623-), which is identified by address word 0001. These codes point to internal software issues within the ECU.

Code	Description	Module
P060C00	"Internal Control Module Main Processor with Symptom Code DFCC 44160"	Engine Control Unit (-J623-)
U041600	"Invalid Data Received From Vehicle Dynamics Control Module with Symptom Code DFCC 34193"	Engine Control Unit (-J623-)

Technical Background

Audi has identified that the root cause of these issues, including the Audi A5 P060C00 U041600 faults, stems from software problems within the Engine Control Unit. This Technical Service Bulletin (TSB) 2072710/3, which supersedes previous bulletin 24-09, highlights that a permanent software solution is currently under development to address these concerns.

Revision History

Technical Service Bulletin 01 24 18 2072710/3 has undergone several revisions to provide updated information:

• Revision 3 (April 5, 2024): The Condition section was revised with updated customer statements, and the Service section was updated with customer explanations.
• Revision 2 (February 20, 2024): The Service section was revised to include an updated expected date for the solution.
• Revision 1 (January 12, 2024): This was the initial publication of the bulletin.

Important Warnings for Owners

Audi has provided critical guidance for owners and technicians regarding these engine control unit faults. It is crucial for owners to understand the following:

• Do not replace any components for this condition. Audi explicitly states that replacing parts "will not resolve the customer's concern" because the issue is software-related. This prevents unnecessary repairs and costs.
• While multiple warning lights may appear on the dashboard, these issues are currently not expected to "affect the performance of the vehicle."
• In many cases, the complaint might be temporarily fixed after an ignition cycle, but the underlying software issue remains.

Current Status and Next Steps

Audi is actively working on a software solution for the engine control unit issues that trigger DTCs like P060C00 and U041600. This solution is anticipated to be available by the end of the third quarter of 2024, though this timeline is subject to change. For now, this TSB is informational only and does not fall under standard Audi Warranty procedures.

If your 2022-2024 Audi A4, A5, or Q5 exhibits the symptoms described, such as the Audi A5 P060C00 U041600 fault, it is recommended to visit an authorized Audi service center. Technicians are instructed to create a Pending Service Solutions (PSS) record in the PSS application via AccessAudi (under Related Links >> Service). This process helps Audi track the prevalence of the issue and gather data while the permanent fix is being developed. No repairs are necessary at this point, as the solution is still pending.
