Audi has released Technical Service Bulletin (TSB) 01 23 95 2067767/6, Revision 6, dated November 17, 2023, to address concerns regarding warning lights and performance issues in certain 2019-2022 Audi Q7, Q8, SQ7, SQ8, and RS Q8 models equipped with V6 TFSI engines. This TSB supersedes Group 01 number 23-56, dated April 17, 2023. Owners may experience various warning lamps illuminating in the instrument cluster, including the MIL (Malfunction Indicator Lamp) and/or EPC (Electronic Power Control) warning lamps, alongside symptoms of poor performance. The underlying issue is often identified by the diagnostic trouble code (DTC) P060C00 stored in the Engine Control Module (ECM).

Symptoms of the P060C00 Fault

Owners of affected Audi vehicles, including the 2019-2022 Audi Q7 P060C00 fault, may observe two primary symptoms indicating this issue. The most noticeable sign is the illumination of "various warning lamps are on in the instrument cluster," specifically the MIL and/or EPC warning lamps. In addition to these visual warnings, drivers might also experience "Poor performance" from their vehicle.

Diagnostic Trouble Code (DTC) Details

When diagnosing the issue, technicians will typically find the following diagnostic trouble code (DTC) stored in the Engine Control Module (ECM), identified as -J623- (address word 0001):

This specific P060C00 fault indicates an internal system fault within the control module, pointing to a software-related problem rather than a hardware failure.

Technical Background

According to Audi's technical background, the root cause of these symptoms and the P060C00 fault is a discrepancy in the engine control unit software. This software anomaly leads to the control module internal system fault, triggering the warning lights and performance issues experienced by owners.

Important Warnings and Owner Action

Audi advises owners and technicians to postpone repairs for this condition, as there is currently no effective permanent repair available. It is crucial to understand the following:

• Do not replace any components for this condition, as doing so "will not resolve the customer's concern."
• A solution is expected to be available by the end of the 4th quarter of 2023, though this is "subject to change."
• If the issue recurs, an "ignition cycle" (shutting off the vehicle and restarting it after coming to rest) will temporarily restore full vehicle and/or engine performance.
• Technicians are instructed to create a PSS (Pending Service Solutions) record in the PSS application via AccessAudi or the Technical Assistance page in Elsa to document the customer's complaint.

This guidance is critical to prevent unnecessary parts replacement and ensure owners are aware of the temporary workaround while Audi develops a permanent fix for the Audi Q7 P060C00 fault.

Current Status and Production Solution

Audi states that a production solution is currently under development. The bulletin will be updated once more information regarding the permanent fix becomes available. Until then, the recommended approach is to manage the symptoms as described above.
