2021-2022 Audi Q8 / A7 MIL/EPC Light and P060C00 DTC TSB

Symptoms

Owners of affected 2021-2022 Audi Q8 and A7 vehicles may observe several indicators of this issue. The most common complaints include the illumination of various warning lamps in the instrument cluster. This often specifically involves the Malfunction Indicator Lamp (MIL) and/or the Electronic Power Control (EPC) warning lamps. In addition to these visual warnings, drivers might also experience a noticeable decrease in vehicle performance.

Fault Codes / DTCs

When diagnosing this condition, workshops have consistently found a specific Diagnostic Trouble Code (DTC) stored in the Engine Control Module (ECM), identified as J623 (address word 0001). The code indicates an internal system fault within the control module.

This DTC, P060C00, points directly to an internal issue within the engine control unit's system, which is the root cause of the observed symptoms like the illuminated warning lights and reduced performance in the Audi Q8 P060C00 scenario.

Technical Background

Audi has identified that the underlying cause for the MIL/EPC warning lights and poor performance, accompanied by DTC P060C00, is a discrepancy within the engine control unit software. This software anomaly prevents the engine control module from functioning correctly, leading to the various symptoms reported by vehicle owners. The manufacturer is actively working on a resolution for this software-related problem.

Important Warnings

Audi Technical Service Bulletin PSS 01 (2067767/3) explicitly states that there is currently no effective repair available for the complaint described. It is crucial for both owners and technicians to understand that no repairs are necessary at this point and that replacing any components for this condition will not resolve the customer's concern.
