2021-2022 Audi Q7 & Q8 MIL/EPC Light On, P060C00 DTC

Owners of 2021-2022 Audi Q7 and Q8 vehicles may encounter various warning lamps illuminating in the instrument cluster, accompanied by a noticeable decrease in vehicle performance. These symptoms are often linked to a specific diagnostic trouble code (DTC) indicating an internal control module fault.

Symptoms of an Engine Control Unit Issue

Customers have reported several key indicators pointing to this underlying problem. The most common symptom is the illumination of various warning lamps on the instrument cluster. This includes critical indicators such as the Malfunction Indicator Lamp (MIL) and/or the Electronic Power Control (EPC) warning lamps.

Beyond the visual warnings, drivers may also experience a general degradation in their vehicle's performance. This could manifest as reduced power, hesitant acceleration, or other unusual driving characteristics, impacting the overall driving experience of the Audi Q7 Q8 P060C00 DTC affected vehicles.

Diagnostic Trouble Code (DTC) P060C00

When technicians investigate these symptoms, they typically find a specific Diagnostic Trouble Code (DTC) stored in the Engine Control Module (ECM), identified as J623 (address word 0001). The code is:

• P060C00: Control module internal system fault with symptom 30924.

This DTC points to an internal issue within the engine control unit software. Audi has identified that a discrepancy in this software is the root cause of the warning lights and performance problems.

Important Warning: No Current Repair Available

Audi's Technical Service Bulletin PSS 01 (01 22 23 2067767/1), issued on August 11, 2022, explicitly states that there is currently no effective repair for the complaint described. A solution is under development, and the bulletin will be updated once more information becomes available.

Do not replace any components for this condition, as this will not resolve the customer's concern. This warning is crucial for owners to understand, as attempting repairs or replacing parts prematurely will not fix the underlying software discrepancy and could lead to unnecessary expenses.

What Owners Should Do

If your 2021-2022 Audi Q7 or Q8 is exhibiting these symptoms and has the Audi Q7 Q8 P060C00 DTC, Audi advises postponing any repairs. It is recommended to explain to your service advisor that a solution is being developed and that immediate repairs are not necessary or effective at this point.

Dealerships are instructed to create a PSS (Pending Service Solutions) record. This helps Audi track affected vehicles and ensures that customers are notified once a permanent repair is available. This TSB is informational only and does not apply to any Audi warranty claims for the repair itself, as no repair is yet defined.
