This 'MIL on' condition is often accompanied by the storage of DTC P060C00, indicating an 'Internal Control Module Main Processor Performance' issue within the ECM. In some cases, drivers might also observe an 'EPC light on' or "various warnings or poor performance" messages, all stemming from the same underlying Audi Q8 P060C00 fault.

The primary diagnostic trouble code associated with this condition is:

Code	Description	Symptom Code
P060C00	Internal Control Module Main Processor Performance	30924

Technical Background and Diagnosis

Audi has identified that the DTC P060C00 is stored in the Engine Control Module (ECM), specifically the -J623- unit (address word 0001). This is considered a rare occurrence, stemming from the sensitivity of the diagnostic software within the ECM. The software's sensitivity can incorrectly trigger the fault code, leading to the illumination of the MIL.

Repair Procedure Summary
