2023 Audi Q7/Q8/SQ7/SQ8/RS Q8 MIL On: DTC P060C00

Symptoms

Owners of 2023 Audi Q7, SQ7, Q8, SQ8, and RS Q8 vehicles may notice the Malfunction Indicator Lamp (MIL) illuminated on their dashboard. This indicates a potential issue with the vehicle's engine control system.

Fault Codes / DTCs

When diagnosing the illuminated MIL, workshops may find the following Diagnostic Trouble Code (DTC) stored in the Engine Control Module (ECM):

Technical Background

Audi Technical Service Bulletin 01 23 94 2072046/1 explains that the illumination of the MIL and the storage of DTC P060C00 is a rare occurrence. It stems from the diagnostic software within the Engine Control Module (ECM), specifically -J623- (address word 0001), being overly sensitive. This sensitivity can incorrectly trigger the fault code, leading to an Audi Q8 P060C00 MIL on condition, even when there is no actual hardware malfunction.

Repair Procedure Summary

The resolution for the illuminated MIL and DTC P060C00 involves updating the software of the Engine Control Module (ECM). This TSB, 01 23 94 2072046/1, supersedes previous Pending Service Solution (PSS) TSB 2067767, which addressed similar issues for MY22 and MY23 Q7 and Q8 models. The update process requires following the instructions outlined in TSB 2011732: 00 Software Version Management (SVM), operating instructions. Technicians will use a specific SVM action code, such as 01A255 for the 2023 Audi Q7 and Q8, to update the ECM (-J623-, address word 0001) to the latest software version (e.g., 0002 or higher). This new software specifically addresses the diagnostic sensitivity causing the Audi Q8 P060C00 MIL on condition.

Required Tools

To perform the software update, technicians will need a VAS tester, specifically the VAS 6160/VAS 6150, running the current version of ODIS (Windows 10) diagnostic software.
