2023 Audi Q7/Q8 MIL On: DTC P060C00 ECM Fault

Symptoms

Owners of affected 2023 Audi Q7 and Q8 models may notice that the Malfunction Indicator Lamp (MIL) is illuminated on the dashboard. This is the primary indicator of the underlying issue.

Fault Codes / DTCs

When diagnosing the illuminated MIL, technicians will find a specific Diagnostic Trouble Code (DTC) stored in the Engine Control Module (ECM), identified as -J623- (address word 0001). The relevant fault code is:

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

This DTC P060C00 indicates a performance issue within the ECM's main processor.

Diagnosis / Trigger Conditions

This issue, leading to the Audi Q8 MIL P060C00 fault, is a rare occurrence. It is attributed to the diagnostic software's sensitivity within the Engine Control Module (ECM), specifically the -J623- unit (address word 0001). The DCBD Engine in these models is affected by this condition.

Repair Procedure Summary

Audi Technical Service Bulletin 01 23 00 2072046/2 outlines a software update as the solution for the Audi Q8 MIL P060C00 issue. This TSB supersedes a previous bulletin, 01 23-94, and also replaces Pending Service Solution (PSS) TSB 2067767, which covered similar MIL/EPC light concerns and P060C00 for V6 TFSI engines in MY23 Q7 and Q8 models.

The repair involves updating the software in the ECM, -J623-. Technicians must follow the instructions detailed in TSB 2011732, which covers Software Version Management (SVM) operating procedures. The SVM action code is used to update the ECM to the new software version. For the 2023 Audi Q7, the old software part number 4M0907559T (version 0001) is updated to 4M0907559T (version 0002) using SVM code input 01A255. Similarly, for the 2023 Audi Q8, the old software part number 4M8907559R (version 0001) is updated to 4M8907559R (version 0002) with the same SVM code input 01A255.

Required Tools or Parts

To perform the software update, technicians will need specific diagnostic equipment:

• VAS 6160/VAS 6150: This is a VAS tester that must be running the current version of ODIS (Offboard Diagnostic Information System) on a Windows 10 operating system.

Important Warnings

Warranty coverage for this repair is subject to specific conditions. The repair is typically covered for vehicles up to 48 months or 50,000 miles. For Audi Certified Pre-Owned (CPO) vehicles, coverage is provided after verifying owner eligibility.

They will be able to diagnose the issue, confirm the presence of DTC P060C00, and perform the necessary ECM software update as outlined in Technical Service Bulletin 01 23 00 2072046/2. This software update is designed to resolve the underlying condition.
