2021-2023 Audi Q7/Q8 P060C00 Fault & Warning Lights TSB

Audi has identified a software discrepancy affecting certain 2021-2023 Audi Q7 and Q8 models equipped with the V6 TFSI engine. This issue can lead to various warning lights illuminating on the instrument cluster, including the Malfunction Indicator Lamp (MIL) and Electronic Power Control (EPC) warning lamps. Owners may also experience poor vehicle performance.

This condition is documented in Technical Service Bulletin PSS 01, reference number 01 23 56 2067767/5, which supersedes an earlier bulletin, 01 23-49, dated March 15, 2023. The bulletin indicates that a permanent solution is currently under development by Audi.

Symptoms Owners May Notice

Owners of affected 2021-2023 Audi Q7 and Q8 vehicles may observe the following issues:

• "Various warning lamps are on in the instrument cluster (including MIL and/or EPC warning lamps)"
• Poor performance

Fault Codes (DTCs)

When diagnosed, the Engine Control Module (ECM), specifically J623 (address word 0001), will store a specific diagnostic trouble code (DTC):

Code	Description	Module
P060C00	Control module internal system fault with symptom 30924	ECM

This Audi Q8 P060C00 fault indicates an internal issue within the engine control unit.

Technical Background

Audi has determined that the root cause of the Audi Q8 P060C00 fault and associated symptoms is a discrepancy within the engine control unit software. A production solution to address this software issue is actively being developed.

Important Warnings for Owners

Audi has provided specific instructions regarding this condition to prevent unnecessary repairs and costs:

• Do not replace any components for this condition since this will not resolve the customer's concern. This is a critical warning, as replacing parts will not fix the underlying software issue and could lead to wasted expense.

What Owners Should Do

If you experience the MIL/EPC warning lights or poor performance related to the Audi Q8 P060C00 fault, Audi advises the following:

• Postpone repairs: There is currently no effective repair available for this complaint. A solution is expected to be available by the end of the 4th quarter of 2023, though this timeline is subject to change.
• Temporary resolution: If the issue occurs, an ignition cycle (turning the vehicle off and then restarting it) after coming to rest will typically restore full vehicle and engine performance.
• No immediate action required: No repairs are necessary at this point, as the issue is related to software that is being updated.

Next Steps for Dealers

For dealerships, the Technical Service Bulletin PSS 01 (2067767/5) instructs technicians to create a Pending Service Solutions (PSS) record. This record should be made in the PSS application via AccessAudi (under Related Links >> Service) or through the Technical Assistance page in Elsa. This helps Audi track the occurrences of the Audi Q8 P060C00 fault while the permanent software solution is being developed.
