Important Warnings for Owners

Audi has issued critical guidance regarding this specific issue, the Audi Q7 Q8 P060C00 fault:

• "Do not replace any components for this condition since this will not resolve the customer's concern." This means replacing parts like the ECM will not fix the underlying problem.
• "Please postpone repairs as there is currently no effective repair for the complaint described by the customer." Owners should not seek repairs for this specific issue at this time.
• "A solution is expected to be available by the end of the 4th quarter of 2023 (subject to change) and that no repairs are necessary at this point." Audi anticipates a fix will be ready by late 2023.
• "If it happens again, please explain to the customer that, an ignition cycle (i.e. shut off vehicle and restart) after coming to rest will restore full vehicle and/or engine performance." In the interim, temporarily resolving the issue may be possible by cycling the ignition.

Technical Background

Audi's Technical Service Bulletin 01 23 49 2067767/4 explains that the root cause of the P060C00 fault is a discrepancy within the engine control unit software. This software anomaly triggers the warning lights and performance issues.

Current Status and Future Solution

Owner Action

If you own a 2021-2023 Audi Q7 or Q8 and experience MIL or EPC warning lights, poor performance, or the P060C00 fault code, it is important to note that a repair is not yet available. Do not authorize component replacements for this issue, as they will not resolve the problem. If the symptoms reappear, performing an ignition cycle (turning the vehicle off and restarting it) may temporarily restore normal vehicle and engine performance. Audi advises postponing repairs until the official software solution is released.
