Common Issues and Symptoms

This analysis list covers several distinct problems, each with specific diagnostic and preliminary repair steps.

Leaking Timing Chain Cover Gasket

• Affected Models: 2022-2025 Audi Q5 models equipped with the DPVA engine.
• Symptoms: Visible fluid leaks originating from the timing chain cover gasket area.
• Diagnosis: Technicians must capture clear photos and video footage of the active leak. This documentation is crucial before contacting the Technical Assistance Center (TAC) for further guidance.

ECM DTC P060600 "ECM/PCM Processor" Fault

• Affected Models: 2022-2025 Audi A4, A5, Q5, and Q7 models with 2.0L engines only.
• Symptoms: The presence of Diagnostic Trouble Code (DTC) P060600, indicating an issue with the Engine Control Module (ECM) or Powertrain Control Module (PCM) processor.
• Diagnosis: If the DTC P060600 is present, technicians should attempt to clear the fault. After clearing, a test drive of at least 20 miles is recommended to determine if the fault can be reproduced. Further instruction requires contacting TAC.
