Fault Codes / DTCs

The document specifically mentions the following Diagnostic Trouble Codes (DTCs) associated with various issues:

Initial Diagnostic Steps

Before contacting the Audi Helpline, technicians are directed to perform specific initial diagnostic steps and gather information. This includes:

• Worksheet Completion: For many issues, technicians must fill out and attach specific worksheets to the TAC ticket. These worksheets are available via Elsa2Go under "Service References" and "Search v4p."
• Data Logging: For P042000 catalytic converter issues, a GFF Log with all fault codes and completed test plans is required.
• Visual Documentation: For issues like corrosion on the wheelhouse cover plate, front door noise, and speaker grill noise, technicians are asked to provide various photos and videos of the condition before and after any repair attempts.
• Specific Tests: A "Delivery rate test" is needed for P008700 low fuel pressure issues. For "Q5 G31 no com" (U060B00), inspecting harness routing is an initial step.
• Reference Materials: For the airbag light issue with DTCs B101704 and B103604, technicians are referred to TSB 2073566 for instructions.

Repair Guidance

For most of the issues listed, the document emphasizes pre-analysis and information gathering rather than providing a direct repair procedure. The primary guidance is to complete the specified worksheets, collect photographic or video evidence, and perform initial checks before escalating to the Audi Helpline. For the airbag light issue, TSB 2073566 is referenced for specific instructions.

Owner Action
