Important Warnings and Interim Guidance

Audi has issued specific guidance regarding this condition under Technical Service Bulletin 01 23 39 2066675/2. Owners and technicians should be aware of the following critical instructions:

• Do not replace any components for this condition. Audi explicitly states that replacing parts "will not resolve the customer's concern." This is because a permanent solution is still under development.
• A solution is expected to be available by the end of the 3rd quarter of 2023. However, this timeline is "subject to change."

Service Procedure for Dealerships

For dealerships encountering this issue, the current procedure outlined in the Technical Service Bulletin is informational and focuses on customer communication and record-keeping. Technicians are instructed to explain to the customer that no repairs are necessary at this point, as a solution is still pending. Instead, a Pending Service Solutions (PSS) record must be created. This record is generated through the PSS application, accessible via the Pending Service Solutions link in Access Audi or the Technical Assistance page in Elsa. This process helps Audi track the prevalence of the issue and prepare for the eventual release of a definitive fix.

Warranty Coverage Details

This issue, identified by Service Number 2048 and Damage Code 0040, may be covered under warranty. For new vehicles, coverage typically extends up to 48 months or 50,000 miles.

If your vehicle falls outside of these warranty periods, this Technical Service Bulletin serves as informational guidance only.
