2025 Audi Digital Key Sharing Not Working TSB

Owners of certain 2025 Audi models may encounter a problem where the 2025 Audi digital key sharing function does not work as expected. This issue, detailed in Audi Technical Service Bulletin (TSB) 2077208/2, specifically affects the ability to share the digital key (MDK - mobile device key) with other users.

This bulletin, released on June 24, 2025, is a Pending Service Solution (PSS) indicating that a fix is under development. Audi has identified that the core problem lies in a limitation within the backend system, which currently restricts the number of digital keys to the primary key user.

Symptoms

Owners experiencing this issue will notice that the 2025 Audi digital key sharing feature fails to function. The primary symptom is that the "digital key (MDK - mobile device key) cannot be shared with other users" or the "shared key does not work." This means that even if you attempt to share your digital key, the recipient will not be able to use it to access or operate the vehicle.

Technical Background

Audi's investigation into the digital key sharing problem has revealed that the limitation stems from the backend system. Currently, the system is configured to limit the number of active digital keys to the key user. This technical constraint prevents the successful sharing of the digital key with additional users, leading to the reported malfunction.

Important Warnings for Owners

Audi has issued a critical advisory regarding this condition:

• "Do not replace any components for this condition since this will not resolve the customer's concern." This means that attempting to replace parts like the digital key module or other related hardware will not fix the problem, as it is a software/backend limitation.
• This TSB (2077208/2) is informational only and is not applicable to any Audi Warranty. Owners should understand that this is a known issue with a pending software solution, not a defect requiring immediate repair under warranty terms.

What Owners Should Do

If you are experiencing issues with 2025 Audi digital key sharing, Audi advises the following:

1. No Immediate Repair Needed: You should be informed by your Audi service center that a solution is expected to be available by the end of the third quarter of 2025. This timeline is subject to change, but no physical repairs are necessary at this point.
2. Do Not Replace Components: As stated in the TSB, replacing any components will not resolve the digital key sharing issue. Save yourself potential unnecessary costs or service time.
3. Dealer Documentation: Your Audi dealer is instructed to create a Pending Service Solutions (PSS) record in their system. This helps Audi track the prevalence of the issue and ensures that your vehicle is noted for the upcoming software solution.

This issue is not a safety concern but rather a functionality limitation that Audi is actively working to resolve through a software update. Owners should monitor official Audi communications for updates regarding the availability of the solution.
