2021-2022 Audi MIB3: Lost Favorites and Destinations

Symptoms

Owners of 2021-2022 Audi vehicles, including the Audi e-tron, may experience an issue where their MIB3 system sporadically loses saved data. This includes important information such as:

• "Last destinations"
• "Favorites"
• "Home/work addresses"
• "Stored destinations"

Technicians may find that this concern is difficult to reproduce at the dealership because it happens sporadically.

Technical Background

Audi has identified that a software bug within the MIB3 infotainment system is the root cause of this problem. This bug can lead to the loss of user-specific data when the system boots up.

Important Warnings for Owners

• Do not replace components: Audi explicitly states, "Do not replace any components for this condition since this will not resolve the customer's concern." Replacing MIB3 hardware will not fix the underlying software bug.
• Warranty coverage: This Technical Service Bulletin is for informational purposes only and is "not applicable to any Audi Warranty." This means that any diagnostic time or workaround implementation may not be covered under standard warranty terms.

Workaround for Lost Data

To help mitigate the Audi e-tron lost MIB3 data problem, Audi has implemented a workaround leveraging their backend systems. As of Calendar Week 50 of 2021, all affected vehicles have been migrated to a new connect backend that supports "Personalization 2.0."

For this workaround to function, owners must be logged into their myAudi account, and privacy settings should not be actively preventing data storage. When these conditions are met, the vehicle will store favorites and other user-specific settings on the myAudi backend system. While some data loss might still occur, the system is designed to recover these settings from the backend shortly after the MMI system powers on and establishes a connection to the myAudi backend.

Next Steps for Owners

If you are experiencing the Audi e-tron lost MIB3 data issue, Audi advises that a permanent solution is currently under development and is expected to be released in the third quarter of 2022. Until then, the workaround described above is the recommended approach.

Dealers are instructed to explain the situation to customers and create a PSS (Pending Service Solutions) record. This record can be created through the PSS application in AccessAudi (under Related Links >> Service) or via the Technical Assistance page in Elsa.

Revision History

This Technical Service Bulletin has undergone several revisions to provide updated information:

• Revision 5: Service instructions were revised, and the workaround was added.
• Revision 4 (December 8, 2021): The header was revised to correct an Elsa display issue and add software details.
• Revision 3 (October 13, 2021): The header was revised to include additional models and model years, and the expected release date for the permanent solution was updated.
