2021-2022 Audi MIB3 User Data Loss TSB

Owners of various 2021-2022 Audi models equipped with the MIB3 infotainment system may encounter an issue where personalized settings and stored data are sporadically lost. This includes important information such as navigation favorites, home and work addresses, custom tile arrangements, and user-defined HVAC buttons.

This concern is addressed by Audi Technical Service Bulletin (TSB) PSS 91 2062266/8, which supersedes TSB Group 91 number 22-93 dated March 29, 2022. The TSB acknowledges a software bug as the root cause, leading to the loss of user data during vehicle boot-up.

Symptoms

Owners may notice the following symptoms related to the Audi e-tron MIB3 data lost issue:

• "Last destinations, favorites, home/work addresses, tile arrangement, and user-defined buttons, including on the HVAC screen are sporadically lost."
• The problem can occur intermittently and may not be easily reproducible during a dealership visit.

Technical Background

Audi has identified that a software bug within the MIB3 system is responsible for the sporadic loss of user data. This bug can cause certain personalized settings to be deleted when the vehicle's infotainment system starts up.

What Owners Should Know

• Do not replace any components for this condition since this will not resolve the customer's concern. Replacing parts like the MIB3 unit will not fix the underlying software bug.
• Audi states that a permanent software solution is currently under development and was expected to be available in the first quarter of 2023, though this date is subject to change.

Workaround for Lost Data

Audi has implemented a workaround to help mitigate the impact of the Audi e-tron MIB3 data lost problem. As of calendar week 50/21, all affected vehicles have been migrated to a new connect backend that supports "Personalization 2.0."

To utilize this workaround, ensure the following conditions are met:

• The customer must be logged into their myAudi account within the vehicle's MIB3 system.
• There should be no active privacy settings that prevent data synchronization.

When these conditions are met, the vehicle will store favorites and other user-specific settings on the myAudi backend system. While some issues with lost favorites might still occur, they should be recovered from the backend shortly after the MIB3 system connects to the myAudi backend upon startup.

Service Action

If you are experiencing the Audi e-tron MIB3 data lost issue, your Audi dealership will explain that a permanent solution is being developed. No repairs are necessary at this point, and no components should be replaced. Dealerships are instructed to create a PSS (Pending Service Solutions) record for affected vehicles.
