2021-2022 Audi MIB3 Navigation Data Loss TSB

Owners of certain 2021-2022 Audi vehicles equipped with the MIB3 infotainment system may experience an issue where their saved navigation data, such as favorites, home addresses, and other stored destinations, is sporadically lost. This problem, identified in Technical Service Bulletin (TSB) 91 22 93 2062266/7, points to a software bug as the root cause of the Audi MIB3 navigation data loss.

Symptoms

If you own a 2021-2022 Audi vehicle with MIB3, you might notice the following:

• Your "last destinations" are missing.
• Saved "favorites" in the navigation system have disappeared.
• Your "home address" and "work address" settings are no longer stored.

This data loss can occur sporadically, making it difficult to reproduce at a dealership during a service visit.

Technical Background

Audi has identified that a software bug within the MIB3 system is responsible for the loss of user data. This bug can cause the system to lose stored information during the vehicle's boot-up process.

Important Warnings

Audi explicitly states that technicians should not replace any components for this condition. Replacing parts will not resolve the customer's concern, as the issue stems from a software bug.

Workaround

While a permanent software solution is still under development and expected in the third quarter of 2022 (subject to change), Audi has implemented a workaround leveraging the myAudi backend system. As of Calendar Week 50/21, all affected vehicles have been migrated to a new connect backend that supports "Personalization 2.0".

If you are logged into your myAudi account and do not have privacy settings active, your vehicle will store favorites and other user-specific settings on the myAudi backend system. Should you still experience the Audi MIB3 navigation data loss, your lost data will be recovered from the backend shortly after the MMI system powers on and connects to the myAudi backend.

Next Steps for Owners

If you are experiencing the Audi MIB3 navigation data loss, you should inform your Audi dealership. They will create a PSS (Pending Service Solutions) record in their system, which helps Audi track the prevalence of the issue and ensures you are accounted for when a permanent solution becomes available. There is no repair required at this time, as the workaround is in place and a software update is pending.
