2021 Audi MIB3: Lost Destinations and Favorites TSB

Owners of certain 2021 Audi models equipped with the MIB3 infotainment system may encounter an issue where their saved navigation data, including last destinations, favorites, and home/work addresses, are sporadically lost. This concern is detailed in Audi Technical Service Bulletin (TSB) 91 21 17 2062266/2, issued on August 2, 2021.

This bulletin supersedes an earlier version, TSB Group 91 number 21-68, dated February 17, 2021, indicating ongoing efforts to address the problem. The issue, commonly referred to as the Audi MIB3 destinations lost problem, can be frustrating for drivers relying on their vehicle's navigation system.

Symptoms of Lost MIB3 Data

Customers have reported that their MIB3 infotainment system sporadically loses important user data. The primary symptoms include:

• "Last destinations" disappearing from the navigation history.
• Saved "favorites" being deleted.
• Pre-set "home/work addresses" vanishing.

Dealerships may find that the concern is not always reproducible during diagnostics, as the data loss happens sporadically. This makes it challenging to diagnose without a clear understanding of the underlying cause.

Why Your Audi MIB3 Data is Disappearing

According to Audi's technical background information, the root cause of the Audi MIB3 destinations lost issue is a software bug. This bug can lead to some user data being lost specifically during the system's boot-up process. Audi is actively working on a permanent solution for this software defect.

Important Warnings for Owners

Audi has provided specific instructions for dealerships regarding this issue, which are crucial for owners to understand:

• Do not replace any components for this condition since this will not resolve the customer's concern. This means that replacing parts of the MIB3 system will not fix the software bug and would be an unnecessary expense if not covered under warranty.

What to Expect for a Solution

Audi has indicated that a production solution for the software bug is currently under development. Owners should be informed that a fix is anticipated to be available in the first quarter of 2022. Until then, no repairs are necessary, as replacing components will not resolve the issue.

Dealerships are instructed to explain the forthcoming solution to customers. Additionally, they are required to create a PSS (Pending Service Solutions) record for affected vehicles. This record helps Audi track the prevalence of the Audi MIB3 destinations lost problem and ensures that customers are noted for future updates.

This TSB is informational and does not directly apply to any Audi Warranty claims, as it primarily communicates a known issue and a pending solution rather than a repair procedure.
