2024-2025 Audi MIB3 Radio & Settings Lost TSB

Owners of certain 2024-2025 Audi A3, S3, RS 3, and 2024 Audi Q3 vehicles may experience issues with their MIB3 infotainment system failing to save settings. Audi Technical Service Bulletin (TSB) 91 24 29 2074612/1, also referred to as PSS MIB3, confirms this is a known software issue and advises that a solution is being developed.

Symptoms of Lost MIB3 Settings

Owners may notice one or more of the following issues with their MIB3 infotainment system:

• "The radio stations saved as favorites during the last trip are no longer stored, after the ignition has been switched off and back on again, or after the vehicle has been parked for an extended period. (In certain cases, only the frequency 88.3 MHz is displayed)."
• "The navigation settings are not saved or are lost after the ignition is switched off and back on. (Last destinations, favorites, etc.)."
• "The sound settings (e.g., balance / fader) are not saved or are lost after switching the ignition off and back on."
• "The setup wizard is displayed repeatedly even though it has already been completed."

These symptoms indicate a problem where the MIB3 system fails to retain personalized preferences and configurations after the vehicle's ignition is turned off or after an extended parking period. The workshop findings confirm that these behaviors are generally reproducible.

Technical Background

Audi has identified the root cause of these issues as a software problem within the MIB3 infotainment system. This means the problem is not due to a faulty hardware component but rather an error in the system's programming that prevents it from properly saving user data.

Important Owner Information

Audi has provided crucial guidance regarding this issue, emphasizing that no immediate repairs should be attempted:

• "No repairs are necessary at this point. Do not replace any components for this condition since this will not resolve the customer's concern."
• "Replacing parts or attempting repairs will not fix the problem. Unjustified labor / replacement parts will be charged back. Invoicing under warranty is not permitted."

This means that attempting to replace parts or perform other repairs will not fix the problem of your Audi MIB3 settings lost and could result in charges not covered by warranty.

What to Expect

Audi's Technical Service Bulletin 91 24 29 2074612/1 states that a production solution for this software issue is not yet implemented. The company is actively working on a fix, with checks for the solution estimated to be completed in December 2024. Owners should be aware that a permanent resolution is still some time away.

Next Steps for Owners

If you are experiencing your Audi MIB3 settings lost, you should contact your authorized Audi dealer. While no repairs are currently available, the TSB instructs dealers to create a PSS (Pending Service Solutions) record. This record helps Audi track the prevalence of the issue and ensures that your vehicle is noted for the eventual software update. Explain to the customer that the implementation of a solution currently being checked and that those checks are estimated to be completed in December 2024.
