2024-2025 Audi MIB3 Radio and Settings Loss TSB

Owners of certain 2024-2025 Audi A3, S3, RS 3, and Q3 vehicles may experience an issue where their MIB3 infotainment system fails to save personalized settings. This problem, detailed in Audi Technical Service Bulletin 91 24 44 2074612/2, is attributed to a software fault that causes settings like radio favorites, navigation destinations, and sound adjustments to be lost after the ignition is turned off or the vehicle is parked for an extended period. This TSB supersedes an earlier bulletin, Group 91 number 24-29 dated July 18, 2024, to include a temporary workaround.

Symptoms of Lost MIB3 Settings

Owners affected by this software issue will notice several persistent problems with their vehicle's infotainment system. The primary indication of this fault is that your Audi MIB3 settings lost status will manifest in the following ways:

• "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 that the MIB3 system is not retaining user preferences, requiring owners to re-enter them frequently.

Diagnosis

Audi has identified the root cause of the Audi MIB3 settings lost issue as a software problem within the infotainment system. This is not a hardware defect, meaning that replacing components will not resolve the underlying fault. Workshops can generally reproduce these behaviors under the conditions described by customers.

Important Warnings for Owners

Audi Technical Service Bulletin 91 24 44 2074612/2 includes critical information for both technicians and vehicle owners:

• "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."

These warnings emphasize that attempting to replace parts for this issue is futile and will not be covered under warranty. Owners should be aware that a permanent software solution is currently under development, with an estimated completion date of December 2024, though this is subject to change.

Workaround and Owner Action

While a permanent fix for the Audi MIB3 settings lost problem is being finalized, Audi has provided a temporary workaround. Owners can reset their MMI system to factory settings to temporarily alleviate the issue. This procedure will clear all current settings, allowing for a fresh start.

To perform the MMI reset:

1. From the home screen of your MMI system, select "Settings".
2. Navigate to "System Maintenance".
3. Choose "Restore factory settings".
4. Follow the on-screen instructions to complete the reset.

Be aware that initiating a factory reset will erase all custom settings and device connections. This includes navigation destinations, paired cell phones, connected WiFi devices, and key user settings for Audi connect functions. After the reset, you will need to reconfigure these settings and complete the setup wizard again. The MMI system will restart during this process, which may take a few minutes.

Owners should explain this issue to their dealership, who will create a Pending Service Solutions (PSS) record in the AccessAudi system. This helps Audi track the prevalence of the issue while awaiting the full software implementation.
