2025 Audi MMI Personal Settings Lost in Guest Profile TSB

Owners of certain 2025 Audi models may notice that their personal settings within the Multi Media Interface (MMI) system are not retained after the vehicle is restarted, especially when using the guest user profile. This issue, where 2025 Audi MMI settings lost after turning off the ignition, is addressed by Audi Technical Service Bulletin (TSB) 2076125/2.

This TSB, released on April 16, 2025, and superseding an initial publication from November 26, 2024, clarifies that the observed behavior is normal for vehicles operating in guest user mode. It provides important information for both technicians and owners regarding the functionality of the MMI system's user profiles.

Symptoms

When the guest user profile is active in the MMI, customers may experience the loss of various personalized settings after the vehicle is restarted or after a bus sleep cycle. This means that specific settings selected by the customer on the MMI may have been lost the next time the ignition is turned on. The affected personal settings include:

• Stored navigation destinations.
• Stored radio stations.
• Audio settings, such as reduced volume during navigation announcements.
• Layout of the driver information display.

Specific complaints noted in the TSB include "audio playback, audio settings -> sound settings" being "not adjustable" or "self-adjusting," "navigation announcement volume" being "self-adjusting," and "destination in destination memory" being "deleted autonomously." Radio operation settings, including automatic and manual station storage, may also show "no function" or "cannot be saved."

Technical Background

The Audi MMI system is designed to start with standard settings whenever the vehicle is operated in guest user mode and completes a bus sleep cycle. This is by design and ensures that no guest user's personal data is permanently stored on the vehicle's system. The 2025 Audi MMI settings lost behavior is a direct result of this design choice.

In contrast, when a personal user profile—either a local profile created on the vehicle or a myAudi user profile—is used, all personal settings are stored and retained for subsequent drives. This applies to both local and myAudi user profiles, ensuring a consistent personalized experience for the primary driver or registered users.

Important Warnings for Owners and Technicians

Audi Technical Service Bulletin 2076125/2 explicitly states critical information regarding this condition:

• Do not perform any repairs. Any attempts to repair this concern may be denied under warranty.
• Instruct the customer that this condition is normal. This is the intended functionality of the MMI system when operating in guest user mode.

This TSB is informational only and does not apply to any Audi Warranty claims, as the behavior is not a defect but a feature of the MMI system's guest mode.

Owner Action

If you are experiencing 2025 Audi MMI settings lost after restarting your vehicle, and you are using the guest user profile, the solution is to switch to a personal user profile. By utilizing either a local user profile created directly on your MMI or logging in with your myAudi account, your personalized settings for navigation, radio, audio, and driver information display will be saved and retained for future use. No dealer visit or repair is necessary for this condition.
