2025-2026 Audi MMI Personal Settings Lost in Guest Profile TSB

Audi has released Technical Service Bulletin (TSB) 2076125/3 to address customer inquiries regarding personal settings being lost in the Multi Media Interface (MMI) system when the guest user profile is active. This TSB, released on October 7, 2025, clarifies that the observed behavior of Audi MMI personal settings lost is considered normal operation for the guest profile.

The bulletin applies to various 2025-2026 Audi models, including the A6 e-tron, Q6 e-tron, A5, A6, and Q5. It aims to inform technicians and owners about the expected functionality of the MMI system when different user profiles are utilized, specifically highlighting that the guest profile does not retain customized settings.

Symptoms

Owners may notice that specific MMI settings they have configured are not retained after the vehicle is restarted when the guest user profile is in use. This means that settings selected during one drive cycle may be gone the next time the ignition is turned on. The Audi MMI personal settings lost issue can affect several areas of the infotainment system, leading to a reset of personalized configurations. These include:

• Stored navigation destinations: Any previously saved routes, addresses, or frequently visited locations may disappear from memory.
• Radio stations: Manual or automatic radio station presets might not be saved, requiring the user to re-tune their preferred stations each time.
• Audio settings: Custom sound settings, such as bass, treble, balance, and specific volume levels, including reduced volume for navigation announcements, may revert to default values.
• Layout of driver information display: Personalized display configurations, such as the arrangement of widgets or information shown on the driver's screen, could be reset to the factory default.

Diagnosis / Trigger Conditions

The condition where Audi MMI personal settings lost occurs specifically when the vehicle is operated in guest user mode. According to the TSB, the MMI system is designed to start with standard settings after every bus sleep cycle when a guest user is active. This behavior can be consistently reproduced and verified in a workshop setting.

Workshop findings confirm that personal settings are only stored with lasting effect if the customer uses a personal user profile. This applies to both local user profiles created directly on the vehicle's MMI system and myAudi user profiles linked to an Audi account. In contrast, the guest user profile is intended for temporary use and does not save any customizations.

Technical Background

Audi's technical explanation for this behavior is that when the vehicle is operated in guest user mode, the MMI system initiates with standard settings after every bus sleep cycle. This design ensures that each new guest user experience begins with a clean slate, preventing previous guest users' settings from affecting subsequent temporary users.

Conversely, when a personal user profile—whether a local profile created on the vehicle or a myAudi user profile—is employed, all personal settings are stored and retained. These settings persist even after the vehicle is switched off and restarted, providing a consistent and personalized experience for the registered owner or primary driver.
