Symptoms of MIB3 Data Deletion

Owners of affected 2021-2022 Audi vehicles may frequently encounter issues where their MIB3 navigation system intermittently deletes saved information. The most direct and frustrating symptom is that "favorites, home address and stored destinations are deleted" from the system's memory. This problem, stemming from the 005F - Information electronics control unit, can manifest in several specific ways, impacting the overall usability of the infotainment system:

• Navigation Mode Failures: When attempting to select a previously stored destination from memory, the system might display "functionality -> no function," rendering the selection impossible. Destinations may also appear as "functionality -> cannot be selected," or the navigation system might exhibit unusual behavior described as "functionality -> self-adjusting."
• MMI and Screen Display Problems: The screen display, which controls radio, navigation, MMI, and drive device functions, could show "functionality -> no function," appearing blank or unresponsive. Other visual anomalies include the display appearing "functionality -> faulty" or showing "appearance, surface -> color deviation," indicating incorrect colors or graphical glitches.
• Autonomous Data Loss: A critical complaint is that saved destinations in memory are "functionality -> deletes autonomously," meaning they disappear without any user input. This can be accompanied by "functionality -> operation sequence incorrect" when attempting to manage destination memory, leading to confusion and difficulty in setting routes.
• System Unresponsiveness: In more severe instances, the entire radio, navigation, MMI, and drive device functions on the screen display may be "functionality -> stopped," indicating a frozen or completely unresponsive infotainment system.

These issues often occur irregularly, making them challenging to consistently reproduce in a workshop environment. The underlying problem is that the MIB3 system fails to retain previously stored destinations after the vehicle is restarted, leading to the persistent Audi MIB3 navigation data deletion.

Technical Background

Audi has officially acknowledged that the intermittent deletion of saved navigation data within the MIB3 system is directly attributable to a software-related issue. This fault primarily resides within the 005F - Information electronics control unit, which is responsible for managing the vehicle's comprehensive infotainment and navigation functions. To address this, Audi has implemented improved series software in Model Year 2023 vehicles and subsequent models, indicating a permanent fix in newer production runs.

Affected Control Units and Software Versions

The central component implicated in this issue is the 005F - Information electronics control unit. This Technical Service Bulletin applies to a range of software versions across various Audi models, all requiring updates to resolve the Audi MIB3 navigation data deletion. The specific software versions targeted for updates include:

• Audi Q3 MIB3 High: Software versions 33**, 34**, 35**, and 36**.
• Audi A6/A7/Q7/Q8/A8/e-tron/e-tron GT MIB3 Premium: Software versions 34**, 33**, 35**, and 36**.
