2021-2022 Audi MIB3 Navigation Deletes Saved Destinations TSB

Symptoms of Deleted Navigation Data

Owners of 2021-2022 Audi vehicles equipped with the MIB3 navigation system may experience the intermittent or autonomous deletion of saved addresses, favorite locations, and home addresses. This issue means that destinations previously stored in the system are no longer available after the vehicle is restarted or at other random times.

Specific complaints reported include:

• Navigation mode functionality -> no function when selecting destinations from memory.
• MMI screen display functionality -> no function or faulty.
• Destination memory functionality -> deletes autonomously.
• Navigation mode functionality -> cannot be selected or self-adjusting.
• MMI screen display functionality -> operation sequence incorrect or stopped.

The problem can be difficult to reproduce consistently in a workshop setting, as the deletions occur irregularly.

Technical Background

Audi has identified that the intermittent deletion of saved navigation data in the MIB3 system is caused by a software-related issue. This affects the vehicle's information electronics control unit (Diagnostic address 005F). The problem was addressed in production with improved series software for Model Year 2023 vehicles.

Repair Procedure Summary

The repair for the Audi MIB3 deleted destinations issue involves updating the MMI software. The specific update procedure depends on the vehicle's model and current software version.

1. Identify Current Software Version: Technicians must first determine the current 5F software version of the MIB3 system.
2. Apply Initial Update (if necessary):
   • For A4/A5 (model year 2020) with current software 31xx, an initial update to Clu35KD is required, following campaign 91MM.
   • For other models with current software 32xx to 34xx, an initial update to CI37KD is required, following campaign 91DZ.
3. Perform Group-Specific Software Update:
   • Group 3 (Most Models except Q4): For vehicles with current software 36xx (including A4, A5, A6, A7, A8, Q3, Q5, Q7, Q8, e-tron, A3, e-tron GT), the MMI software needs to be updated using TSB 2079133 or TSB 2079134. These updates relate to the connectivity box for MIB3 vehicles (NAR version ST37 or ST37+LSR).
   • Group 4 (Audi Q4): For Q4 models with current software IDS 3.* or IDS 4.*, a combined software update (IDS 3.8.2) is required, as detailed in TSB 2079289.
4. Battery Management: The repair procedure includes a step to charge the battery (operation code 2706 8950) to ensure stable voltage during the software update process.
5. Claim Information: The software update flat rate is 0151 0040, estimated at 60 labor units.
