Symptoms

Owners of affected 2020-2021 Audi vehicles may observe the following symptoms related to their navigation system:

• The navigation system is "permanently initializing."
• The navigation map is "corrupt or incomplete."

These symptoms indicate a problem with the MIB3 navigation database, preventing the system from functioning correctly.

Fault Codes / DTCs

When diagnosing the Audi MIB3 navigation malfunctioning issue, technicians may find one or both of the following Diagnostic Trouble Codes (DTCs) stored in the information electronics control module, J794 (address word 005F):

Code	Description	Module
B126CF0	Navigation system Navigation database malfunctioning	Information Electronics Control Module, J794
B126CF1	Navigation database not available	Information Electronics Control Module, J794

Diagnosis / Trigger Conditions

The root cause of the Audi MIB3 navigation malfunctioning is an internal reset that occurs during an over-the-air navigation map update. This reset can lead to the navigation database becoming corrupted, rendering the system inoperable or displaying incorrect information.

Important Warnings

Audi has provided specific instructions for technicians to ensure a smooth repair process and prevent unnecessary steps:

• Please keep the USB flash drive with the navigation data as a workshop tool. It is not required to call into TAC or re-download the navigation data if the USB flash drive has already been created and is available.
• It is not required to keep the vehicle in a service bay or to supervise the update after it has been started.

Repair Procedure Summary

The repair for the Audi MIB3 navigation malfunctioning involves reinstalling the navigation database using a specific procedure. This process requires a technician to:

1. Contact the Technical Assistance Center (TAC) to receive a download link and instructions for the current MIB3 navigation database.
2. Download both necessary files from the provided link to the PC's "C drive," avoiding the use of Internet Explorer.
3. Obtain a 32GB or larger USB drive and format it to "NTFS." If the drive is formatted in FAT32, it may not be possible to update the vehicle.
4. Use 7-zip (or similar software) to extract the downloaded NAV files. The extracted files should be placed directly onto the root of the formatted USB drive, not within a single folder.
5. Eject the USB drive safely.
6. Using the ODIS diagnostic system, navigate to Guided Fault Finding/Guided Functions. Select and execute the test plan: "Self test >> Diagnostic capable system >> 005F - Information Electronics Control Module 1 -J794- (MIB 2+ or MIB 3) >> 005F - Information Electronics 1, functions / 005F – Basic Setting >> Erase navigation databank."
7. End the diagnostic session and allow the vehicle to enter a sleep cycle.
8. Insert the prepared USB drive into the vehicle. Access the MMI settings section and select "MMI settings >> system maintenance >> software update."
9. The software update should then be available for installation.
