2021 Audi e-tron Navigation Malfunctioning TSB

Owners of certain 2021 Audi models, including the Audi e-tron, may experience issues with their MIB3 navigation system, such as permanent initialization or corrupt map data. This Technical Service Bulletin (TSB) 2062115/6, which supersedes TSB 21-10, provides a detailed procedure for technicians to address these concerns and resolve associated Diagnostic Trouble Codes (DTCs).

Symptoms

Owners may notice the following problems with their vehicle's navigation system:

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

These symptoms indicate a problem with the navigation database, leading to the Audi e-tron navigation malfunctioning.

Fault Codes / DTCs

When the Audi e-tron navigation malfunctioning occurs, one or both of the following Diagnostic Trouble Codes (DTCs) may be stored in the information electronics control module, J794 (address word 005F):

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

Technical Background

Audi has identified that an internal reset during an over-the-air navigation map update can cause the navigation database to become corrupted. This corruption prevents the MIB3 system from properly loading or utilizing the navigation data, leading to the observed symptoms and DTCs.

Repair Procedure Summary

To resolve the Audi e-tron navigation malfunctioning, technicians must reinstall the navigation database using a specific software update process. This involves obtaining the latest navigation database files, preparing a USB drive, and performing an update through the vehicle's MMI system and ODIS diagnostic tool.

1. Obtain Navigation Data: Contact Technical Assistance Center (TAC) to receive a download link and instructions for the current MIB3 navigation database. Download both provided files to the PC's C drive, avoiding Internet Explorer for the download. The files are typically named similar to P0516_MIB3_NA_Q320.MD5, P0516_MIB3_NA_Q320.SHA256, and P0516_MIB3_NA_Q320.SIZE.
2. Prepare USB Drive: Format a 32GB or larger USB drive to the NTFS file system. If the drive is formatted in FAT32, it might not be possible to update the vehicle via the customer update menu.
3. Extract Files: Use 7-zip (available at www.7zip.org if not already installed) to extract the downloaded navigation files. Locate the NAV files on the C drive, select both, and click the extract icon. Open the newly created folder containing the extracted files.
4. Copy to USB: Copy all extracted files directly to the root directory of the NTFS-formatted USB drive. Ensure they are not placed within a single subfolder.
5. Eject USB: Safely eject the USB drive from the computer.
6. Erase Navigation Databank: In the ODIS diagnostic tool, 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. Vehicle Sleep Cycle: End the diagnostic session and allow the vehicle to enter a sleep cycle.
8. Perform MMI Update: Insert the prepared USB drive into the vehicle. Go to the MMI settings section, then MMI settings >> select system maintenance >> software update. The software update should now be available and can be initiated.

Required Tools or Parts

To perform this repair, the following is needed:

• USB Flash Drive, 32GB or larger (locally sourced)

Important Warnings

• Do not discard the USB drive: 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.
• No supervision required: It is not required to keep the vehicle in a service bay or to supervise the update after it has been started.

Warranty Information

This procedure is covered under warranty for qualifying vehicles:

• Claim Type: 110 for vehicles up to 48 months/50,000 miles. G10 for CPO (Certified Pre-Owned) vehicles, verifying owner eligibility.
