2021-2022 Audi MIB3 Software Update for Lost Favorites and Blue Screen

This Technical Service Bulletin (TSB) addresses various software-related issues affecting the MIB3 infotainment system in certain 2021-2022 Audi vehicles. Owners may experience problems with saved navigation data, screen display, or system startup.

Symptoms

Owners of affected Audi vehicles may observe the following issues with their MIB3 infotainment system:

• "Saved addresses (including the home address), favorites, last destinations, and/or icon and shortcut order are lost sporadically."
• In rare cases, "the screen may turn completely blue until a bus sleep, or an MMI reboot is performed."
• For MY22 Audi Q3 models specifically, "The MMI gets stuck on the welcome screen while loading user information from the backend on startup."

Diagnosis and Trigger Conditions

These symptoms are typically caused by a software-related issue within the MIB3 system. Importantly, workshop findings indicate that "No relevant DTCs are stored" in conjunction with these specific complaints. This means traditional diagnostic trouble codes will not appear, pointing directly to a software malfunction rather than a hardware failure.

Important Warnings

Before any software update is performed, technicians must ensure all prerequisites are met. For 2021 Model Year vehicles, Safety Recall 91DZ must be completed prior to performing the update described in this TSB. Additionally, for 2020 Model Year vehicles, an update according to TSB 2067021 (addressing various malfunctions including B129B11, B129C22, B123B13, B123C13 or B200000) is required.

Repair Procedure Summary

The resolution for these MIB3 infotainment system issues is a software update. The procedure involves checking the current software version of the information electronics -J794- (address word 005F). If the software version is lower than 3696, the update should proceed.

The update can be performed using one of two methods:

1. Automated Update: Utilizing the ODIS Tester for an automated process.
2. Manual Update: A manual update can be performed if there are SVM code or server issues, following instructions from TSB 2060523: "91 MIB3 Software Update Instructions."

The appropriate SVM code must be used based on the vehicle model. For A3, A4, A5, Q3, and Q5 models, the SVM code is CL35MH13P3853, associated with SD Creator Part Number 8W0906961BB. For A6, A7, A8, Q7, Q8, e-tron, and e-tron GT models, the SVM code is CL35MPR3P3853, associated with SD Creator Part Number 8W0906961AT.

The entire update process, including the software update and SVM work, is estimated to take approximately 30-60 minutes.

Required Tools or Parts

To perform the MIB3 software update, the following equipment and parts are necessary:

• ODIS Tester: For diagnostic and programming functions.
• SVM code: Specific to the vehicle model for the update.
• MIB3 Software update on USB Flash Drive: This can be obtained via a USB Flash Drive (part numbers listed below) or downloaded from MirrorServer using the SD Creator Program.
  • USB Flash Drive (for A3/A4/A5/Q3/Q5): Part Number 8W0906961BB (Quantity: 01, Shop tool)
  • USB Flash Drive (for A6/A7/A8/Q7/Q8/e-tron/e-tron GT): Part Number 8W0906961AT (Quantity: 01, Shop tool)

Additional Technical Service Bulletins that provide necessary instructions for this procedure include TSB 2011732 (00 Software Version Management (SVM), operating instructions), TSB 2060523 (91 MIB3 Software Update Instructions), and TSB 2047812 (00 SD Creator: how to set up and use the SD Creator for obtaining vehicle software updates via the MirrorServer).

Warranty Information

This software update is covered under warranty for vehicles up to 48 months or 50,000 miles. For Audi Certified Pre-Owned (CPO) vehicles, coverage falls under G10, requiring owner verification. If the vehicle is outside of warranty, this bulletin serves as informational guidance only.
