2021-2023 Audi MIB3 MMI Software Update TSB

Audi has released Technical Service Bulletin (TSB) 2079133/2 to address various software-related issues affecting the MIB3 infotainment system and emergency call functionality in certain 2021-2023 models. This TSB outlines a software update for the emergency call module (0075) and information electronics (005F) to resolve these concerns. Owners experiencing problems with their MMI system or an "Emergency call fault" message should be aware of this update.

Symptoms

Owners may experience a range of issues related to the MIB3 infotainment system and connectivity. These can include:

• Problems with navigation mode, radio operation, and general MMI functions.
• Malfunctions with screen settings, instrument cluster displays, and telephony.
• Issues with audio playback and settings, media playback, and audio/video/television functionality.
• An "Emergency call fault" message displayed in the instrument cluster.
• Problems with Telematics, online services, and infotainment system operation via the multifunction steering wheel.
• Difficulties controlling infotainment with buttons, controls, or speech input.

These symptoms are typically linked to the vehicle having a software version below 3900 in diagnostic address 5F.

Diagnosis / Trigger Conditions

Technicians will identify the need for this update if the vehicle's diagnostic address 5F reports a software version less than 3900. Additionally, diagnostic entries logged in diagnostic address 0075, related to the emergency call module, will be addressed by this software update. The TSB specifies that Guided Fault Finding test plans for these specific diagnostic entries should not be performed or invoiced, as the software update is the direct remedy.

Repair Procedure Summary

The repair involves performing a software update for the emergency call module (0075) and the information electronics (005F). The process is as follows:

1. Software Update: The technician will use the "SVM – Multiple authorised code inputs" function in "Flash" mode. Specific SVM code chains are provided for different vehicle models (Q3 vs. A4, A5, A6, A7, A8, Q5, Q7, Q8, e-tron GE). These codes must be entered precisely, often by scanning a QR code or copying and pasting.
2. USB Medium: A prepared USB-C stick containing the update software is required. The test program will prompt for its insertion.
3. Automatic Execution: The software update program runs automatically, with acoustic signals and flashing lights indicating when user input is needed.
4. Bus Sleep Mode: After the update, the vehicle must be put into bus sleep mode, then the ignition is switched on, and the MMI is started.
5. Emergency Call LED Check: The emergency call LED in the roof module is checked to ensure it lights up green. If not, further diagnosis using TSB 2079652 is recommended.
6. Diagnostic Session Conclusion: The diagnostic session is ended, and the log is sent.

Required Tools or Parts

To perform this Audi MIB3 MMI software update, specific tools and parts are necessary:

• USB-C Sticks: These must comply with USB 2.0 specifications and have a capacity of 32GB. Larger capacity USB-C sticks are not recommended due to different formatting processes.
• Flash Media Creator (FMC): Used to download the software onto the USB-C stick.
• ODIS Software: The diagnostic tester must have the latest ODIS update to utilize the new test program for SVM code input.

Specific part numbers for the USB update media vary by vehicle model and whether the vehicle is equipped with Sirius radio:

• Audi Q3 without Sirius (I8W with QV0): 8W0.906.961.DJ
• Audi Q3 with Sirius (I8W with QV3): 8W0,906,961,GA
• Audi Q3 without Sirius (I8Y with QV0): 8W0.906.961.DK
• Audi Q3 with Sirius (I8Y with QV3): 8W0.906.961.FT
• Audi A4, A5, Q5 without Sirius (PR number QV0): 8W0.906.961.DK
• Audi A4, A5, Q5 with Sirius (PR number QV3): 8W0.906.961.FT
• Audi A6, A7, Q7, Q8, A8, e-tron without Sirius (PR number QV0): 8W0.906.961.DL
• Audi A6, A7, Q7, Q8, A8, e-tron with Sirius (PR number QV3): 8W0.906.961.FS
