2022-2023 Audi MIB3 MMI Software Update for Emergency Call Fault

Owners of certain 2022-2023 Audi A3, S3, RS 3, e-tron GT, and RS e-tron GT models may experience issues with various MMI functions or see an "Emergency call fault" message displayed in the instrument cluster. These problems are addressed by a critical software update detailed in Audi Technical Service Bulletin (TSB) 2079134/4. This TSB provides instructions for updating the MIB3 infotainment system and associated control units to restore proper functionality and clear the warning messages.

This TSB, identified as 2079134/4, specifically targets software-related issues within the MIB3 system and the connectivity box. The update ensures that the vehicle's communication and infotainment systems operate as intended, preventing further disruptions and ensuring the emergency call function is fully operational. This Audi MIB3 MMI software update is crucial for maintaining the vehicle's safety features and user experience.

Revision History

Audi has updated this Technical Service Bulletin multiple times to refine the repair process and information:

• Revision 4: The header was revised for improved visibility.
• Revision 3 (December 16, 2026): The condition section was revised to include an updated model table.
• Revision 2 (October 7, 2025): The service section was revised, specifically updating the QR code and SVM code information.
• Revision 1: The warranty section was revised to update labor operations.

Symptoms

Owners may notice one or both of the following issues, indicating a need for the Audi MIB3 MMI software update:

• Problems with various MMI functions: This can manifest as erratic behavior, freezing, or unresponsiveness of the Multi Media Interface (MMI) system, affecting navigation, audio, or other integrated features.
• "Emergency call fault" displayed in the instrument cluster: This warning indicates a malfunction with the vehicle's emergency call system, which is a critical safety feature designed to automatically contact emergency services in the event of a crash.

Diagnosis and Trigger Conditions

Workshop findings indicate that affected vehicles typically have a software version below 3900 in diagnostic address 5F, which is associated with the infotainment system. The presence of this older software version is a key indicator that the software update is required. Diagnostic entries logged in diagnostic address 0075, related to the emergency call module, are also addressed and repaired by this software update. Additionally, issues related to information electronics (diagnostic address 005F) and volume control (diagnostic address 0693) are covered by this TSB.

Important Warnings and Owner Information

Audi has provided several crucial advisories regarding this software update. Owners and technicians should pay close attention to these points to ensure a successful repair and avoid unnecessary costs:

• Do not carry out Guided Fault Finding test plans: For diagnostic entries logged in diagnostic address 0075, the Guided Fault Finding test plans should not be carried out and cannot be invoiced. The software update itself will resolve these entries.
• Expect inactive time during update: A lengthy period of inactive time is to be expected during the software update. Technicians are permitted to work on other vehicles during this time, and this is considered in the warranty accounting instructions. Owners should be aware of the potential duration for the service.
• No time stamps for warranty billing: When carrying out this TSB, time stamps are not required for billing under warranty.
• New test program and ODIS update required: A newly developed test program is used to input the SVM code. Technicians must ensure that the tester being used has the latest ODIS update, which includes this new test program for software updates.
• Vehicle communication during update: The vehicle uses acoustic signals and flashing lights to indicate when user input is required during and at the end of the test program.
• Required USB-C sticks: Please prepare the 2 required USB-C sticks (as detailed in the parts information) before starting the repair. The update media can be used for multiple vehicles.
• Related TSB for MIB3 information: This update package also includes new software for the MIB3 infotainment system. Useful information for MIB3 software updates can be found in TSB 2060523: 91 MIB3: Software Update Instructions.
• Do not use SD cards: You must not use an SD card with an adapter USB stick for this procedure.
• USB-C stick storage capacity: Please do not use a USB-C stick with a larger storage capacity as such USB sticks have a a different formatting process. USB-C sticks must comply with the USB 2.0 specification and have a 32GB capacity.
• Interrupted procedure: If the procedure has been interrupted, please repeat step 2 of the repair. The test program will then automatically perform the missing part of the update.
• Emergency Call LED check: If the emergency call LED in the roof module does not turn green after the update, please refer to TSB 2079652, 91 Emergency call LED in roof module not lit up in green, for further diagnosis.

Repair Procedure Summary

The repair involves a two-part software update process, ensuring the comprehensive resolution of the MMI and emergency call system issues. This Audi MIB3 MMI software update requires specific tools and careful execution by a qualified technician.

Step 1: Manual Software Update of Volume Control (Diagnostic Address 0693) via Red Menu

This initial update focuses on the volume control module and is performed through the MMI's hidden red menu. The technician will follow these steps:

1. Prepare USB Medium: Insert a prepared USB update medium into the vehicle's USB connection. The specific part number for the USB medium depends on the current software version of the volume control module (diagnostic address 0693).
2. Access Red Menu: Access the red menu in the MMI. The TSB includes an image illustrating this, showing a hand pressing a button on the MMI screen, with other buttons labeled 'RADIO', 'MEDIA', 'NAV', 'TEL', 'CAR', 'SETUP' visible, indicating how to access this diagnostic menu.
3. Select Update Source: Select the "Update" option and choose the USB connection as the source, using the volume control knob.
4. Initiate Update: Review all control units slated for update, scroll down the list, and initiate the update process.
5. Complete Manual Update: Once the manual update is successfully completed, the technician must leave the red menu entirely before starting a diagnostic session.

Step 2: SVM Code Update for Emergency Call Module (Diagnostic Address 0075) and Information Electronics (Diagnostic Address 005F)

This step utilizes the SVM (Software Version Management) system to update critical modules, including the emergency call module and information electronics. The technician will:

1. Use SVM Function: Access the "SVM – Multiple authorized code inputs" function in "Flash" mode using the diagnostic tester.
2. Enter SVM Code: Carefully enter the specific SVM code chain. The TSB strongly recommends scanning the provided QR code with a hand-held scanner or copying and pasting the code to ensure accuracy, as it must be entered exactly, including commas and without spaces.
   • For e-tron GT vehicle models, the SVM code is: 693A001,DUCDTCPR0075MLB,FLIGHTON0075MLB,ZGDOIP,CL37A001US,TGU1MDMVB,CL37A002US,FLIGHTOFF0075MLB
   • For A3 vehicle models, the SVM code is: 693A001,TGU1MDMVB,ZGDOIP,CL37A001US,CL37A002US
3. USB Medium Prompt: The test program will initially prompt for the USB medium. The USB-C stick can be removed after the program is complete.
4. Interruption Handling: If the procedure is interrupted, step 2 must be repeated, and the test program will automatically perform the missing part of the update.

Post-Update Procedures

After both software updates are complete, the following steps are necessary to finalize the repair and verify functionality:

1. Bus Sleep Mode: Put the vehicle into bus sleep mode after performing the software update. Then, switch the ignition back on and start the MMI.
2. Emergency Call LED Check: Check whether the emergency call LED in the roof module lights up in green again. If the LED does not turn green, further diagnosis is required, referring to TSB 2079652: 91 Emergency call LED in roof module not lit up in green.
3. End Diagnostic Session: Conclude the diagnostic session and send the diagnostic log to GFF paperless.
