2024-2025 Audi e-tron GT MMI Software Update TSB 2079980/3

Audi has issued Technical Service Bulletin (TSB) 2079980/3 to address various MMI function problems and an "Emergency call fault" message that may appear in the instrument cluster of certain 2024-2025 Audi e-tron GT and RS e-tron GT vehicles. This TSB outlines a comprehensive software update procedure for the MIB3 infotainment system and related control units.

This TSB, identified as 2079980/3, was most recently revised on March 27, 2026. Previous revisions include Revision 2 on December 4, 2025, which updated the service and SVM code, and Revision 1 on November 17, 2025, for initial publication.

Symptoms

Owners may experience general problems with various MMI functions. Additionally, the instrument cluster might display an explicit "Emergency call fault" message, indicating an issue with the vehicle's emergency call system.

Affected Software Versions

This Audi e-tron GT MMI software update is applicable to vehicles that currently have one of the following software versions in diagnostic address 5F (MMI control unit): 4014, 4026, 4318, or 4404. The new software for the affected control units was implemented in production for model year 2025, meaning later models should not exhibit these issues.

Important Warnings for Owners

• Do not replace parts unnecessarily: Diagnostic entries logged in diagnostic address 0075 will be resolved by the software update. Guided Fault Finding test plans for these entries should not be carried out and cannot be invoiced.
• Prepare for downtime: A lengthy period of inactive time is expected during the software update. While technicians can work on other vehicles during this time, your vehicle will be unavailable.
• Specific software version check: The update for the Android control unit (diagnostic address 078E) must only be performed if its software version is below 0621.
• USB stick handling: You must prepare two specific USB-C sticks before starting the repair. It is crucial to "Please be certain to leave the USB stick inserted" during the update process until instructed otherwise. The procedure will only work if the USB stick remains inserted. Do not use an SD card with an adapter USB stick, and avoid USB-C sticks with larger storage capacities as they may have different formatting processes.
• No consumer notification: Audi is not notifying consumers directly about this TSB. Owners must proactively address the Audi e-tron GT MMI software update.
• Warranty considerations: If your vehicle is outside of its warranty period, this Technical Service Bulletin is for informational purposes only, and repair costs may apply.

Repair Procedure Summary

The repair involves a manual software update for the AED control unit (078E) and the MIB3 infotainment system. This process requires specific USB-C media and the use of the ODIS diagnostic system.

1. Prepare Update Media: Two USB-C sticks are required. Download the appropriate software onto these sticks. General information on MIB3 software updates can be found in TSB 2060523, titled "91 MIB3: Software Update Instructions."
2. Manual AED Control Unit Update: If the Android control unit (078E) software version is below 0621, insert the USB update medium into the USB connection. Access the red menu in the MMI by pressing specific buttons, then select "Update" and the correct source. All control units to be updated (AED) will be displayed. Start the update.
3. System Restart and Verification: After the manual update, exit the red menu. The MMI will restart. Wait for full initialization and for the home screen to display all apps. Restart the system again by pressing and holding the volume control for 10 seconds. Check the notification center under "Audi connect notifications" for messages like "OTA Updater Service" or "Software Update". Wait for messages such as "Download des Software Update beendet" and "Gratulation! Software 0621 wurde erfolgreich installiert."
4. Remove USB Stick: Once the download is complete and the system confirms successful installation, you can remove the USB stick.
5. SVM Code Entry: For the AED control unit, emergency call module (0075), gateway (0019), and information electronics (005F), an SVM (Software Version Management) code must be entered using the "SVM - Authorized Multiple Code Entry" function in ODIS "Flash" mode. The SVM code chain, such as DUCDTCPR0075MLB and FLIGHTON0075MLB, must be entered exactly as provided, often via QR code scan.
   • For gateway software version 0019 = 0042, use SVM code chain: 078EA001,DUCDTCPR0075MLB, FLIGHTON0075MLB, ZGDOIP, CL3BPA001US, 19A027, 19B027,TGU1MDMVB,CL3BPA002US, FLIGHTOFF0075MLB.
   • For all other software versions in diagnostic address 0019, use SVM code chain: 078EA001,DUCDTCPR0075MLB, FLIGHTON0075MLB, ZGDOIP, CL3BPA001US, TGU1MDMVB, CL3BPA002US, FLIGHTOFF0075MLB.
6. Bus Sleep Mode: After the software update, put the vehicle into bus sleep mode. Then, switch the ignition back on and start the MMI.
7. Emergency Call LED Check: Verify that the emergency call LED in the roof module illuminates green again. If it does not, refer to TSB 2079652, "Emergency call LED in roof module not lit up in green."
8. End Diagnostic Session: Conclude the diagnostic session and send the diagnostic log online.
