2024-2025 Audi MIB3 Software Update for MMI & Emergency Call Fault

The Audi Technical Service Bulletin (TSB) 2079671/3, released on November 19, 2025, addresses concerns regarding various MMI functions and the display of an "Emergency call fault" message in certain 2024-2025 Audi A4, A5, Q5, S4, S5, SQ5, and RS 5 models. This TSB outlines a crucial software update for the MIB3 infotainment system and associated control units, including the connectivity box (MLB G1 ST3BP with AED). Owners experiencing an Audi MMI emergency call fault or other MMI performance issues should be aware of this service action.

This bulletin, identified as Transaction No.: 2079671/3, provides detailed instructions for technicians to update the software in the affected control units, ensuring proper functionality of the MMI system and the emergency call feature. The update specifically targets vehicles with older software versions that may be causing these problems. The TSB has undergone several revisions, with Revision 1 published on October 14, 2025, and Revision 3 updating the header and SW filter.

Symptoms and Affected Software Versions

Owners may observe problems with various MMI functions or see an "Emergency call fault" message displayed in the instrument cluster. These symptoms are typically linked to specific software versions within the vehicle's diagnostic address 5F.

The TSB identifies the following software versions as potentially problematic:

• 4014
• 4026
• 4318
• 4404

Vehicles equipped with MIB3 systems, particularly those with the AED (Audi Entertainment Device) and Android control unit (078E) running software version below 0621, are the primary focus of this update. The software update also addresses diagnostic entries logged in diagnostic address 0075, which will be repaired by performing the update described in TSB 2079671/3.

Important Warnings and Owner Information

Audi has provided several critical advisories for this software update:

• Guided Fault Finding: "The Guided Fault Finding test plans should not be carried out and cannot be invoiced" for diagnostic entries that are repaired by this software update.
• Update Duration: "A lengthy period of inactive time is to be expected during the software update. You can work on a different vehicle during this time." This is considered in the warranty accounting instructions.
• Warranty Billing: "When carrying out this TSB, time stamps are not required for billing under warranty." This indicates flexibility for dealerships in managing their time during the update process.
• ODIS Update: Technicians must ensure their ODIS diagnostic system has the latest update, as a newly developed test program is used for inputting the SVM code. The new test program for software updates is included in ODIS software.
• User Input Indicators: The vehicle will use "acoustic signals and flashing lights to indicate when user input is required during and at the end of the test program."
• USB-C Stick Requirement: A second USB-C stick is necessary for the software update for the Android control unit. This update must only be performed if the software version in diagnostic address 078E is below 0621.
• Preparation: "Please prepare the required USB-C sticks" before starting the repair. The update media can be used for multiple vehicles.
• Related TSBs: This update package also includes new software for the MIB3 infotainment system. Useful information for MIB3 software updates can be found in TSB 2060523, titled "91 MIB3: Software Update Instructions."
• USB Stick Management: During the manual update, technicians are explicitly warned: "Please make absolutely sure to leave the USB stick inserted. The correct time to remove the USB stick is described further down." The procedure "will only work if the USB stick is still inserted" during certain steps. The instruction "Now please remove the USB stick" is given at a specific point.

Repair Procedure Summary

The repair involves a two-part software update process to address the Audi MMI emergency call fault and other related issues. This procedure is detailed in Audi TSB 2079671/3.

1. Manual Software Update for AED Control Unit (078E) via Red Menu

This step is performed if the Android control unit (078E) has a software version below 0621. The update is done through the MMI's hidden "red menu."

• Preparation: Insert the USB update medium into the USB connection.
• Access Red Menu: Select the red menu by pressing the following buttons: RADIO, MEDIA, NAV, TEL, CAR, TONE, MENU.
• Initiate Update: Navigate to "Update" and select the USB connection as the source. All control units designated for update, including the AED, will be displayed. Scroll down and start the update.
• Post-Update Steps: After the manual update completes, exit the red menu entirely before starting a diagnostic session.
• USB Stick Management: It is critical to keep the USB stick inserted until explicitly instructed to remove it. The MMI will restart and initialize. "Please wait" during this process. The procedure "will only work if the USB stick is still inserted" during certain steps. The instruction "Now please remove the USB stick" is given at a specific point.
• System Restart: Restart the MMI system by pressing and holding the volume control for 10 seconds.
• Verification: Open the notification center and switch to the "Audi connect notifications" tab. Wait for several minutes for information to appear, as the download takes approximately 5 minutes.
• Confirmation: Verify the update's success by checking the notification center or Audi connect notifications.

2. SVM Code Update for Emergency Call Module (0075), Gateway (0019), and Information Electronics (005F)

This step uses the SVM (Software Version Management) system to update the emergency call module (0075), gateway (0019), and information electronics (005F).

• SVM Function: Use the "SVM - Multiple authorized code inputs" function in "Flash" mode.
• Exact Code Entry: It is crucial to enter the SVM code chain exactly as provided, including commas and without spaces. Scanning the QR code with a hand-held scanner or copying and pasting is recommended. "IMPORTANT: For the new software update program, the following SVM code must be entered exactly, including commas and without spaces."
• Hardware Version Determination: Determine the hardware version of the gateway (diagnostic address 0019) using the SVM code DUCIDENT0019.
• Specific SVM Codes:
  • For gateway hardware version H08, use the SVM code: DUCIDENT0019,078EA001,FLIGHTON0075MLB,ZGDOIP,CL3BPA001US,TGU1MDMVB,CL3BPA002US,FLIGHTOFF0075MLB
  • For all other gateway hardware versions (e.g., H06), use the SVM code: DUCIDENT0019,078EA001,FLIGHTON0075MLB,ZGDOIP,CL3BPA001US,19A027,19B027,TGU1MDMVB,CL3BPA002US,FLIGHTOFF0075MLB
• Post-Update: The test program may prompt for a USB medium initially, but the USB-C stick can be removed after completing the program.

Final Steps

• Bus Sleep Mode: After the software update, the vehicle must be put into bus sleep mode.
• Emergency Call LED Check: Verify that the emergency call LED in the roof module lights up green. If it does not, refer to TSB 2079652 for further diagnosis.
• Diagnostic Session: End the diagnostic session and send the diagnostic log online.

Required Tools and Parts

To perform the software update described in TSB 2079671/3, technicians will need the following:

• USB-C Sticks: Required for the update process. It is important not to use an SD card with an adapter USB stick or a USB-C stick with larger storage capacity, as these may have different formatting processes. General information on USB-C sticks for software updates can also be found in TSB 2060523, "91 MIB3: Software Update Instructions."
• ODIS Diagnostic System: Must be updated to the latest version to utilize the newly developed test program for SVM code input.
• AED Control Unit Update Media: Part number 8W0906961DQ.
• MIB3 Update Media (Software Versions 4014, 4026, 4404): Part number 8W0906961GC.
• MIB3 Update Media (Software Version 4318): Part number 8W0906961GG.
