2024-2025 Audi MMI and Emergency Call System Software Update

Owners of certain 2024-2025 Audi A4, A5, and Q5 models may experience problems with various MMI functions or see an "Emergency call fault" message displayed in the instrument cluster. Audi has issued Technical Service Bulletin (TSB) 2079813/2 to provide a software update solution for these issues, specifically targeting the MMI connectivity box for MIB3 vehicles.

This TSB, identified as 2079813/2, was most recently revised on November 17, 2025, superseding an earlier version dated October 22, 2025. It details a comprehensive software update designed to resolve the underlying software-related problems that can lead to the Audi MMI emergency call fault and other MMI irregularities.

Symptoms

Owners may notice a range of issues related to their vehicle's MMI system. The most prominent symptom is the display of an "Emergency call fault" message within the instrument cluster. Beyond this specific warning, various other MMI functions might exhibit problematic behavior, indicating a general software instability or malfunction. If you encounter an Audi MMI emergency call fault or other MMI problems, this TSB likely applies to your vehicle.

Affected Software Versions and Modules

This software update specifically targets vehicles that currently have one of the following software versions in diagnostic address 5F: 4014, 4026, 4318, or 4404. The update applies to the emergency call module (0075) and the information electronics (005F), which are critical components for both communication and infotainment functionalities in MIB3-equipped Audi vehicles.

Diagnosis and Trigger Conditions

Technicians will diagnose the issue by checking the current software version present in diagnostic address 5F. If the vehicle is found to have software version 4014, 4026, 4318, or 4404, it is a candidate for this software update. The problems are rooted in software issues, and the new software version has already been implemented in production for newer vehicles, indicating that the existing software versions are the root cause for the Audi MMI emergency call fault and other MMI issues.

Repair Procedure Summary

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

1. Preparation: The vehicle must be parked, and the 12V battery charged. Technicians connect a tester and start ODIS (Offboard Diagnostic Information System).
2. Software Update Initiation: The function "SVM - Authorized Multiple Code Entry" is used in "Flash" mode. An SVM code chain, FLIGHTON0075MLB,ZGDOIP,CL3BPA001US,TGU1MDMVB,CL3BPA002US,FLIGHTOFF0075MLB, must be entered exactly. Audi recommends scanning a QR code or copying and pasting this code to avoid errors.
3. Media Insertion: A prepared USB-C stick containing the new software is inserted into the vehicle.
4. Automatic Update: The program runs automatically, and the software update proceeds. This process may involve inactive periods, during which technicians can work on other vehicles.
5. Completion and Bus Sleep Mode: Once the program concludes, the USB-C stick is removed. The vehicle is then put into bus sleep mode, after which the ignition is switched off and on again, and the MMI is restarted.
6. Verification: The emergency call LED in the roof module is checked to ensure it lights up green. If it does not, technicians are instructed to refer to TSB 2079652 for further guidance.
7. Finalization: The diagnostic session is ended, and the diagnostic log is sent online.

Required Parts and Tools

To perform this software update, specific tools and media are required:

• USB-C Sticks: Technicians must prepare required USB-C sticks with a minimum capacity of 32 GB and USB 2.0 compatibility. It is crucial not to use SD cards with adapter USB sticks or USB-C sticks with larger storage capacities, as these may have different formatting processes.
• ODIS Update: The tester used for the update must have the latest ODIS software.
• Software Part Numbers: The specific software to be downloaded onto the USB-C stick depends on the vehicle's current MIB3 software version:
  • For MIB3 SW versions 4014, 4026, 4404: Part number 8W0906961GC
  • For MIB3 SW version 4318: Part number 8W0906961GG

Additional information regarding MIB3 software updates and USB-C sticks can be found in TSB 2060523, titled "91 MIB3: Software Update Instructions."

Important Warnings and What Owners Should Know

• Diagnostic Entries: Diagnostic entries logged in diagnostic address 0075 will be resolved by this software update. Guided Fault Finding test plans related to these entries should not be carried out and cannot be invoiced.
• Warranty Billing: When carrying out this TSB, time stamps are not required for billing under warranty. Furthermore, the USB-C stick and the software download via the FMC cannot be invoiced.
• USB-C Stick Usage: It is critical to prepare the required USB-C sticks. Do not use an SD card with an adapter USB stick, and do not use a USB-C stick with a larger storage capacity as these may have different formatting processes.
• Interrupted Procedure: If the software update procedure is interrupted, technicians must repeat step 1, and the test program will automatically complete the missing part of the update.
• Emergency Call LED: If, after the update, the emergency call LED in the roof module does not light up green, refer to TSB 2079652, "Emergency call LED in roof module not lit up in green," for further diagnosis.
