2022-2024 Audi MMI Software Update for Connectivity Box

Owners of 2022-2024 Audi vehicles may experience issues with their Multi Media Interface (MMI) system or receive an "Emergency call fault" message. These problems, including the display of "Connection offline", are addressed by a software update outlined in Technical Service Bulletin (TSB) 2079133/4. This update targets the connectivity box for MIB3 vehicles, specifically those with NAR version ST37 software.

This Audi MMI software update is crucial for maintaining the full functionality of your vehicle's infotainment and safety systems. The TSB, released on February 6, 2026, provides comprehensive instructions for dealerships to perform the necessary software upgrade.

Revision History

This Technical Service Bulletin has undergone several revisions to ensure accuracy and completeness:

• Revision 4: The header was updated for improved visibility.
• Revision 3 (December 16, 2026): The header was revised, model years were added, the 'Condition' section was updated with a model table, and the 'Service' section was revised to include updated QR codes and SV codes.
• Revision 2 (October 7, 2025): The header was revised to include additional models, and the 'Warranty' table was updated.

Symptoms

Owners may notice several issues indicating the need for this software update. The most common complaints include problems with various MMI functions, which can manifest in different ways, such as unresponsive controls or incorrect displays. A critical symptom is the display of an "Emergency call fault" message in the instrument cluster, indicating a potential issue with the vehicle's emergency communication system. Additionally, the message "Connection offline" may appear, signaling a loss of connectivity for the MMI system.

Diagnosis

For technicians, the primary diagnostic finding for these issues is a vehicle still operating with a software version below 3900 in diagnostic address 5F. This indicates that the MIB3 infotainment system requires the latest software package. The TSB also notes that diagnostic entries logged in diagnostic address 0075, related to the emergency call module, will be repaired by this software update.

Important Warnings and Information for Owners

Audi has provided several important advisories regarding this TSB 2079133/4 and the software update process:

• Do Not Invoice Guided Fault Finding: Diagnostic entries logged in diagnostic address 0075 will be repaired by this software update. Therefore, Guided Fault Finding test plans related to these entries should not be carried out and cannot be invoiced.
• Extended Inactive Periods: The software update procedure will involve extended inactive periods for some steps. Technicians can work on other vehicles during this time, and this is accounted for in warranty billing.
• No Time Stamps Required: When performing this TSB, time stamps are not required for billing under warranty.
• Specialized Test Program: A new test program is used to input the SVM code. Dealerships must ensure their diagnostic tester has the latest ODIS update, which includes this new test program.
• Acoustic and Visual Cues: 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 Preparation: It is important to prepare the required USB-C sticks (as detailed in the parts information section) before starting the repair. The update media can be used for multiple vehicles.
• MIB3 Infotainment System: This update package also includes new software for the MIB3 infotainment system. Further information on MIB3 software updates can be found in TSB 2060523, titled "91 MIB3: Software Update Instructions."
• Interrupted Procedure: If the procedure has been interrupted, please repeat step 1. The test program will then automatically perform the missing part of the update.

Repair Procedure Summary

The repair involves a multi-step software update process for the emergency call module (0075) and information electronics (005F). This Audi MMI software update is performed using specific tools and software, ensuring the MIB3 system is brought up to date.

1. Software Update for Emergency Call Module (0075) and Information Electronics (005F):

   • Technicians must use the function "SVM – Multiple authorized code inputs" in "Flash" mode within the ODIS system.
   • For the new software update program, a specific SVM code chain must be entered exactly, including commas and without spaces. It is recommended to scan the provided QR code with a hand-held scanner or copy and paste the SVM code chain to avoid errors.
   • For Audi A4, A5, A6, A7, A8, Q5, Q7, Q8, and e-tron (GE) models, the SVM code chain is: DUCDTCPR0075MLB,FLIGHTON0075MLB,ZGDOIP,CL37A001US,TGU1MDMVB,CL37A002US,FLIGHTOFF0075MLB.
   • For the Audi Q3 model, the SVM code chain is: TGU1MDMVB,CL37A001US,CL37A002US.
   • The test program will initially prompt the technician to use a USB medium. The automatic execution of software updates will result in inactive time, which is accounted for in warranty instructions.

2. Bus Sleep Mode:

   • After the software update is completed, the vehicle must be put into bus sleep mode. This involves switching the ignition off and allowing the vehicle to enter a low-power state.
   • Then, the ignition should be switched back on, and the MMI system started.

3. Check Emergency Call LED:

   • The technician must verify that the emergency call LED in the roof module illuminates green. This indicates proper function of the emergency call system.
   • If the LED does not turn green, further diagnosis is required, referring to TSB 2079652, titled "91 Emergency call LED in roof module not lit up in green."

4. End Diagnostic Session:

   • Finally, the diagnostic session should be ended, and the diagnostic log sent to GFF paperless for documentation.

Required Tools or Parts

To perform this Audi MMI software update, specific USB-C sticks are required to create the update media. Technicians must prepare these sticks before starting the repair. It is important to note that you must not use an SD card with an adapter USB stick. The software must be downloaded onto a USB-C stick that complies with the USB 2.0 specification and has a capacity of 32GB using the Flash Media Creator (FMC). Please do not use a USB-C stick with a larger storage capacity as such USB sticks have a different formatting process.
