2022-2024 Audi MIB3 MMI Software Update for Emergency Call Fault

Audi has issued Technical Service Bulletin (TSB) 2079133/4 to address various MMI function problems and an 'Emergency call fault' message that may appear in the instrument cluster of certain 2022-2024 MIB3-equipped vehicles. This bulletin outlines a necessary software update to resolve these connectivity and functionality issues.

Symptoms

Owners of affected 2022-2024 Audi vehicles may experience several issues related to the MIB3 infotainment system. These include general problems with various MMI functions, leading to an unsatisfactory user experience. A common specific symptom is the appearance of an "Emergency call fault" message displayed in the instrument cluster.

Workshop findings indicate that vehicles exhibiting these symptoms typically have a software version below 3900 in diagnostic address 5F. This outdated software is the root cause of the MMI malfunctions and the emergency call system errors.

Diagnosis / Trigger Conditions

Diagnosis for this issue primarily involves checking the vehicle's software version. If the vehicle's MIB3 system has a software version less than 3900 in diagnostic address 5F, it is a candidate for this update. The TSB also notes that diagnostic entries logged in diagnostic address 0075 will be resolved by the software update.

It is important to note that standard Guided Fault Finding test plans should not be performed for these specific diagnostic entries, as they will be rectified by the software update itself and cannot be invoiced separately.

Repair Procedure Summary

The repair involves a software update for the emergency call module (0075) and information electronics (005F). This process requires specific tools and adherence to a detailed procedure:

1. Preparation: Prepare the required USB-C sticks with the correct update media. Ensure the diagnostic tester (ODIS) has the latest software version.
2. Software Update Initiation: The technician will use the "SVM – Multiple authorized code inputs" function in "Flash" mode via ODIS. Specific SVM codes must be entered exactly, without spaces. For models like A4, A5, A6, A7, A8, Q5, Q7, Q8, and e-tron (GE), the code is DUCDTCPR0075MLB,FLIGHTON0075MLB,ZGDOIP,CL37A001US,TGU1MDMVB,CL37A002US,FLIGHTOFF0075MLB. For the Q3 model, the code is TGU1MDMVB,CL37A001US,CL37A002US.
3. Media Insertion: Insert the prepared USB-C stick into the vehicle. The update program will then run automatically.
4. Bus Sleep Mode: After the software update completes, the vehicle must be put into bus sleep mode. Following this, the ignition is switched back on, and the MMI is started.
5. Verification: Check if the emergency call LED in the roof module illuminates green. If it does not, refer to TSB 2079652, "91 Emergency call LED in roof module not lit up in green," for further diagnosis.
6. Finalization: End the diagnostic session, remove the USB stick, and disconnect any charging equipment.

During the update, there may be extended inactive periods where the technician can work on other vehicles. Acoustic signals and flashing lights will indicate when user input is required.
