Diagnostic Addresses and Software Versions

While no traditional DTC (Diagnostic Trouble Code) is explicitly listed in a P-code format, the bulletin references specific diagnostic addresses where software versions are checked and updates are applied. These include:

• 005F - Information electronics: Vehicles with a software version below 3900 (<3900) in this diagnostic address are candidates for the update. The document notes examples of software versions 38* and 36* for this address.
• 0075 - Emergency call module: Diagnostic entries in this module will be repaired by the software update.
• 0693 - Volume control: This module also receives a software update, requiring a second USB-C stick for the process.

Diagnosis and Technical Background

The primary diagnostic finding is that the vehicle's information electronics (diagnostic address 005F) still have a software version below 3900. If a technician encounters various MMI functionality problems or an "Emergency call fault" display, checking this software version is the initial step. The technical background indicates that these issues are primarily due to software problems within the MIB3 system. The new software for the affected control units was implemented in production starting with model year 2025 vehicles.

Important Warnings for Owners

Owners and technicians should be aware of several critical points regarding this TSB 2079134/2:

• Future Release Date: This Technical Service Bulletin is noted with a release date of October 7, 2025. Owners should be aware of this future date when seeking this specific update.
• Invoicing Restrictions: Guided Fault Finding test plans should not be carried out for diagnostic entries that are repaired by performing this TSB and cannot be invoiced.
• Warranty Billing: When carrying out this TSB, time stamps are not required for billing under warranty. This allows technicians to work on other vehicles concurrently, and the update can be performed by non-productive personnel.
• User Input Indicators: The vehicle uses acoustic signals and flashing lights to indicate when user input is required during and at the end of the test program.
• USB Media Restrictions: Do not use an SD card with an adapter USB stick for the update process. Also, do not use a USB-C stick with a larger storage capacity than specified (32GB) as such USB sticks have a different formatting process.
• Non-Invoicable Items: The USB-C stick itself and the process of downloading the software via the Flash Media Creator (FMC) cannot be invoiced.
• Interrupted Procedure: If the update procedure is interrupted, repeat step 2. The test program will then automatically perform the missing part of the update.
• Emergency Call LED: If, after the update, the emergency call LED in the roof module does not turn green, technicians must refer to TSB 2079652, titled "91 Emergency call LED in roof module not lit up in green."
• Out-of-Warranty Vehicles: If the vehicle is outside of any warranty, this Technical Service Bulletin is informational only, meaning the repair may not be covered.

Detailed Repair Procedure

The repair involves a multi-step software update process for the MIB3 system, connectivity box, and associated control units. This process requires specialized tools and careful execution:

Step 1: Preparation

Before beginning the update, ensure the vehicle is parked and the 12V battery is charged. Two USB-C sticks are required for the update process. General information on preparing USB-C sticks and MIB3 software updates can be found in TSB 2060523, "91 MIB3: Software Update Instructions."

Step 2: Manual Software Update of Volume Control (0693) via Red Menu

This initial update is performed through the MMI's red menu. Insert the USB update medium into the USB connection. Select the red menu by pressing the appropriate buttons on the MMI system. The image shows a hand interacting with the Audi MMI touchscreen, illustrating the process of selecting 'Update' from the menu. Then, select "Update" and choose the source where the USB update medium is inserted. Use the volume control to navigate and initiate the update. All control units designated for update will be displayed. Scroll down and start the update. Once this manual update is successfully completed, exit the red menu entirely before proceeding to a diagnostic session.

Step 3: SVM Code Entry for Control Modules

This step involves using the "SVM – Multiple authorized code inputs" function in "Flash" mode with an ODIS tester that has the latest updates. A newly developed test program is used to input the SVM code. The specific SVM code chain must be entered exactly, including commas and without spaces. It is recommended to scan a QR code with a hand-held scanner or copy and paste the code chain to prevent errors.

• For e-tron GT models, the SVM code is: 693A001,FLIGHTON0075MLB,ZGDOIP,CL37A001US,TGU1MDMVB,CL37A002US,FLIGHTOFF0075MLB
• For A3 vehicle models, the SVM code is: 693A001,TGU1MDMVB,ZGDOIP,CL37A001US,CL37A002US

If the procedure is interrupted during this step, repeat the step, and the test program will automatically complete the missing part of the update.

Step 4: Bus Sleep Mode and MMI Restart

After the software update is complete, the vehicle must be put into bus sleep mode. Following this, switch the ignition back on and start the MMI system.

Step 5: Emergency Call LED Check

After the MMI has restarted, check if the emergency call LED in the roof module lights up green. If it does not, further diagnosis is required by referring to TSB 2079652, "91 Emergency call LED in roof module not lit up in green."

Step 6: Conclude Diagnostic Session

Finally, end the diagnostic session and send the diagnostic log to GFF paperless.

Required Tools and Parts

Performing this software update requires specific media and tools.

USB-C Stick Requirements

Two USB-C sticks are required for the update process. These must comply with USB 2.0 specifications and have a capacity of 32GB. SD cards with adapter USB sticks are explicitly not to be used, nor are USB-C sticks with larger storage capacities due to different formatting processes.

Software Download Tools

• Flash Media Creator (FMC): Used for downloading the software onto the USB-C sticks.
• ODIS Tester: Must have the latest updates installed to run the new test program for SVM code input.
