2024-2025 Audi MMI Emergency Call Fault Software Update TSB

Audi has released Technical Service Bulletin (TSB) 2081007/1, dated February 17, 2026, to address potential software-related issues affecting the Multi Media Interface (MMI), Online Connectivity Unit (OCU), and gateway modules in certain 2024-2025 Audi A3, S3, RS 3, and Q3 vehicles. This TSB outlines a software update designed to resolve problems with various MMI functions and the appearance of an "Emergency call fault" message in the instrument cluster. If you are experiencing a 2024 Audi S3 MMI Emergency Call Fault, this bulletin provides the necessary information for its resolution.

Symptoms

Owners of affected Audi models may notice problems with various MMI functions, which can impact navigation, entertainment, and other integrated vehicle systems. A key indicator of this issue is the display of an "Emergency call fault" message within the instrument cluster. These symptoms are specifically linked to vehicles still operating with certain software versions in diagnostic address 5F, including 4140, 4142, 4143, 4318, or 4364.

Technical Background

The root cause of these MMI and emergency call system issues has been identified as software-related. The TSB specifies that vehicles still exhibiting any of the software versions 4140, 4142, 4143, 4318, or 4364 in diagnostic address 5F are susceptible to these problems. The new software, which was implemented in production vehicles starting in model year 2026, aims to rectify these underlying software discrepancies. This TSB may also be referenced by other bulletins in the context of a broader software update for multiple control units.

Important Warnings and Information for Owners

Audi has provided several critical advisories for technicians, which also contain important information for owners:

• Diagnostic Entries: Diagnostic entries logged in diagnostic address 0075 will be repaired by the software update described in this TSB. Technicians are instructed that Guided Fault Finding test plans related to these entries should not be carried out and cannot be invoiced, as the update itself is the corrective action.
• Service Time: The software update procedure involves extended inactive periods. While technicians may work on other vehicles during these times, owners should be aware that the process is not instantaneous.
• Warranty Billing: When this TSB is performed, time stamps are not required for billing under warranty. This allows for more flexible scheduling of the update.
• USB-C Sticks: The repair requires specific USB-C sticks to load the update media. Technicians are explicitly warned to not use an SD card with an adapter USB stick. Furthermore, USB-C sticks with a larger storage capacity should not be used due to different formatting processes.
• Invoicing Restrictions: The cost of the USB-C stick and the time spent loading the software onto it cannot be invoiced.
• Procedure Interruption: If the software update procedure is interrupted for any reason, technicians must repeat step 1. The test program is designed to automatically resume the missing part of the update.
• SVM Code Entry: The SVM code, which authorizes the software update, must be entered exactly as provided, including commas and without spaces. Copying and pasting or scanning a QR code is recommended to prevent errors.

Affected Software Versions

The issues described in TSB 2081007/1 are linked to specific software versions found in diagnostic address 5F. Vehicles with any of the following software versions are affected:

• 4140
• 4142
• 4143
• 4318
• 4364

These versions are found in 2024-2025 Audi A3, S3, RS 3, and Q3 models, with specific configurations related to PR Codes UI4 and B30, and certain VIN ranges.

Detailed Repair Procedure

The repair involves a comprehensive software update for the emergency call module (0075), gateway (0019), and information electronics (005F) using the "SVM - Authorized Multiple Code Entry" function in "Flash" mode. The procedure is as follows:

1. Initial Preparation: The vehicle must be parked, and the 12V battery charged to ensure stable power throughout the update process. Technicians will connect a diagnostic tester and start the ODIS software, ensuring it has the latest updates.
2. Launch Software Update: The software update for the MMI and emergency call module is initiated. This involves selecting the "SVM - Authorized Multiple Code Entry" function in "Flash" mode. Technicians will then copy and paste the specific SVM code chain (often provided via QR code for accuracy) and insert the prepared USB-C stick into the vehicle's port. 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.
   • For A3 vehicle models, the SVM code is: ZGDOIP,CL3BPA001US,TGU1MDMVB,CL3BPA002US
   • For Q3 vehicle models, the SVM code is: CL3BPA002US
3. Automatic Program Execution: Once initiated, the update program runs automatically. During this phase, the service technician is not required to actively monitor the process, allowing for work on other vehicles. The automatic execution of software updates results in inactive time for the vehicle.
4. Procedure Interruption Handling: If the software update procedure is interrupted for any reason, technicians are instructed to repeat step 1. The test program is designed to automatically perform only the missing part of the update upon restart.
5. Conclude Software Update: After the program completes, the current test program is ended, and the USB-C stick can be safely removed from the vehicle.
6. Bus Sleep Mode Activation: The vehicle is then put into bus sleep mode. Following this, the ignition is switched back on, and the MMI system is restarted.
7. Emergency Call LED Verification: Technicians must check whether the emergency call LED in the roof module lights up in green again. If the LED does not turn green, further diagnosis is required by referring to TSB 2079652, titled "Emergency call LED in roof module not lit up in green."
8. Finalization: The diagnostic session is ended, and the diagnostic log is sent online. Finally, the charger is disconnected from the vehicle.

This procedure ensures that the 2024 Audi S3 MMI Emergency Call Fault and other related MMI issues are thoroughly addressed.

Required Tools and Parts

To perform this software update, technicians will need specific items:

• USB-C Sticks: These are essential for creating the update media. Audi specifies that a minimum of USB 2.0 with 32 GB capacity is required. It's crucial to use the correct type and size of USB-C stick, as larger capacities may have different formatting processes. General information regarding USB-C sticks for software updates can be found in TSB 2060523, titled "91 MIB3: Software Update Instructions."
• MIB3 Update Media Part Numbers: The software itself is downloaded using specific part numbers:
  • For MIB3 Basic (PR code I8W): 8W0906961GH
  • For MIB3 High (PR code I8Y): 8W0906961GG
