2026 Audi Q8 MMI and Emergency Call Fault TSB 2081197/1

Owners of certain 2026 Audi models may experience problems with various MMI functions or see an "Emergency call fault" message displayed in the instrument cluster. These issues are addressed by Audi Technical Service Bulletin (TSB) 2081197/1, which outlines a software update for the vehicle's infotainment and communication systems.

This TSB specifically targets software-related problems affecting the MIB3 information electronics control unit and the emergency call module/connectivity box. The update aims to restore proper functionality and eliminate the "Emergency call fault" warning.

Symptoms

Owners might notice a range of issues related to the vehicle's infotainment system. The most common symptom is a general malfunction of various MMI functions. Additionally, a critical warning message, "Emergency call fault", may appear in the instrument cluster, indicating a problem with the vehicle's emergency communication system.

Technical Background

According to TSB 2081197/1, the root cause of these issues is identified as software problems within key control units. Specifically, the software update targets Diagnostic address 005F, which is Control unit 1 for information electronics (MIB3), and Diagnostic address 0075, corresponding to the emergency call module control unit and communication unit (connectivity box).

Important Warnings and Owner Information

Audi has provided several crucial advisories regarding this software update:

• Do Not Invoice Guided Fault Finding: The Guided Fault Finding test plans should not be performed or invoiced if the issue is resolved by this TSB.
• Warranty Accounting: Time stamps are not required for billing under warranty when carrying out this TSB. Technicians are permitted to work on other vehicles during the update process.
• Special Test Program: A new test program, "SVM - Authorized Multiple Code Entry", is used for the update. Ensure the diagnostic tester has the latest ODIS software.
• User Input Indicators: The vehicle will use acoustic signals and flashing lights to indicate when user input is required during the "SVM Authorized Multiple Code Entry" test program.
• USB-C Stick Requirement: Prepare the required USB-C sticks before starting the repair. These update media can be used for multiple vehicles.
• Specific SVM Code Entry: The SVM code FLIGHTON0075MLB,ZGDOIP,CL3DA002,TGU1MDMVB,CL3DA001,FLIGHTOFF0075MLB must be entered exactly, including commas and without spaces. Scanning the provided QR code is recommended.
• Interrupted Procedure: If the update procedure is interrupted, repeat step 1. The test program will automatically resume the missing part.
• Bus Sleep Cycle: After the software update, the vehicle must enter a bus sleep mode for at least 30 minutes. Failure to adhere to this duration may lead to functional impairments.
• USB-C Stick Guidelines: Do not use an SD card with an adapter USB stick. Do not use USB-C sticks with larger storage capacity than 32 GB, as they may have different formatting processes. The USB-C stick and the loading of the software cannot be invoiced.
• Out-of-Warranty Vehicles: If the vehicle is outside of any warranty, this Technical Service Bulletin is informational only.
• Emergency Call LED Check: If the emergency call LED in the roof module does not turn green after the update, refer to TSB 2079652, "Emergency call LED in roof module not lit up in green."
