2026 Audi MMI and Emergency Call Software Update TSB

Owners of certain 2026 Audi models may experience issues with various MMI functions or see an "Emergency call fault" message displayed in the instrument cluster. Audi has released Technical Service Bulletin (TSB) 2081193/1 to provide a software update solution for these problems.

This TSB applies to 2026 Audi A6 allroad, RS 6, RS 7, A8, S8, Q7, SQ7, Q8, SQ8, and RS Q8 vehicles equipped with PR Number IU4 and specific software versions (Address word 005F, 4572 or Address word 078E, 0718).

Symptoms and Warning Messages

If you own a 2026 Audi Q8 MMI Emergency Call Fault may be displayed, or you might encounter various problems with the MMI (Multi Media Interface) system's functions. These issues are typically software-related and affect the vehicle's infotainment and communication systems.

Affected Control Units

The software update detailed in TSB 2081193/1 targets several key control units within your Audi's electrical system:

• Android Embedded Device 2 (AED2): Identified by the control unit address DA 078E.
• Emergency Call Module Control Unit and Communication Unit (Connectivity Box): Identified by the control unit address DA 0075.
• Control Unit for Information Electronics (MIB3): Identified by the control unit address DA 005F.

Important Warnings for Owners and Technicians

Audi has provided specific instructions and warnings regarding this software update:

• Do Not Invoice Diagnostic Tests: Guided Fault Finding test plans should not be performed or invoiced if the issue is resolved by this TSB. Similarly, the USB-C stick and the process of loading the software onto it cannot be invoiced.
• Extended Update Time: A significant period of inactive time is expected during the software update. Technicians are advised that they can work on another vehicle during this process.
• Warranty Billing: Time stamps are not required for billing under warranty when performing this TSB.
• ODIS Update Required: A new test program for inputting the SVM code is used. Ensure the diagnostic tester has the latest ODIS software.
• USB Stick Handling: The vehicle uses acoustic signals and flashing lights to indicate when user input is required during and at the end of the test program, specifically for "SVM Authorized Multiple Code Entry." It is crucial to leave the USB stick inserted until instructed to remove it. The procedure will only work if the USB stick remains inserted throughout the download and update process.
• Update Sequence: Do not proceed to the second step of the update until the Android embedded device (DA 078E) update from step one has been completed.
• Media Type: You must not use an SD card with an adapter USB stick for this update.

Software Update Procedure Summary

The repair involves a multi-step software update using the ODIS-S diagnostic system and specific USB-C sticks. The process is divided into two main parts:

1. Manual Software Update for AED Control Unit (DA 078E)

This initial update is performed via the MMI's red menu. If a previous update attempt was aborted, technicians must verify the AED control unit (DA 078E) software version. The update process involves:

• Using ODIS-S in "Flash" mode.
• Selecting "SVM - special functions" to activate the update menu.
• Following ODIS instructions, including inserting a USB-C stick.
• The control unit will enter update mode, perform multiple resets, and the display image will change.
• After the update, the MMI will restart, and the home screen must fully initialize. Technicians then check the notification center for confirmation of the update's success.

2. SVM Code Entry for Other Control Units

Once the AED control unit update is complete, the SVM code FLIGHTON0075MLB,ZGDOIP,CL3DA002,TGU1MDMVB,CL3DA001,FLIGHTOFF0075MLB is entered using the "SVM - Authorized Multiple Code Entry" function in ODIS-S "Flash" mode. This code facilitates the software update for the emergency call module (DA 0075) and information electronics (DA 005F).

After the software updates, the vehicle is put into bus sleep mode for at least 30 minutes to prevent functional impairments. Finally, the emergency call LED in the roof module is checked to ensure it lights up green, and the diagnostic session is concluded.

Required Parts and Tools

To perform this software update, two specific USB-C sticks are required. The software for the respective control units must be downloaded onto these sticks:

• For AED Control Unit (DA 078E): Part number 8W0906961GS
• For Control Unit 1 for Information Electronics (DA 005F) MIB3: Part number 8W0906961GK

Technicians should ensure they are using the latest ODIS software for the diagnostic tester.
