2022-2023 Audi MMI Software Update for Infotainment Issues

Owners of 2022-2023 Audi vehicles equipped with the MIB3 infotainment system may experience a range of functionality problems or see an "Emergency call fault" message displayed in the instrument cluster. These issues stem from outdated software within the MMI system and the emergency call module. Audi has released Technical Service Bulletin (TSB) 2079133/1 to provide a comprehensive software update to address these concerns.

This Audi MMI software update aims to restore full functionality to the infotainment system and ensure proper operation of the emergency call service.

Symptoms of MMI and Emergency Call System Issues

Owners may notice various problems with their MMI system, indicating a need for the Audi MMI software update. These can include:

• Problems controlling infotainment functions using buttons, controls, or the screen.
• Malfunctions with screen settings or general system settings.
• Issues with telephony functions, including telephone operation.
• Problems with radio operation, navigation, and MMI drive device functions.
• Infotainment system operation difficulties when using the multifunction steering wheel.
• Malfunctions related to Telematics and online services.
• Media playback issues.
• Problems with operation, control, or speech input.
• Audio, video, television functionality problems, including audio playback and settings.
• An "Emergency call fault" message appearing in the instrument cluster, often accompanied by interference display symbols for the emergency call service.

Diagnosis and Trigger Conditions

When diagnosing these issues, technicians typically find that the vehicle's diagnostic address 005F (Information electronics 1) has a software version below 3900. The presence of diagnostic entries logged in diagnostic address 0075 (emergency call module) also indicates the need for this update. These software-related issues are the primary cause of the reported symptoms.

Important Warnings for Owners and Technicians

Audi has provided specific instructions and warnings regarding this TSB:

• Do not perform Guided Fault Finding test plans for diagnostic entries in 0075: If diagnostic entries are logged in diagnostic address 0075 and are resolved by this software update, the Guided Fault Finding test plans for these entries should not be carried out and cannot be invoiced under warranty.
• USB-C Stick Requirement: Technicians must prepare the required USB-C sticks before starting the repair. It is critical that an SD card with an adapter USB stick is not used for this procedure.
• Warranty Billing: When performing this TSB, time stamps are not required for billing under warranty. This allows technicians to work on other vehicles simultaneously, and the update can even be performed by non-productive personnel.

Repair Procedure Summary

The repair involves a comprehensive software update for both the emergency call module (0075) and information electronics (005F) using a specific SVM code chain. This Audi MMI software update is performed using the "SVM – Multiple authorised code inputs" function in "Flash" mode.

1. Software Update Preparation: Technicians connect a tester, start ODIS, and enter "Flash" mode. They then use the "Function Authorized Multiple Code Entry" to input the SVM code chain. For A4, A5, A6, A7, A8, Q5, Q7, Q8, and e-tron (GE) models, the SVM code is FLIGHTON0075MLB,ZGDOIP,CL37A001US,TGU1MDMVB,CL37A002US,FLIGHTOFF0075MLB. For Q3 models, the SVM code is TGU1MDMVB,CL37A001US,CL37A002US. These codes should be scanned via QR code or copied and pasted exactly.
2. Media Insertion: A prepared USB-C stick containing the update software is inserted into the vehicle. The program runs automatically, and the USB-C stick can be removed once complete.
3. Bus Sleep Mode: After the software update, the vehicle must be put into bus sleep mode. Then, the ignition is switched back on, and the MMI is started.
4. Verification: The emergency call LED in the roof module should light up green again, confirming successful update. The diagnostic session is then ended, and the log is sent to GFF paperless.

If the update procedure is interrupted, technicians are instructed to repeat step 1, and the test program will automatically complete the missing part of the update.

Required Tools and Parts

Performing this Audi MMI software update requires specific tools and media:

• USB-C Sticks: Required for the update. These must comply with the USB 2.0 specification (32GB) and be formatted correctly. Larger capacity USB sticks should not be used due to different formatting processes.
• Flash Media Creator (FMC): Used to download the software with the correct part number onto the USB-C stick.
• ODIS Update: The tester used must have the latest ODIS update, as a newly developed test program for SVM code input is included in the ODIS software.

Specific part numbers for the MIB3 update media, depending on the vehicle type and Sirius XM configuration, include:

• Audi Q3 without Sirius (I8W with QV0): 8W0.906.961.DJ
• Audi Q3 with Sirius (I8W with QV3): 8W0.906.961.GA
• Audi Q3 without Sirius (I8Y with QV0): 8W0.906.961.DK
• Audi Q3 with Sirius (I8Y with QV3): 8W0.906.961.FT
• Audi A4, A5, Q5 without Sirius (PR number QV0): 8W0.906.961.DK
• Audi A4, A5, Q5 with Sirius (PR number QV3): 8W0.906.961.FT
• Audi A6, A7, Q7, Q8, A8, e-tron without Sirius (PR number QV0): 8W0.906.961.DL
• Audi A6, A7, Q7, Q8, A8, e-tron with Sirius (PR number QV3): 8W0.906.961.FS
