2020-2026 Audi MIB3 Software Update Instructions TSB

Audi has issued Technical Service Bulletin (TSB) 2060523/4, titled "91 MIB3: Software Update Instructions," to guide technicians through the process of updating the MIB3 MMI system software. This TSB, released on April 22, 2025, is crucial for maintaining the optimal performance of your vehicle's information, navigation, communication, and entertainment functions.

This TSB specifically addresses issues related to software updates for the information electronics control module, which can manifest as general "control modules" or "error message" complaints within the MMI system.

Important Warnings for Owners

Audi provides specific instructions to ensure a successful software update and prevent potential issues:

• USB-C Stick vs. SD Card: "You must not use an SD card with an adapter USB stick." Instead, "Do not use a USB SD card reader and an SD card to attempt the update." A dedicated USB-C flash drive is required.
• USB-C Stick Formatting: The USB flash drive must be formatted as "NTFS." To achieve this, select "NTFS" from the "File Format" dropdown within the SD Creator program.
• USB-C Stick Capacity: For general updates, a 32GB USB-C stick is recommended. "USB-C sticks with a higher storage capacity should not be used as these types of USB sticks have a different formatting process." However, for navigation databases, a 64GB USB-C stick is necessary.
• Warranty Claims: "This TSB cannot be used for invoicing Method 1." Additionally, "The USB-C stick and downloading the software via the SD creator cannot be invoiced." If your vehicle is no longer under warranty, "If the vehicle is outside of any warranty, this Technical Service Bulletin is informational only."

Technical Background

The MIB3 MMI system was initially introduced in the 2020 model year for Audi A4/A5 models. By the 2021 model year, all Audi vehicles were equipped with the MIB3 system. This widespread adoption means that a consistent approach to software updates, such as the Audi MIB3 software update, is essential.

For more detailed information on preparing the necessary media, technicians are directed to TSB 2047812, which covers the "00 SD Creator: how to set up and use the SD Creator for obtaining vehicle software updates via the MirrorServer."

Software Update Procedure Overview

The TSB outlines two primary methods for performing an Audi MIB3 software update:

1. General MMI Software Update Process (Method 1): This is the standard procedure utilizing the ODIS Tester and SVM codes.
2. Manual Update Process (Method 2): This method is used if the initial update is cancelled and involves accessing the red engineering menu.

Preparing the USB-C Stick

Software updates for the MIB3 system require a USB-C stick as an external data storage device. This medium is used to apply new control unit software for various components, including information electronics, volume control, Android control unit, or navigation maps. It is critical to prepare the required USB-C sticks before starting the repair, as some repairs may require multiple sticks.

To prepare the USB-C stick:

• Ensure it is a 32GB USB-C stick that complies with USB 2.0 specifications (or 64GB for navigation databases).
• Download the software with the part number specified in the applicable TSB onto the USB-C stick using the SD Creator program.
• Format the USB-C stick to "NTFS" using the SD Creator program, as shown in Figure 1 of the TSB.

Required Tools and Equipment

To perform the Audi MIB3 software update, technicians will need the following:

• ODIS Tester: For diagnostic and programming functions.
• SVM Code: Specific codes are required for individual updates or SVM code chains.
• USB Flash Drive: A properly formatted USB-C stick (32GB or 64GB for navigation) containing the update software.

General MMI Software Update Process (Method 1)

This method is the primary way to perform the Audi MIB3 software update:

1. Deactivate Bluetooth or Wi-Fi connections in ODIS.
2. Connect the diagnostic head to the vehicle using a USB cable.
3. Open the "Flash" feature in ODIS, select "SVM code input or SVM – Authorized multiple code entry," and click "Perform check."
4. Enter the SVM code for the update. The system will verify its applicability for the vehicle and display the update medium's part number.
5. Insert the Update USB flash drive into the USB port in the center console. The tester will guide you through the update, configure the new software, and report the build status to the server. Always follow the commands on the tester screen.
6. After a successful update, remove the USB flash drive, which can be reused for other vehicles.

If the Update is Cancelled (Method 2)

If the update process is interrupted or cancelled, a manual method can be used:

1. Enter the red engineering menu by touching the screen with two fingers in the top right corner (as illustrated in Figure 2 of the TSB).
2. Use the volume control to navigate the red engineering menu, select "Update," and choose USB as the source. Scroll down to view all control units to be updated and start the process.
3. After a successful manual update, re-run the SVM code with the ODIS tester to ensure proper configuration and reporting to the SVM server.

General Tips and Tricks for MIB3 Software Updates

• If the update aborts with an MMI display message, try to continue by unplugging and re-plugging the USB stick. Wait two minutes each time for the MMI to read the stick.
• If issues persist, reformat the USB stick to NTFS and re-download the software via the SD Creator, or try a different USB stick.
• If the vehicle has multiple USB connections, try switching ports.
• A terminal 30 reset of the infotainment control unit 5F for at least 30 minutes can help. Allow the system to fully start before attempting the update again.
• Repeat the update via the red engineering menu (REM) if necessary.
• After any successful update, use the SVM code for feedback documentation to fully complete the process.
