Initial publication

The vehicle is a MY2016 A6, A7, S6, S7, or RS7 and the customer states that after using the front, rear, or topview camera system, the audio is muted. Additionally, the customer’s vehicle is equipped with MMI Navigation
plus (MIB2 High Nav; PR code “7UG”).

Technical Background
The condition is the result of an MMI software bug and can be fixed by updating the MMI software. The condition
only occurs after the vehicle has been allowed to enter sleep mode. The customer typically states that the
condition only happens after using the backup camera when leaving in the morning or when returning home at the
end of the day.

Production Solution
The solution was introduced into series production starting with MY2017 vehicles.

 Install this program onto the ODIS tester by double clicking the file labeled “setup_V1.0.exe”. If IT policies
restrict the installation of programs on the ODIS tester then please ask the IT department to perform the
install.
Tip: It is not possible to use this program on any other PC or laptop due to the mirror server security
certificate restrictions.
 Installation instructions and user manual are located in the same directory and is labeled
“2017_03_21_Benutzerhandbuch_SD_Creator_V_1.0_EN_.pdf”.
 Once the program is installed it will place an icon labeled “SD Creator” on the desktop.
 Open the application by double clicking the icon.
 Once opened you will need to enter the mirror server URL into the settings tab.
 Enter “mirrorserver2.vwhub.com” (without quotes) into the server section listed under the “settings” tab.
 Next click “Test connection” and ensure that there are no errors. If needed you can select a different
brand and then reselect “Audi” from the drop down menu at the top of the window. This will refresh the
application.
Using the SD Creator:
 You will need the SD card part number listed in the “Required Parts and Tools” section to find the
software.
 Place the part number into the part number field of the program and hit the “play button”.
 Reference pages 15-18 of the user manual,
“2017_03_21_Benutzerhandbuch_SD_Creator_V_1.0_EN_.pdf”.
Tip: Typical setup time to download the data and have a working SD card is about 1-2hrs depending
on network speed. Prepare the SD card long before starting the repair.
3. Connect a charger or battery maintainer to the vehicle that is capable of maintaining the vehicle voltage at
the appropriate levels (check current capacity of maintainer). Turn off all unnecessary battery consumers,
such as LED DRL’s, HVAC blower, radio volume mute, etc.).
4. Follow the steps listed in the attached document
“audi_mib_two_high_nav_plus_software_update_instructions.pdf” to complete the update process.
For MIB2 systems there are now two methods for performing software updates. It is no longer required to
manually enter the Red Engineering Update menu. MIB2 software updates are now controlled by the SVM
code in ODIS. Using this process the update is fully automated.
If there is an outage with SVM, the old method is still available to use, but not preferred.
Method 1: (Preferred method). Using ODIS Flash, enter the SVM code MI2HNAR0539C7 into ODIS and
follow the instructions in ODIS to start the update process (see attached document
“audi_mib_two_high_nav_plus_software_update_instructions.pdf”).

Method 2: (To be used only if SVM server issues occur). Enter the red engineering update menu, insert SD
card, perform MMI update, and then perform the SVM documentation feedback (see attached document
“mib_mmi_shortcut_keys.pdf”).
5. Only if Method 2 was used, perform the SVM feedback documentation of the information electronics control
module 1, J794 (address word 005F – MMI) with SVM using the SVM code MI2HNAR0539C7. To access
SVM, within ODIS start GFF >> Diagnosis >> Special functions >> Software Version Management >> SVM
code input.
6. Test the functionality of the MMI system and verify the audio is not muted after exiting the backup camera.
