Pre-requisites
MMI 3G+ systems with relevant PR no.: MMI Navigation Plus – 7T6
Obtain the needed software updates
Audi A1
- 8R0 906 961 EC –HN+_EU_AU210_K0900 (A1)
Audi A4-A5-Q5-Q7
- 8R0 906 961 FC –HN+_EU_AU3G_K_0942 (A4/A5/Q5/Q7)
Audi Q3-A6-A7-A8
- 8R0 906 961 FB –HN+R_EU_AU_K0942 (Q3/A6/A7/A8)
A high quality SD Class 10 for faster (and safer) file operations. The separate firmware upgrades are bellow 1GB in size but the map is 29.1 GB hence the 32GB SD.
Activate hidden “green” menu.
Prepare SD card with the firmware.
Format the card with FAT32 file system and then copy the files from the first software update. The card should look similar to this:
Important: Do not conduct any diagnostic work using the VAS tester, as well as any other actions
Important: Remove the SIM card from MMI
Important: Do not remove the SD card with the firmware from the MMI during the update
User defined update
Sometimes things go wrong and maybe the update is not completed. When this happen you can use the “User Defined” mode for make a manual selection of what upgrade or install.
For User defined update detail information,check here:Audi MMI USER DEFINED UPDATE
Bose Specific
Remove all checkmarks from component BoseG3_*. It should look like that – N or N/A:
Updating the firmware
Open “Engineering Menu” pressing the CAR button and immediately after that the BACK button.
Hold both buttons pressed for a few seconds. The following screen will appear.
Insert the SD card with the firmware in slot 1
Press the “Update” option using the MMI Control Panel.
Scroll down with the big knob and select the source in the menu (SD 1) pressing it.
Select the firmware pressing the big knob once
Select “Standard”
Caution: If your car is equipped with BOSE (8RQ or 8RY) sound system and don’t know how to recode it… we recommend that you unselect it from list (using User-Defined Mode) before update.
Or you can use the fiber optic loop adapter 4E0973802
You will see a list with all categories that firmware will update
Scroll to bottom and press “Start update”
After several minutes/hours (it depends that what it has to update and the speed of your SD) the firmware update will be done. Scroll to bottom and press “Continue”. On the next screen select the “Abort documentation” and the MMI will reboot.
Once the system has rebooted, the download application may show a screen that displays the update progress of various devices. As soon as all devices have registered with the upgrade application, the update process is activated and the progress is shown on screen. The system may
reboot many times during the update and programming session. This is carried out completely automatically and does not require you to take any action. Once the system has rebooted, updating is continued and the “Download progress” screen is displayed many times.
Repeat this step until you reach K0900 as a current version (train version/MU software)
Update the MAP
Optional:Removing the old map is optional. However, is highly recommendable.
Benefits are:
Possibly avoid the Fault Code 03175 – Invalid Data Set error
Avoid errors while copying the map (out of size, slow write speed)
There are no files of the old map into the new map
Open Green Menu (Press CAR and MENU and hold it)
Go to nav/databaseupdate Select “Delete database (will need reboot)” and click it.
Wait until system removes the data.
When it finished. Reboot your MMI using the 3 button
Open Green Menu (Press CAR and MENU and hold it)
Go to nav/databaseupdate
Select “Delete Nav HDD partitionDownload game winning eleven ps1 iso. ” and click it.
Wait until system removes the data. When it finished, reboot your MMI using the 3 button
Format your SD in FAT32.
Copy the root of your map in the SD (like picture below)
Open “Engineering Menu” pressing the CAR button and immediately after that the BACK button.
Hold both buttons pressed for a few seconds. The following screen will appear. (MU Software should be 0900 by now)
Insert the SD card with the map in slot 1
Press the “Update” option using the MMI Control Panel.
Scroll down with the big knob and select the source in the menu (SD 1) pressing it.
Select the map pressing the big knob once (In your case the version will be ECE 6.22.4)
Press “Start update” and then “Start”
After around 1.5 hours the map update will be done, just select the “Documentation Cancel/Abort Information” and the MMI will reboot.
Device Summary screen is displayed in the subsequent overview screen.
Scroll down and select “Continue“.
Because you don’t have connection to Audi SVM you have to “Cancel documentation” here. This is the reason for 03276 Please Check Software Version Management in 5F Information Electr.
Activator
Caution: Do NOT insert the SD until MMI has fully booted you can brick your unit!
Caution: Please double check that you’re using the correct activator for your firmware, using incorrect activator will result in a bricked (dead) MMI unit
Format your SD in FAT32.
Copy the root of your activation in the SD (like picture below)
Make sure that MMI is fully booted (press all buttons once RADIO CAR NAV MEDIA TEL).
Wait until all options are ok (no options in gray) even when all options are ok wait a minute more. K942 firmware and maps 2018 must already be installed
Insert the SD card into the 1st MMI slot.
We are waiting for ~ 15 seconds, if everything is done according to the instructions, the MMI itself off and reboot.
After that the card will work.
Activator made Keldo. A huge thanks to him!*
*Need clarification as some german teams claim that they did that activator long before Keldo start to work on MMI’s. Who is right and who is not I don’t know.
03175 – Invalid Data Set
Procedure is tested on the following vehicles
Open Green Menu (Press CAR and MENU and hold it) go to car/carmenuoperation. – Attention 1: for each line, add 1 to the current value. It is recommended to take pictures of the screen before proceeding to avoid any unpleasant manipulation. – Attention 2: do not forget to scroll down the list that is larger than the screen! – Leave the hidden menu with the “return” – Restarting the MMI (see procedure) – You can now check with VCDS: The 03175 is deleted!
– Go back into the hidden menu – Restore the original values by subtracting -1 from each line.

If you own a newer Audi (2004+), you may have option called MMI (Multi Media Interface) which control all your media player and display on your dash 7″ screen. Some are built-in the dash or flip up like the A8 D3. The MMI is actually a very simple system, but quite confusing for Dealers or Repair shop to troubleshoot when things failed and consumers will normally end up paying for the wrong diagnosis and good parts until the problem is finally fixed, i.e, they replaced the right one after many other trials and errors. It’s good to understand the system and sometimes you can fix or find the problem yourself and save money. It communicates with MOST (Media Oriented Systems Transport) optical bus.
Most dealers don’t offer software update for MMI 2G – The latest version is 4610. Don’t update software unless you need to add AMI because you will need to get back the instrument cluster functions that’s lost in the upgrade. I have upgraded mine and
Since the optical bus is connected in SERIES, first device out to then second device input and so on until it gets back to the first device input to complete a loop. Think of it as some Christmas lights string, one burned out, the whole string is OFF until you replace the correct bulb to complete the loop.
So, one morning after a heavy rain over night and your car parked outside, the sunroof drains were clogged, the water entered the car, you turn on the MMI and the screen comes up with the MMI screen for a minute and goes black. You can hear the clicking in the rear of the back seat in the trunk, but nothing happens. Some devices on the MOST bus is malfunctioned (broken), the optical (red led) signal got stuck somewhere and didn’t get back to the head unit (first device) input. It could be one device or more. Before you get panic, you should check all the fuses, especially the one in the trunk, just above the battery, that’s the fuse for Radio, Amplifier, Navigation and TV tuner. If you’re lucky, the fuse is blown, replace it may fix the problem, but if it’s still intact, you need more troubleshooting to do.
It’s a mandatory for Audi owners with MMI system to have is the optical bypass loop (female), at least one as spare in case the system is down. Audi dealers do have the originals, but it’s not necessary, any aftermarket female loop would do.
Most of Audi savvy people would normally rely on the VAGCOM or VCDS to troubleshoot the system, but they will end up replacing some good parts instead. VCDS or VAGCOM will report very confusing data because when one device failed, all devices will show up on VCDS as broken which doesn’t help us to find out which one is the culprit. I’ve created a video to show how falsely VCDS can report failures. The incompetent dealers or Indies will use the VCDS output to justify for their replacing good parts mistakes on customers expense.
Here are some of the common troubleshooting techniques that I’ve seen so far. Every time we push a button on the control panel, it will wake the MMI system and try to select the device connected to the button, when the MMI wakes up and check the MOST bus by sending signals to all devices and got stuck due to some devices not responding, it will shut itself, hence the MMI screen displayed for a few seconds then goes black. The device query restarts when any button is pushed. Only if the head unit is functioning.
1. When you push any button on the control panel: NAV, CAR, SETUP, CD, AMFM… etc, the MMI screen comes up and then goes black, it normally indicates the Head Unit (most expensive part of the system) is working. If it doesn’t, then it may be dead or the control panel itself is broken.
2. Sometimes, people spilled drinks over the control panel by mistakes, the control panel no longer works, but still, we can check to see which part of the control panel is bad by pushing one button at a time to see which button is bad. If the MMI welcome screen never shows up, the head unit is dead.
3. It’s also known that if the device is faulty, there won’t be any LED signal passing through, so if we unplug the optical cable of one device and it’s not blinking when a button is pushed (MMI wakes) then we can assume the device before this is faulty, check the device loop picture to see components relative to the loop.
4. If you have to replace the HU (head unit-4E0035729-4L0), you do need to get CP (Component Protection) removed by a dealer or your sound won’t work or you can swap the old eeprom to the new one but you need electronic soldering skill.
Remove and clean the circuit board, it may work after or to replace.
This is my understanding of the MMI system, it’s only for references and not guaranteed 100% accurate, use it to troubleshoot at your own risk. If you see something that I missed, please comment below so I can add to help other Audi Enthusiasts.
