Audi A6 C6 - MMI Not Working: Black Screen, Buttons Unresponsive, Diagnostics Errors

Hello!
As the topic does not start MMI. The black screen does not react to the on button.

Diagnostics Bus Diagnostic: Standard

Controller Electrical Optical
19-CAN Gateway OK ERROR
07-Control Head ERROR ERROR
0E-Media Player 1 ERROR ERROR
47-Sound System OK ERROR
56-Radio ERROR ERROR
37-Navigation ERROR ERROR
Fuses checked. Any hint?

It is possible that you have a bus interruption, you have to unplug the bridge plugs from the modules and check if they are glowing, if any signal passes, then you are fastening the bridge one by one to exclude the module causing the error.

Computer mmi is flooded.

19-CAN Gateway I found a clipboard / communication is, error 00384 - Optical Databus 011 - Open Circuit - Intermittent
47-Sound System - amplifier in the trunk / lack of communication
07-Control Head the control panel of the gearshift wheel / it has no connection with light / no communication
Navigation 37 in the clipboard / LEDs flash alternately / no communication
display and on the board, otherwise I found nothing else.
Gzie is:
0E-Media Player 1

MMI computer which and where ???

Auto undressed but computer mmi can not find.

Replace it with a lot of buttons and two knobs

Which diodes?

What navi do you have there?

2G HIGH, 2G BASIC or 3G?

Make optical bus test with damping + 3dB

Mmi does not work for me either, the loudspeakers are knocking and the optical bus test is attached.

Error in Gateway: 384 - optical data cable - permanent failure;
information electronics and radio - no communication;

Today I unplugged the amplifier in the trunk and plugged it in and I have this status:

Where to start ? I still do not connect to the radio and the mmi module, there are also no optics in the plug in the trunk near the amplifier.

And how did you solve the problem, buddy? Because I have just the same thing. When turning on, you only hear a moment as if something was read from the disk and that's it. I don't even have anyone in my town to let him check

Hello, gentlemen, the same problem .. I had a flooded radio and amplifier. I dried, overheated and cleaned in February. Now I only have the startup screen after turning on and it turns off immediately. Check all the elements of the navi amplifier and the radio if they were not flooded. In the Audi C6, these elements are often flooded. Can anyone tell where to buy such a bridge because I do not have any old plugs. And of course, will anyone boast about working out this fault ??

Hello everyone!

I am refreshing the topic as I too have been hit by a similar problem.
In my case, after the battery problems, a little fuss was made, MMI 2g HIGH stopped working .
Audi A6 C6 Prelift 2005.

I scanned the optics with VCDs. The results came out as below.
My question is. What are the components causing the errors and where to look for them?
- 07-Operating/display unit. (control head)
- 0E-Media Player 1

Hello everyone, I also have the same problem, I am looking for hints, no connection on the fiber optics, I am going through the devices one by one , I have replaced the MMI controller , buttons near the gears, now the logo is showing on the display and still dark, I have done the bridges and only connected the radio and it does not work either?
