Hello everyone,
This is my first post on audiforums. Im having problems with my q7. The mmi system doesnt work, the screen turns on for about 3 second then turns off. It works whenever it wants to (but rarely does) ive been having this problem for about a week now. I dont have warranty on it, it has expired. Ive been to the dealer and theyre asking about $300 for doagnostics test but money is really tight right now. I was wondering if anyone knows the solution to this! Nothing has spilled on it i know for a fact. I was thinking if its maybe a bug in the system or maybe if its a fuse.
What i have tried is rebooting the system with 3 button method.. That has not worked..
I also checked the fuses in the trunk and on the passenger side fuse box, they were all good

MMI not working
I washed my Q7 and all of a sudden the MMI stopped working. Took it to the dealership and they told me the "amp in the back " was blown. They replaced it and then told me it blew the circuit board under the MMI. $2500 later they fixed it.

Q7 Quattro Sline 08 - MMI Fault
HI all good replies in this forun.
My MMI also is completely dead. No Display and no sound and no Lights on the Panel.
Can someone advise what this could be,
Forum says could be from Fuse to Amplifier.
I checked the fuse and its fine. is there anyway to check if in the amplifier before remove this?
I t might be this as two days before it happened i washed my car
Many thanks all for your help

That was the beginning stages that I encountered before my mmi shut down. These are the early stages so your best bet would be to take your car to a dealer or audi specialist and have them take a look at your amp. You can maybe have it dried and have the battery recharged.
