MMI screen is stuck out and not working its just black

[daviesbike]

well the screen came out today and decided to stay out and its just a black screen no picture no radio or cd or nothing cant use sat nav cant change the air ride nothing ahhh its one thing after another i have looked at all the fuses in case it was a fuse but nothing
and when i get in the car when its been locked you can hear the speakers making a noise for a few seconds then it just stops and its dead just no life in it

is there any thing i can do ?

i dont have any vag com that works with my car although i may have in the next few days thanks to A8 doc

god the amount of times i need vag com and just have not got it its silly now

any help with this would be great

Ps where are all the brains and electrics for the MMi as i did drive through some fairly deep water the other day and i have had no problem with the MMi in the past until now im sure you have all seen the flooding in my area at the moment
