E87 idrive not opening

[filroz]

Hello,
( E87 facelift 118d automatic )
This morning I went to my car and my idrive screen did not flip up.. I can still hear the little engine trying to open but no movement whatsoever. I tried to check it a bit and a little plastic broken cogwhell came out of the mechanism on the left. Do I need to replace the whole unit or I should try to dismantle it and take a look ? Did it happen to anybody before ? I googled a bit and didnt see many results as I think not many BMWs have flip up screens ( I think only 1s and Z4s had , correct me if Im wrong ).

In my friend car, E83 X3 flip screen did not want to open. After dissasembly i found broken parts. O you know where i can buy this part. I do not want to buy new screen. Sorry for background, but i was after few beers and yesterday it looked ok:)
