Hello! Just got my -05 CLK 500 elegance coupe few weeks back, and my self-closing boot lid isn't self-closing anymore. It needed little help with hand when I bought the car, but now it only makes buzzing sound when I press close button, lid stays up and it has to be pushed down with force.

Where is the pump for this located? I heard that it may be just out of fluid, but I have no clue where to look for the pump. Any help is highly appreciated!!

EDIT: It seems to me that boot lid is operated by electric motor, which in my case isnīt working. All fuses were good and locking works fine, only that lids opening and closing motor seems to be out for some reason.

 

Does someone know what part number is that opening/closing motor and is there any online, worldwide shop I could buy new motor? Trunk is stiff to open and close now, and I need it every time I go to shop groceries.
