What is this part?
Today I found this part in my E55.
It was sitting loose under the front upper edge of the side-skirt in the LH front door opening. I think It has been there for a while because the top edge of the skirt is now bent where it was sitting.
It's clearly a hinge/pivot of some type. I can not see any MB part number on it.
Is this a part of the car, or a foreign object?
This is where I found it:
