So it looks like the previous owner tried to open the door with their foot, and broke the clip that holds the door skin. It’s the driver door. Bottom right corner. The clip holds the external skin on. This isn’t an interior panel clip.
I see that the door skin is plastic, and has a receptical for a clip.
I see that the door frame has a threaded adjuster that holds a clip too, but the threaded adjuster doesn’t seem to be shaped in a way that allows it to connect to the door skin.
What seems to be missing is the clip that holds the external plastic door skin, to that threaded adjuster.
I’m trying like crazy to find a bmw exploded view that identifies that piece, and assign it a number that i can order.
