I tried to put a new license plate cover on my 328i trunk lid. The srews (not original screws - some aftermarket junk that car came with) for the license plate were rusted but still had good threads. I could not get them to back out of the upper white plastic grommets, so I had to cut the heads off and pry the grommets out by force (accidently scratching the paint and warping the sheet metal). What is up with these grommets, has anyone else had this problem? How can it be prevented? I ordered new ones grommets from BMW and new factory LP screws too, but am reluctant to use this setup again. All this for a stupid LP frame and plastic cover! Any one else have this problem?
