my dealer installed a emblem w/ there logo on it.....my procedure was this....
Sprayed badge w/ water then took dental floss and ran it through the back and it came right off, I had a hair dryer ready if it didn't work to heat up the badge and melt the glue but it wasn't needed in this case but for the ///M3 emblem you may need it, now if you have a little glue residue left over just wipe done w/ a digreaser or in my case Simple Green.
I'm 100% sure you get it off w/ little effort so don't put too much elbow grease into also becareful not to let it drop and chip your paint
you need to put the black and white emblem on your car to complete your look
