I am looking at getting the bumper lowers colour coded on my '01 SE Tdi. I recently had the front bumper off to fit my ABT grille and noticed that the lowers are just clipped on. Did Audi do these as a pre-primed (smooth) part as well as the un-painted (dimpled) part? If they did does anyone have the part numbers. Also did the rear lower come with a cut out for a straight out tailpipe similar to the S3 ones? At the moment I don't want to go down the root of fitting S3 bumpers just making what I have look better. All advice appreciated. Pat J.
