i purchased a used 99 328i...it's beautiful (i told my recent ex girlfriend that it was her replacement- hee hee)...but i have noticed a "clicking" that seems to be coming from the passenger side front wheel. It's not all the time- and it goes away as soon as ANY pressure is applied to the brakes. I asked the sales person <which was from a VW dealership> what this was...and he said "Oh, that is a plastic clip that indicates your brakes are 50% worn" there is no drivability problems, just the annoying clicking from time to time. Has anyone had this problem? and if so...is it serious? thanks!
