Just joined,not an owner yet but looking at a Z3, early 1999, 1.9 , 94k. Have inspected most things using the guides on this site & chatting to another owner. I test drove it a few days ago & after less than half a mile there was an almighty thump from underneath , looking in the rear view mirror a " bit" had fallen off that seemed to resemble the size of a break calliper! Gently breaking & pulling in safely my passenger rushed off to retrieve the " bit ". Once back in the car he explained that it was an exhaust damper. What puzzles me is that this " bit" which weighs about a kilo, doesn't seem to do anything , my question therefore is.....does it ?
Will the car need a new one to pass an MOT ?
