New to Mini ownership. Got my 2013 Cooper and have been very pleased and excited...until I noticed the noise. It is intermittent, when going over a “sharp” bump in the road. It sounds like two small metal rods “clinking” together. From the drivers seat is sounds like behind and to the right side. It’s not the hatch latch, nor the seat latches. I plugged both rear seat belts in. I made sure the jack pieces were well secured. I even found a few loose light bulbs roaming around the rear right hand tunnel. My wife helpfully suggested turning up the radio...but I can’t let this rest. Any suggestions are much appreciated.
