hey I am new here just picked up a marina bay blue m5c 3 weeks ago and was brought in for the 2000km service today.

This morning before I service I noticed a clunking noise coming from the rear of the vehicle when downshifting or giving the car half throttle around 2-3k rpm.

The dealer said it could be the drift shaft making noise. They have had a few previous m5 have a similar issue. There could be a loose piece of plastic in the area? have anyone had similar issues? just frustrated this is happening on a brand new car. Hopefully its nothing serious. Besides that the car has been perfect and couldn't wait to finish the service to really push the car!!

ps I have to confess I did push the car to 6-7k rpm at full throttle up to 230kph yesterday right be fore noticed the noise this morning.....
