I must have grounded the car (M Sport) and mine did this. Turns out it was a broken exhaust bracket; one bolt had come off and it was secured with the other. I imagined all types of potential fault, but it turned out to be something more simple.

is it a faint knocking only when your slow moving over mildly rough surface? could it be drop links?
