I am experiencing this noise coming from somewhere inside (near the centre) the dashboard when the car is stopped in the traffic and is at the 'D' gear. The noise disappear when Neutral gear is selected. Do you thing it is easy for the dealer to locate the loose part creating this noise? Any ideas of what might be?

Ive got the same thing, gonna ask the dealers when she goes in in the next couple of weeks Now - 2017 BMW X3 M Sport Carbon Black
Gone - 2014 BMW X3 M Sport Space Grey, faultless!
Gone - 2011 Freelander 2 SD4 HSE Bali Blue with xenons
Gone - 2008 Freelander 2 TD4 HSE Rimini Red with bodykit

I had this as well and found it only happened when i had cd's in the multichanger, now use an ipod and no longer get the rattle.
