Hi there - a common cause of this problem with BMWs is loose sway bar links. It is also possible that one of the many heat shields has come loose somehow and is rattling. I recommend a noise inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.
