M sport does not give you dynamic dampers.
After you select msport package you'll note the dynamic damper control remains unselected. You have to opt into the optional dampers or you don't get 'em.
Don't believe us... go talk to your friendly BMW sales guy...
See the pics below... msport selected with and without dynamic dampers... see you do have to pay for 'em.
