I've had this happen a few times in my 528i. Sound comes from the back/trunk, almost like a small motor turning/cranking, and then it stops. Happens when I stop and am getting out of the car. Haven't had it happen enough, or during a certain chain of events to be able to replicate and fix

fuel pump?
