when i open the door on my car after it sits for a day or two i hear a pump cycle on and off, i think its the fuel pump since it sounds like its coming from the back of the car.
is this normal....or it it yet another gremlin to add to my list?

that's your car waking up 
. people get freaked out when they hear my car and know nothing about BMW's. if you turn off you car and wait for a few minutes you will hear some of the modules goin "to sleep".

Perfectly normal. The loudest noise comes from the fuel pump being primed.

does your car do the same thing? you hear a pump cycle when it wakes up? is that the fuel pump pressurizing the system so it will start quickly?

My car just started to do it. 2006 550. The CD player was replaced, and they must of updated all the software. I never noticed the sound prior to this update. The update also allows the radio to dispay radio station call signs, artists and song names.
