My Ride: 2008 BMW 550i Sport
Carbon Black Metallic/Cream Beige
Manny tranny and other stuff
Recently gone, but never forgotten:
2005 Ford Mustang GT (hence the name)
Torch Red/Crimson
Manny tranny and every option available for that year
2002 Chrysler 300M Special
Brilliant Black/Light Taupe/Dark Slate
Autostick and goo-gobs of neat features that I will sorely miss
The first night I brought my 550i Sport home and parked it in the garage, when I got out, there was a symphony of all sorts of machine noises that seemed to emanate from underneath the car for several seconds. If I recall, there were three distinct ones. Two of them are gone (or I just don't notice them anymore), but now everytime I open a door, any door, theres an electric motor noise from under the car.
What the heck is all the fuss about under there??

The noises you are hearing when you exit the car after parking it is the car getting ready to go into sleep mode. The noises you hear when you open the door/Trunk or unlock the car is the car getting ready for operation.

I could be mistaken, but seemed logical to me

I usually notice it in the morning, when the car is in the garage. As soon as I open the driver's door, it happens. The sound is definitely *not* inside the car. Even if it was, it doesn't sound like a CD or DVD spinning up, not even close. Its more like a hydralic motor. It cycles on for about 1 second, and I think there is a light click or maybe something else. It sounds like it is coming from under the chassis, toward the rear. Something to do with dynamic drive? Maybe a fuel pump?
Maybe I should throw a microphone under the car and post the sound bite. Won't happen until I get the car back from the dealer, though. Ah, yes, and I'll need to buy a microphone.

My Ride: 2011, X6 Hybrid . Alpine White , every option. 20" Conti' NON runflats,OEM trunk spoiler , LUX V3 AE's , HP Thunder Fogs , custom front bumper reflector delete........
I spent 5 hours detailing my car a few weeks back and I swore it was talking like R2D2 the whole time These cars are highly computerized and very self monitoring, so this "stuff" is going on a lot , I'm sure Rudy will give us the technical details but rest assured it is all normal ..... or as normal as new BMWs get .....Good Luck

My car does the same thing. I, too, have thought to ask this question.

This isn't my first car with all sorts of electronic gadgets. But it is the first one that makes all kinds of body noises on its own. BMW really takes it seriously when they call it a "Machine!" With all those noises, I wonder if it won't convert into a Battle Mech and post sentry in front of my house! 
How cool would that be?!

I dont lock my car all the time, so how does all this stuff initiate if I dont use the FOB until I insert it into the dash and am ready to go (non-comfort access)?
