beeping noise when unlocking the car?

i have a 2006 bmw 325xi and recently when ive been going to school in the morning my car for some reason makes a beep noise when i unlock the car. It seems like it only does this after its been sitting in the cold for a long time, because after it does it once, it wont do it again until it sits overnight. ive only had the car for 4 months, but it just started doing this last week.

can someone explain this?

Is it a beep or more of a hydraulic whine?

If its a hydraulic whine then I would think it's the fuel pump priming. Perfectly normal so don't worry about it.

An actual beep though, I have no idea.

I just remember at some point in time I have heard like and hydraulic noise in the center of the console where the air vents are as soon as I get in the car, kind of like the same noise the mirrors do when they unfold but this time is inside the car. It happened only a few times in all these years. Has anyone experience this?

Note: its not when the car has been shut off after a few minutes, I know this noise always happens, this is the inside vents that closes down to avoid outside air and smell coming inside the car.. I would think?

hydraulic whine? can someone explain what that sounds like? cause when I unlock my car it sounds like a short beep or maybe even a low squeak on the drivers side door.

I have a different beeping problem!!!

when I unlock my car e90 320d 2006, its starts to beep after 10 - 15 seconds, and the beeps last for about 1 minute, and does not matter you start the engine or not, drive or not.
and there is no warnings on the screen or else.

maybe someone knows what is that and how to get it off?

yeah that's the fuel pump priming. Once you unlock the car and before your hit the ignition, the fuel pump primes so the car doesn't try to start dry.
