Rattle upon warm startup (video inside)

I've got an '06 325i that's got this weird rattling noise that only shows itself when starting the car on a warm engine. Can't remember it ever happening on a cold start.

Here's a video. Might need to turn the volume up a bit.

I've noticed the car has to sit for 10 or so minutes before this sound will come out. If you turn it off and right back on within just a couple minutes, it's not there.

Already had the blower motor replaced about a year ago and I kinda doubt it's that because I've never heard it when just turning on the accessories. Seems the engine has to be started too for it to happen.

Happens in warm and cold weather.

Anyone have any idea what this could be/has anyone had this before?

Does it do it everytime or at random?

I know my 328i rattles on random other owners have the same problem.
