Brought it into my mechanic and he said its normal but my friends F30 doesn't make this sound.
Bought the car 2 weeks ago and didn't realize it at the dealership so I have no idea what it could be.
The car is a 2013 328i X-Drive

Is it that drone sound after you lift your foot off the brake? Have you checked your fluid?

In what context is it making that drone, speed, braking effort, etc.

Just looking and listening to the video, looks like very light braking. The sound you can sometimes 'deliberately' make, letting the car creep on the brakes, down a slope. How do I know?

Breaking, I happens with very very light breaking. It does it no matter what, if i get off the breaks fast it does it slightly and it drags out like in the video when im creeping forwards or backwards in the car.

Sounds like it's groaning when you lift off the pedal. There are cars that technically do that for some odd reason. Not really sure what the remedy is

"It does it no matter what..." is the concerning bit. I mentioned my 'forced' example, but it doesn't "just do it", it is on demand.

I'm suspicious of a slightly sticking calliper. Or the brake pad assemblies are in need of removing and cleaning/greasing, etc.

Update: Break fluid is fine. Tried the 40-0 break test to see if it was the rotors that needed a little breaking in and when you slam on the breaks it feels like there might be something on one of the rotors and they creek hella loud

I'll bring it back in on Monday to get checked again. It's the only thing really bothering me

Ya, this sounds like something isn't right with the caliper/pads/rotor. Pull off the wheel and see if something stands out to you. See if you can have someone outside the car see where the noise is actually originating from

Update: Did the whole 40-0mph break test a couple times on the way home. Breaks no longer make the sound as much but now the breaks screech when slowing down. My theory is that the dealership did put new breaks on(probably some cheap breaks) and it needs to be broken in?

Will update again if the problem persist
