I think it is a vacuum sound. I tried my friend's car but it was normal. Mine has this high-pitched sound. Any solution yet?

I take my car into the shop this coming Tuesday. I'm hoping BMW actually tries to solve the problem vs making up some bullshit. Check out my 2nd video I just posted

I first noticed the sound one day inside my car while driving it with the radio off. If I turn off all of the climate control. The sound is still there.

I just looked over my engine bay and checked my vacuum lines and didn’t see or hear any hissing coming from them while the engine was on.

Just seeing of you figured out what's making the humming and buzzing sounds ?
I took mine to one dealer and they claim it's normal but I think that's pure bullshit. Said sound was coming from cooling system
