Buzzing noise when unlocking car

[F36 435i M]

Hi guys,

Got a M240i about a month ago and noticed this weird buzzing noise for about 5 seconds or so when unlocking the car. It's louder with the bonnet open, this is when I first heard it. I've attached a link below to me unlocking the car, you can just about hear it. Is this normal?

I've seen online that it could potentially be the valvetronic motor, but that noise sounds like an aggressive ticking sound which is completely different to what my car makes, and the buzzing noise I'm hearing is far more quiet. Is this noise I'm hearing just the fuel pump preparing the car?

Thanks in advance.

Fuel pump priming. Supposed to do that, it’s a beautiful sound

When I first got it, I had the comfort entry turned on. I felt bad walking around the car cleaning it since it would trigger the priming when I'm not even going anywhere. So I turned that feature off.
