Tapping noise when unlocked / locked (engine off)

[AKRM2C]

Hi everyone. Greetings. I have a question regarding a noise i have recently discovered (dont remember if it did it before). These past days i have been monitoring my car’s behaviour pretty close. Maybe its just me being paranoid

As the video i have dropped below, i discovered a small, controlled tapping noise when the car is unlocked (engine is completely off. and also does it when its being locked. It tapps constantly for about a minute, then it went silent. And as soon as i pressed the unlock/ lock button again, it starts tapping again for another minute than gone. No faults, checked through bimmerlink. I think its some sort of preparation fuel or something else. But just wondering if anyone knows about this.
