STrange Noise

Hey Everyone. I do not understand where this sound comes from but it sounds exactly like side mirror folding or mirror adjusting . I drove 2 times today and it happened 2 times. I do not know what cause this problem but it is annoying. I would say passenger side mirror gets down when i put the reverse. But sound comes from behind the headlight switch. Does anyone know what is this? I am feeling like my front suspensions are auto leveling itself.

The car makes all sorts of sounds during startup and shutdown. It's normal.

The sound is from the brake booster pump pressurizing the brake fluid in the lines. The duration of the noise also changes with front brake pad wear/thickness. It's some sort of ABS test.
