Mechanical whirring when going over speed bumps?

Hi folks,

For a while now I've noticed a noise when going over speedbumps from what sounds like the front end of my Model 3 Performance.

It doesn't sound like a problematic noise, but more like a motor doing something. I just wondered if anyone else had heard it and if anyone knew what it was?

The speedbumps are the large tabletop ones that you drive on one end and off the other end, and there's a quick motor whirring noise at the front end when I go up and down them (and sometimes at other points as well). I don't really notice the sound when the radio is on, but if the car is doing its thing where it decides it can't get a network connection for Spotify then I notice it easily.

I'm thinking it could be the motor that opens and closes the front grille slats? Or motors in the headlights? (Albeit, headlights are off when this happens.)

Or maybe something else?

My car is a late 2019 build.
