Default Weird sound behind back left tire / gas cap

This morning when I went to the garage and approached my car, there was this strange sound coming form the back left quarter panel. Behind the gas cap or behind the wheel.
It was a whirring or electrical soft clicking sound. Constant.

I thought I was hearing things. I walked around the garage... Verified thats where it was coming from.

I started the car, then turned if back off and went out and the sound was gone.

Any ideas?

That’s pretty normal, that is the EVAP checking for leaks. It does that every day, five hours after you park the car.
