There is an auxiliary circulation pump inside the left front wing, firewall side, which pumps the residual heat from the engine cooling system through the cabin heather core over a given time, only with key inserted in the ignition switch. The aim is to enjoy the passenger(s) with a few minutes of heat while the driver is outside the car, and the engine is disabled. That thing can cause quite a lot of noise, I would check that one day.

Thank you to belgium. I was thinking about that. Just what makes we wonder, noise comes even without touching the "Rest " Button during driving.

I checked this area. The "rest" Button works. I hear the pump running without noise.

I used my new Diagnostic Tool and there is a code related to airmatic . Could it be possible that the terrible noise comes from there?!
