Knocking noises around the board Aygo X

My friend's car from work. They only come on at idle and not always. The airflow has no influence on this. After pressing the gas lightly, the sound stops. It's not the sound of an engine.

Something sounds seriously wrong there. Have a Toyota dealer check it.  Ive not heard anything like that

Diesel engine? 😅

And then there's that hissing air conditioning feature when you step on the gas, something like a turbine ;). But I guess every aygo X has that.

Time: 16-20 sec.

Hissing aircon sound : mine has it too. Previous aygo had it. 

I am not worried with that.
