Sounds like the best bet is to try the UV method and UV light with special goggles.

thank you, that sounds stops when AC is off. Maybe that is good, because leak is somehere ir engine bay.

Here in Lithuania mechanics uses UV method or fill nitrogen in to the system, sniffer tool is unheard-of :)

If you put in refrigerant, and then shut the engine off, and it still makes that noise, it would be a leaking condenser or expansion valve inside the dash there. We mechanics use a sniffer tool to smell refrigerant leaks there
