What is this hissing sound at idle?

Does anyone know what might be causing this loud hissing sound at idle? It seems the loudest just behind the front-left tire. I don't hear it when looking around the engine bay.

Could well be the fuel burning heater, it's situated on that side.

This is a petrol V8...I was thinking the fuel burning heater was only for diesel? 2021 P525 | Eiger Gray
