Hello,

I managed to get my VIDA working so now I can have a deeper look at my AC in cab noise.

I check the ECM-A/C pressure...

With the engine at idl (675rpm and outside temp 5 degree) my pressure vary between 715Kpa to 1015Kpa. When the pressure is above 800Kpa, it is possible to hear a hising noise inside the cab.

Does anyone know the pressure I should have ?

I recorded a video of the pressure going up and down with the engine at idl. Maybe this can help ?
