Hello,

I have have just replaced a leaking pipe from the A/C system in my 2003 1.9 TDI because the system got empty and it was also leaking oil. The filter drier is also replaced. I got filled up again at the garage recently and it is working fine but every time the A/C is on I hear the hissing sound, like it has not enough gas in in. But it has just been filled with 700g gass (single evaporator). I'm pretty sure it's not leaking again.

Does anyone have an idea what could cause this. Is 700g not enough? Because that's what the manual says

Thanks :)
