I think is the same as the V70, behind right headlight just forward of the alternator pulley on the low pressure hard line.

You won’t have a high side fill port unless you have the rare and coveted heated rear third seat.

Yea no high port -- how are you supposed to check the high side pressure? I don't understand their non-standard intended routine for filling & purging.

You can read it off with software or a high end scanner. If you don't have OBD, you can read the resistance of the high pressure valve and map it to pressure. I think this data is in the VRD somewhere.

The best way to fill any AC is by evacuating and filling by weight, anyway.
