Hi Eric,
The only sensor I know of is the low side pressure "switch", and I believe
it really only is an on/off value. IOW, it's either above a set pressure
and the "switch" is on, or it is below a set pressure, and the "switch" is
off. I could probably read at least that with VAGCOM I'd guess/hope.
Best Regards,
Austin

Maybe someone else knows if the A/C sensor values are readable through the
VAGCOM. If anything this will give you digital values. I can't imagine
they have analog pressure information of the high and low side.

I also have a VAGCOM if that can be made of any use in debugging this.
I
haven't checked yet.
