[V6-12v] V6-12v Digest, Vol 75, Issue 1

[Austin Franklin]

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.
