Shawn,
Back to an Audi?  Ah.... I get it... a masochist!   LOL

On the A/C issue, there is no low side port.  The procedure is evacuate and
fill with the correct amount, starting with 0.
I have no idea why Audi does this.... every other company gives us high and
low side ports for testing.  Supposedly the compressor itself might have a
plug which can be used as a low side (for testing only), but can't be used
for filling.
