Hi guys,

was trying to see which one is which port yesterday on the 1999 quattro 2.8L.
Saw both lines but they are not identical and couldn't find a which one is high which one is low port to recharge ac.

Does anyone have a picture of engine area to show me which one is which??
And what kind of freon do I need to recharge with??

Thanks in advance.

 

The recharge fitting only fits on the low port. Just do it that way.
