So I just replaced Cap again. Had the 04 before. Still condensation
So it hit me how to isolate the parts using sandwich bags and clear plastic wrap.
It's hard to see in the picture but after driving around at operating temps, Only the bag around the Purge valve shows condensation.
Now what to do. My knee jerk reaction is to order a new Purge valve.
I thought about just O rings but not sure they can be ordered separately
German purge valve $38, Porsche $86.

Is the "German brand" a factory tank? If not, stop messing around and get one. We have never had any luck with aftermarket tanks.
