95 gti vr6, blue valve, normally closed.
Just looked at mine. The P/N for the rubber ring reads 054133459B, but I couldn't find a # on the blue solenoid itself. I then tried to find a diagram online, and wound up here:
So, it appears that the P/N for the blue piece is 058133517.

Arrow towards intake manifold, most definitely normally closed.
I dont think they would make any of them normally open. With it "off" it would fill the intake with fuel vapor. The charcoal canister is there to deal with the vapor in that situation.

Yes, normally closed = no flow with no voltage.
What is interestingnis that in the 12v self study that valve is listed as normally open as well. Must have been a running change at some point but its definitely pre obd2 change.
