I actually helped a firend out with a similar install (B6 IC) a few weeks ago and we ran into the same thing. Although he hasn't started it yet, he has done the same thing.. I ran it by one of the local shops and he claimed they do the same thiing. The valve is like a dampening valved, or at least that is what he told me. From what I have seen, it looks to be an electronic air bypass (read that in one of the manuals).
