>i recently installed a new by pass valve that i got from blaufrgnugen this is a bosch 030401450710a wich can be used on the aan engine also. my question is, this has three ends 1to the turbo intake 1to the turbo outlet and the other one were does it go,because my old bypass valve only had the 2 connecters to the big hoses, now this one has the little nipple on the diaphram wich i have no idea were it goes.

The small nipple connects to a hose which in turn connects to the
intake manifold. Without this hose, the valve will stay open, and you
won't get the correct boost pressure.
