The valve that you replaced is not the BPV valve.
Actually I might have the lingo wrong myself.
Saab calls the valve Boost pressure control valve which would short to BPCV.
The valve you replaced with hyperboost is called charge air bypass valve and what I usually call turbo bypass valve.
The BPCV is a black valve with an electric harness and three hoses going to it. It controls the turbo boost.
No, I don't know what that missing part is. I can't figure it out from your description. It is a cup shaped plug that sits in the front left side of cylinder head. But if that one would be missing you would have oil coming out that hole.
