Update on problems with swedish Q4
Finally!!!!, we( A.Möller & me) have located the problem.
It seems as the Pierburg(sp?)-valve is broken.
I've disconnected it(electrical) and I still have 0.6 Bar in turbopressure. As I've just found out from the boys in the EVO-forum, the groundpressure is 0.6 bar.
Since I've tested 2 different chips,
(Thanx Maxiboost), and never got a higher pressure than 0.6, my car must have been on groundpressure for as long as I've had it.....
How much is a new valve??? anybody know??
Can I repair the old one or modify it???
