help wierd problem

[krisbutler02]

right i have a boost problem

in the morning or the car is cold the sai pump runs then turns off which would normally give u boost after its done what its doing

but no i get no boost atall how ever long i drive it and the actuator is movable in and out with no resistance and can hear air moving somewhere (not a boost leak) all vac hoses are intact

then i pull the pipe of the n112 valve (tssssssss) then the acctuator goes stiff and start car up and i have boost

i have done the n249 bypass and its been done for months

any ideas people , can i bypass the n112 without removing the sai ?

I managed to block off the other part of the n112 valve by mistake before and had no boost no dump noise but still sounded the same. With turbo spool etc. Could be nackered n112 or blocked/kink in pipe maybe...
