Mike you should have rung me mate, there should be 2 washers per banjo bolt and you should be able to push the valve up by hand. Sounds like it may be faulty mate. Do you want me to send another out, have one here, just tested it and it works fine. let me know or ring me tomorrow
Sounds like you've got the boost control solenoid the wrong way around.
First thing to do is just plumb the bottom directly to the turbo. This should give you 1 bar.
Try that then i'l tell you which ports you need to connect up on the AVCR's solenoid. It isn't the same as using an actuator.
