Hi, I just got my wrx back from the garage but there doesn't seem to be any boost, I checked the lines for suction and there seems to be suction from the top of the inlet manifold but nothing from the air intake pipe to the boost solenoid, can anyone help me please?

 

start with what work was carried out at the garage and go from there. Take it back if its something theyve done or caused . If its going to cost cos of work they did and you didnt know , then why should you pay for repair. Let us know how u get on
