hi having probs with my car, just finished building my car other day and took it to mot station. on the way i found that as soon as my gauge hits 0 psi the needle flickers up n down rapidly, and just wont boost. i can hear the turbo winding up but it just holds back and judders?
anybody got anyideas as to what this could be?

cheers

 

Has it got a bleed valve on it? If so unlock it and turn it all the way down and adjust again. I had a similar problem after the car was left for a while. Jamie

 

where abouts is the bleed valve mate? im not sure

 

Hey bud look at turbo and then find the actuator and follow the vaccum pipe and you should find a small device which the pipe goes in one side and out the other. It should have an knob which you can use to adjust the boost the car will run. You should have to unlock it with a small Allen key. If this device is there turn all the way down. If it's not there check the pipe hasn't come off at the other end. If all is good you prob have an actuator issue (the bit what allows the car to build pressure) Jamie

 

Ive sorted it now mate I didnt tighten the boost hose enough so its my fault lol
