i'd check all your hoses are connect'd properly? have you had it for a drive? take it there's a lack of power?

Do you run a maf sensor or have you deleted it?

If you still have it a boost leak would make the car overfuel like crazy. You would know from the smell, jerky response and plumes of black smoke when you booted it.

If you don't have any of these symptoms I would make sure the circlip on your actuator arm hasn't come off. It's a very common problem but thankfully a cheap and easy fix.

yes still have the maf no smoke or anything all hoses seem to be on and tight

Mine done this a while back. On second it was working fine and next it had no boost at all. Can you hear it spooling up or what? Checked the wee cir clip that holds the actuator arm? My problem turned out to be that my decat flexi joint up-pipe had giving up and fed itself to my turbo!

That can happen too but isn't as easy to diagnose, check the simple stuff first.

just been having a look round all the hoses are on

circlip is on actuator bar is moving and when car is runnung and u push the actuator u hear a slight clicking then when u push it right back it goes away

only thing i can think that i have done different is i put some forte advanced formula gas treatment in with my fuel could this be causing it as i only done this yesterday
