Lost boost on my P1 but the car seems to be running fine just no turbo working or very little. What could this be? THANKS

 

running fine ? as in what ?

it wouldn't be running fine if you lost boost


try looking for any split pipes or pipes that have shifted around the intercooler, dump-valve, inlet , turbo areas

might have a slight split in one of them

 

if the turbo was f**ked would it still run ok

 

Check the pin on the actuator rod

 

It just feels like a none turbo car lost loads of power

 

good call beal . . if the pins come out then it will only run actuator boost which is not alot
0.5 ish iirc

have you got a boost gauge ? what's it reading ?

 

bttt

 

no boost gauge just no its not right

 

do i need to remove the gaurd on the turbo to see the pin?

 

If your not mechanically minded take it to JDM performance in Derby just off pentagon island. They will diagnose the problem.

 

It happened to me on my RS turbo

 

bttt

 

checked the pin on the actuator rod and that seems to look fine any other ideas

 

agree with dazza, it prob your boost solenoid. check connections on that. happened to me

 

were abouts is it? CHEERS

 

The Boost Control Solenois is on the drivers side inner wing just in front of the suspension turret, under the alarm, you will see the pipe coming from the T-piece on the turbo (bwteen the compressor out and the actuator) to the BCS and from the BCS to the air intake pipe.

You really need to get a boost guage, even a £15 cheapy is very useful for diagnosis, I just run the pipe through the door and stick it to the dash with bluetack, then remove it when I've finished the checking!

Its not unknown for the BOV to leak (back into the intake), you can block this quite easily on the 99/00MY's (inc P1) by cutting a piece of card to drop in between the bolts, so just loosen the two mounting bolts to the intercooler, slip the card in and tighten it back up.
