out in the car earlyer and it was running like a bag of shit!

The turbo(t2) was spooling up like a bastard at under 2000rpm?
Running rough on tick over and when driving when you put your foot down it seemed to bog down for a second and then slightly picked up again.
Did notice the dump valve( yes i know they're not good on cvh, but the missus likes it ) has been letting air escape rather then dumping it.

It was fine when last driven just come on over night.
Any idea's? Hoping just an air leak but any info would be welcomed

 

sort out the leaky valve first, and check the wastegate actuator is moving right

 

dump the dump valve and you will know very quickly wherein the problem lies

 

thank's for the reply's.
I took off dump valve and a bit of wd on the actuator arm from the turbo took it out and it's fixed

And got some sweet chatter going on now

Think the dump valve was to blame in the end
