update on this is its going to a diesel specialist on wednesday, a friend of mine he says he will put it on his computer to look for fault codes, when he took it for a spin he thought it could be a injector issue, as when the turbo went i was doing 60 mph then shaft snapped this would of also thrown loads of oil into the chambers so could of got a dodgy injector, hes put me some additive in the diesel to clean all the injectors then told me to go and blast it, but dident make any differance, the thing is it runs perfect just flat as a pancake feels like n/a diesel
