Hi i'm still having problems with my 1.9cdti 150 keeps juddering. I have just recleaned the EGR valve and boost sensor. I also did the air box mod while i was at it.
Went to start the car after and it wouldn't start. i did leave to pipe from the air box off and the one from the inlet manifold. Once i put these back on it stared but was running lumpy (could of been the carb cleaner) then it stared to run a bit better but still juddery.
So i removed the injector plugs to see it that was the cause but no so i the disconected the boost valve, no change so i then disconected the EGR and it cured the problem.
My questions are:
1. Will running the car with the EGR Valve disconnected cause and damage to the engine?
2. Where can i get a blanking plate for the EGR and what fiat gasket is it that everyone is going on about??
