Hi Dangerous Bryan

Many thanks for the reply, I will check the pipe when next home but the one you mention is that the one that goes from the EGR valve along the front of the engine, and looks like it becomes a metal pipe, there is another one that people have mentioned that is one for splitting that is from the under side of the turbo drops down between the g/box and Battery or somewhere in that location, AA man says codes were 404 and he thinks a poss 409 circuit control not sure what to look for on that one when engine is running smoke is blue and smells of unburnt fuel

regards

Rammer
