Hi trevor. yes I have checked that just now as the pipe was already off before I did the egr valve..the pipe goes straight up to the air intake pipe. is that the air flow meter on that pipe or is it down below where the egr valve is at the bottom of that pipe? Going to dig a new fuel filter out tomorrow and put that on as I have never changed it. My other x type diesel ticks over lower than this one when the car comes to a stop which I find out...its almost as if a choke is on slightly...anyway besides the fuel filter im thinking of trying the air flow meter.
