i am going to blank it off as i dont think its working anyway, its really thick with crud and the haynes says to remove turbo, cat and exhaust manifold just to get the inlet manifold off to clean it, not a job i fancy doing laying on my back under the car !! hence get rid of the egr altogether. I have a tin of egr cleaner on its way to help clean the inlet manifold.
The car runs rough almost like its missing, also has a knock/tap, starts fine but smokes a lot (whiteish smoke which smells of diesel) undoing the injector unions one by one makes no diffrence.
I have had the injectors out and they do atomize, also checked tappet shim gaps. tried another map sensor and crank sensor.
One odd thing is i take the intercooler to inlet manifold pipe off and place my hand oner the inlet to restrict airflow and the knocking reduces/clears.
Engine light is on but cant afford to take it to ford.
