Hi
Vehicle starts on the button no codes, but on acceleration heavy diesel knock coupled with black and white smoke at the rear. After 2500 rpm this seems to clear and engine rpm increases with full boost and no problems. Its sounds almost like a misfire with a diesel knock thrown in. Fuel filter new.
Wondered if this has pre-supply to filter head although has hand primer?
