    EGR's don't last forever though - regardless of how much they are cleaned.

    But Soulman is spot on with the boost sensor.

    Just a guess, but could it be the 3rd injector faulty wiring?!

    its just in the garage now, they have replaced the EGR valve and that has stopped the car and spanner coming up but still some juddering, they have tested the injectors and there is a slight iregularity on them but they are doing further tests tomorrow so fingers crossed ! will get them to clean the boost valve
