Hi to all
t4 says there is a egr fault and i have taken the solenoid off and you can blow through it and if i am correct the solenoid should open when the ecu sends a signal but i tested mine and it is open all the time so i think this is the fault i put a continuity tester between the two pins and there is a circit there i but 12v to one pin then the other to earth and you can feel the solenoid enegizing but i think the valve is stuck in the open position
