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 david |

Is T4 saying there's a egr fault after looking at the injector balance figures?
If it is then it's a false fault, just one of the many anomalies you'll find Russ

hi bigruss
yes but the EGR is not opening there is voltage going to the solenoid the brown/grey wire from the solenoid to the ECU is ok now if I am correct from the ECU it goes to the speed sensor I will check this next now the way I tested the solenoid was I took voltage to the solenoid then to earth started the engine and earthed the solenoid the EGR opened so there is either a fault with the wiring or there is a faulty speed sensor david |
