    Default EGR workaround..

    Ive cleaned the egr valve about 1 month ago, Today ive cleaned and drilled the egr to get the piston out, That was spotless...
    Brand new gaskets and a full clean...Its still juddering..

    If I unplug the electric connector will that keep the egr closed..yes?
    It will bring the idiot light on the dash on..Yes?
    Will the car still judder if the egr is fubar and electric unplugged or will I be able to tell the difference and then once and fore all dismiss the egr and look for something else..
    After a few starts of the car the idiot light will go out naturally..Yes?

    Ive been to A+E today because ive sliced my thumb on one of the thin gaskets and now im getting peed off...Main dealers charged nearly £3 for two gaskets........Tosh

    If your unplugging the egr, do it before you start the engine... yes it does bring up the mil (spanner) but should run fine with no judder.
    have a good look around the vac tubes etc... any splits could also cause a judder as could a failing swirl pot.

    If the valve is jamming open then it may not close properly so may not cure the problem. Take the valve off make sure it is closed and connect up but don't plug in the electrical connection.

    Ohh trust me the valves are closed..I put allot of brake cleaner on top of the valves and they didn't leak one drop....
    Cheers guys I will give it a go and let you know...
    After searching on here its about 20 fresh ignition starts for the spanner to go out, or am I reading it wrong...
    Once again THANKYOU....
    I cant see why people go to the main dealers for their technician's when there's more people on here willing to help with their own experience's which is more relevant than ALL the technician's in the whole of vauxhall..

    Yes, after 20 it will clear, but if its still disconnected it will stay on.

    Agree with Gaz, disconnecting the EGR electrically will only stop it operating, and will not guarantee that its sealed shut, which isn't that easy to ensure.

    Cheers m8, I know mine didn't seal/close freely as it took a blanking plate to find that out.

    The EGR Valve on my dads CDTI 150 has been unplugged for about 6 weeks now and the car is running the best it ever has. EML is on but who cares, car runs well as it is.

    Hopefully soon it will be blanked off and MAPed out so the EGR is redundant and the EML will be off too.

    Well some good news and some bad...
    With the EGR unplugged the car does run smoother, Ticks over smoother..
    BUT it still judders going up hill, not as violently tho'..
    So I assume that the EGR is fubar simply because there is a marked improvement..
    The vac pipes are still a suspect..
    Im going to blank it off this week just to make sure the valves were seated...
    As always I will let you know the results...Ohh and thanks to all...Tosh
