    Default Egr / swirl valve headache

    Egr / swirl valve headache!!


    SIGNUM 2006 1.9CDTI 150PS AUTO.



    Can someone help with this, have had all the usual probs as listed below;

    poor power under 2500 rpm

    no spanner light

    swirl valve arm attached

    lumpy tickover until i rev it a bit.

    cleaned EGR valve and cleared 2 EGR holes in inlet manifold, boost sensor.

    Power restored for about 2 days then back to no power. I have checked the valve and sensor and all is clear, checked the swirl valve arm and that is still on although very loose and i have noticed that when the engine is running the fourth swirl valve top is slightly moving within the arm cup.


    back to square one help.

    cheers doug

    DOug, have you done the 'full' clean of the EGR, i.e. drifted out the solenoid and cleaned it?

    Do these faults only affect the 16v 150 engine?

    has anyone ever challenged vauxhall in the small claim court for the whole EGR/swirl valve/manifold fiasco, I think I will chance the 40 or 50 quid it costs and see what happens, I think I have a case under the 'not fit for purpose' rule

    dougb it sounds very similar to the problem i had ,no power under 2500 revs rough tick over but no warning lights, done a full egr clean power back for a few days power starts to fade away again, another egr clean power back again and so on .
    anyhow done a bit of research on this web site and came to the conclusion you can clean the egr valve dozens of times ,but the problem will always come back .In short new egr valve problem gone...
