    P0400 Egr Cleaned_ No Good Replacement ?? 2L DTI

    I have had a problem for a few weeks now with my 2001 2L DTI, p0400 code present so we took the egr valve off and cleaned it, still the same

    Had it looked at again today and was told we could try cleaning the "butterfly flaps on the inlet manifold"

    I have searched through loads of old posts about the p0400, and I know just cleaning it only seems to be a temporary measure,

    Is it worth just getting a new egr - delphi ones, instead of wasting time cleaning bits when it still isnt working

    Thanks

    i'd clean the inlet as thats a free fix if it works but you may be better off buying a replacement egr if that doesnt work, dont buy anything but the genuine part as the cheap copies tend to die within weeks

    From what I remember the is a 'Vauxhall fix' for this that's quoted on Autodata.

    I think there is a Grey/black wire that needs to be cut on the EGR plug and insulated.
    The truth is always the truth even if you haven't realised it yet...

    2001 should have the vacuum EGR, not the electric one so that probably won't work.

    I've read quite a few posts about this and looked up the Y20DTH EGR system with TIS 2000 - I figured that the idea must have been to cut one of the wires to the EGR solenoid valve over by the battery thereby rendering the vacuum operated EGR valve on the intake manifold inoperative. Does anyone know if that is correct?

    I have seen the EGR solenoid valve for sale on a few websites where they call it the "EGR valve"... so is that where the confusion lies?

    Yep its the vacuuum egr I have got, Iv cleaned the inlet so its running ok at the moment but think it will only be a temp fix, your right about the vauxhall egr "update" it is to cut through the grey wire, but iv not got one, so will just have to see how it goes,
    Thanks

    that's interesting - so TIS 2000 information is wrong yet again.

    As I mentioned above it shows the EGR valve itself mounted on the intake manifold as well as the EGR solenoid valve (with bothe cauum tubes and wiring harness) mounted over by the battery.

    Oh well...

    I know its confusing you get conflicting information from one website to another, and round here the mechanics have all got a different answers as well
