    Honestly, you're missing out! It's a standard mod I'll do every car I have from now on.

    But a) does it affect emissions and b) what happens with the pipe from the turbo? Do those gases just disperse straight into the air?

    a) No, not to any measure worth worrying about and it certainly won't affect your MOT / legality.

    b) Nothing happens - I don't quite know what you mean, there. It's just like permanently having the valve closed which it is some of the time by design.

    Edit: To be fair, one issue you MAY have is the engine management light coming on. I guess that can be a deal killer for some people - I personally didn't have the issue, and often you can just get the code reset. Or live with it!

    Ok, so forgive the cruddy paint drawing. The red circle shows the intake, the pink circle shows the egr valve strapped to the side of the intake, and the yellow circle shows what I figure to be the pipe from the engine (correct me where I'm wrong please). So I understand about capping the intake where the green line is, and removing the egr valve, but then this will leave the pipe highlighted in yellow unconnected and open.

    1) What is this pipe (seems to connect to the block somewhere)
    2) Does it also need capping? Disconnecting?

    Is the other pipe the vacuum pipe for the egr?

    Well, excuse my ignorance as I'm just learning, but I thought it would be the pipe from the engine to feed the exhaust gases back round into the intake. EGR = Exhaust Gas Recirculation.

    Or have I got the complete wrong end of the stick?

    Is this how you would cap off an EGR valve?

    Don't worry yourself about removing the EGR completely that's unnecessary. All you have to do is cap the pipe leading to the intake - there should be a gasket where the EGR input meets the intake system - this is where you place a steel blanking plate. That is it. The EGR is still [technically] functional and shouldn't cause any issues with engine management - if you remove it you're opening a can of worms, unless you know how to dock the EGR circuit at the ECU.

    This is the EGR valve from my motor (not mine exactly, but how mine looks):

    gasket material-largo_egrv.jpg

    The backside of this photo is what connects to the intake, but I haven't had it off to see if there are 1 or 2 holes there. The side you can see, with the threaded hole is connected to a pipe of a similar width (solid metal pipe) which from memory runs back to the block or somewhere. Can anybody help me clarify what this hole (the one you can see) is for, and if capping it should be as simple as the video I posted above?

    I think you need to follow the EGR system right around - it may just appear to be from the block, but may be attached to the manifold rather close to the engine, and out of sight. I'm just watching the video bud.

    *Edit:
    the video is correct - the part of your EGR valve that isn't visible on that pic - the one with the two holes - create a solid gasket as shown in the vid and place between the EGR valve and intake pipe.

    Thanks for helping, but please stick with me while I try and get over my confusion. Can you help with:

    1) the gold nubbin at the right of the pic has a rubbery small pipe attached to it - what is this?
    2) The other side of my EGR (that you can't see in the pic), will that have 2 holes as in the video, or 1?
    3) The large pipe hole you can see - what is this for?

    I understand the theory behind the EGR valve, but applying it to my particular model is difficult as it seems different to other more common valves. Can you explain how it works in relation to my model shown above, as an example (but obviously this is not correct, just trying to show how I need to understand it):

    1) The little fairies come from your exhaust through the large metal pipe and into the EGR valve through the front hole in the picture
    2) Pixies in the valve decide when to open and close the valve
    3) When open, the fairies flow through into the other side of the valve (which we can't see) and back into the intake
    4) The rubber pipe is just there for show
    5) Capping it will just constantly keep a few fairies in the pipe, but they will not be able to get further, nor will they leak out, not will it build up pressure and make the coke can go pop

    This is the sort of thing that helps me understand, so if you could do that I would be most grateful.

    And one last question (for now) - is the EGR valve similar in principle to a PCV valve?

    EDIT: And another question. How do I make a coke can the right size to fit if I don't take my EGR valve off?
