    I have purchased a egr boost gauge removal blanking bypass kit. It came with no fitting instructions.
    the kit contains new housing to replace the egr valve/stop cap/blanking plate //two metal disks.

    the new housing has a small tube welded to its side. I assume this can be used for a boost gauge.
    blanking plate assume for exhaust manifold
    stop cap ?
    metal disks?
    If this kit is to remove the erg , what do I do as the stainles steel pipe from the old erg has a cooling pipe and bleed nipple attached to it. ?

    looked on web but no luck

    These kits are all slightly different.
    Usually the metal disc fits in the old stainless pipe to blank it off.
    Yes you can put a boost gauge on the small pipe bit.
    Don't forget to block the vacuum hose as well.

    kit I have must remove all traces of it, think I will change it for the type that leaves most in situ.

    Won't you need to keep it on for the new MOT??

    Isn't the small pipe on the body just somewhere to fix the vacuum pipe to in order to blank it?

    I will have to look up what the new mot requires but I thought they only checked nox gases which the erg does not effect

    Any modifications/removal to emissions related devices, this includes DPF'S and EGR's is now a major fail.

    above is part of the new MOT from may 2018
    will put my erg kit on ebay !!!

    EGR is all to do with NOx

    All vehicles requiring an MOT are currently tested for CO2 and hydrocarbons, not NOX. Visual checks for excessive smoke are also carried out, although it seems to be at the tester's discretion as to what constitutes "excessive". The official MOT manual suggests that sufficient smoke that could obscure the view of road users behind you would be a fail.

    As for NOX, this is a by-product of the diesel combustion process, mainly due to the higher combustion temperature of diesels. The EGR system bleeds a portion of the exhaust gasses back into the inlet which has the effect of lowering the combustion temperature, and hence the NOX emissions.

    NOX is a well known contributor to, and direct cause of, respiratory problems and this is why legislation was introduced to control how much is emitted by diesel vehicles, hence the development of EGR systems. However, EGR systems affect engine performance and anyone who's ever taken off an EGR valve and inlet manifold to clean them out will see how much black sticky gunk ends up clogging them up. This means more maintenance which means more running costs. It's no wonder people want to bypass them.

    And of course the government realise this so in future the MOT will be tougher around emissions control.

    Of course, there will be ways of tampering with them that leave them still looking standard, and your local MOT tester will still have his own interpretation of the guidelines so it may not be the end of diesels as we know them yet.

    Yep. It'll be a major fail in the new MOT.

    The EGR is only there to reduce NOX emissions. Removal will increase NOX and also fail the new MOT.

    Additionally unless the EGR bypass supports the exhaust transfer pipe, the pipe will break off very quickly, which is a major headache.

    Many thanks all to this old thread (oops I typed threat, which could also fit in well, but) ,
    but still new to my old enquiring mind.
    My old girl has done 180.000 plus miles, runs very well, but fancy trying a cheap EGR replacement for use in "Non MOT days"
    this will also give me some time later to de muck the pipes needed along with the EGR replacement just before its MOT.
    I`m finding I get a slight hesitation from standstill so the the thought of trying the BYPASS jobby.
    For`s and Against`s
    Just asking coz I can, but thanks anyway.
    Ian.
