    My egr is blanked off but has anyone removed all traces. Pipes, sensors etc.... ? Is it possible and what was the result.

    Google begs to differ. If it's blocked off and passes the mot then surely removal of the whole system would be fine?

    Gotta check the MOT manual mate, can't trust the first thing that pops up on google.

    Right, but the sentence you've cut out of your quote between the sub-heading and the description of the check says:

    Last I checked diesel cars don't get the full catalyst emissions test.

    I've even put the correct header number in, at least bother to read down far enough.

    Haha, fair enough… I clearly have read the wrong part of the manual so my apologies for that.

    What’s with the swearing though…? Really...?

    I read this as only check parts that are visible and identifiable. If all the egr bits are removed then surely are no longer checked under the mot?

    Part of it will be down to what can / cannot be seen on a visual inspection and part of it will be down to how familiar the tester is with the particular vehicle / engine.

    On my CR engine the EGR pipe is clearly visible with the engine cover on so if the tester knows it's supposed to be there and isn't then they should be failing that.

    Don't forget there's a port on the exhaust manifold that will need blanking off with with the EGR circuit completely removed and there's no way to do that without it being obvious there's a blanking plate that's been put there. This would be visible from an inspection from below, as would the absence of the EGR cooler if you removed that too.

    No, like the manual says if it's obviously missing then it's a straight fail.

    The MOT testers aren't idiots, they'll know what the EGR looks like and what an EGR delete pipe looks like.
    It's front and centre on the engine too so it's completely obvious.
