    I have been looking on honest John and came across this

    "On some 2.2 I-CDTI TSB replacement of EGR valve led to big increase in fuel consumed."

    now I am getting around 35 to 37mpg which I am not best pleased with..
    on there real MPG calculator it is showing 94% of them are getting around 44mpg.

    is it possible that mine has had the TSB thing done (don't even know what that is).. if so how can I get it back to 40 plus.

    cheers
    chris

    Interesting, I have heard cleaning the EGR can help with fuel consumption but not sure what the TSB stands for?

    TSB = Technical Service Bulletin. This forum has lots of info of TSBs if you do a search.

    There are many reasons why your MPG might be down, so I wouldn't focus solely upon the EGR valve. Maybe that article was confusing the early Accord EGR valve (which was electrical) with the later vacuum-operated 'downgrade', which is far more prone to sticking open and causing problems.

    Not known of replacing EGR valves creating a negative impact on fuel consumption? I think it's just a load of bull myself. Many things effect MPG. EGR sticking will also create a performance issue which I assume you don't have? If your ok with the spanners it's worth whipping off the whole intake manifold and giving everything a good clean. You would be surprised at the build up of carbon

    image. image.

    This is with a head on the bench and intake manifold removed. See how thick the carbon is inside the ports of the head! You won't remove this just removing the EGR valve.
