    My FL1 just passed an ITV (Spanish MOT) with flying colours. It has an EGR bypass fitted and all the emissions were excellent.
    In addition to this, the Spanish are now connecting a yellow-coloured box into the OBDII connector and testing, or monitoring, with the engine running.
    I reckon the VW software scandle is respnsible, perhaps. Anyway, the ITV was extremely cautious and everything was checked & tested.
    The EGR wasn't an issue, though. Amen.

    The EGR probably won't actually operate in the scenario the MoT creates for a diesel. It only opens under load, fast revving won't load it. If the MoTer cannot see the mod (i.e. a simple plate in the line) or it's hidden under engine covers or the whole caboodle has been removed thus the MoTer won't actually know if it was meant to be there or not then there is not an issue with removing an EGR.

    EGR is about NOx reduction by reducing burn temps, however, as a side effect fuel burn increases - thus more pollutants, albeit less NOx at any given time, however overall combined it creates more NOx! You also need to consider the whole process of getting a vehicle moving, starting with the oil extraction, then refining then moving the fuel to petrol stations - if you take that all into account, you have to wonder what they were thinking when they thought burning more fuel (to extract, refine, transport and then propel the car) was a good idea.

    I had a friend who bought a new Case tractor in about 2009, he bought it to add to his existing tractors, one which included an earlier 2000's model of the same tractor - one of the major upgrades was the newest Euro standard engine. The same old tractor with the older diesel could do far more work on a tank of diesel than the new one, he reckoned the new one needed refuelling about twice as much as the old one - he took it back and said it was faulty - after some confusion they finally came back with the explanation that all the new engines did that as they were cleaner but were not as fuel efficient! He was not chuffed!

    That's the same for petrol or diesel engines. What comes out the back "might" be less polluting, but that comes at the expense of increased fuel consumption and so increased CO2 emissions.

    The problem is these people who dream up these rules, don't seem to have any technical knowledge in the area the rules apply.

    These are probably the same people that forced lawnmower manufacturers to fit auto chokes thereby making them hopelessly unreliable after the first year.
    I bought a lawnmower with a Briggs and Stratton engine which I know will be unreliable but also drinks petrol for fun.
    Give me back my old Honda engined lawnmower I bought 20 years ago any day.

    Probably. They're clueless muppets.
    I actually bought a battery powered lawnmower this year, which I've used in preference to my large petrol mower. The battery mower seems to cut well, even when the grass is 6" long. It's much lighter to use and much much quieter too, so I'm well pleased with it.

    I was going to do the same but I need a 20 inch cut and the battery ones were more expensive Now I wish I had as the amount of petrol I'm going through is making this one far too expensive

I've got a 2001 TD4 auto not been remaped and has 145000 miles on the clock, currently I'm getting around 32 mpg which i would say is better than Land Rover's offical figure considering I tend to do more urban driving, to and from work 4 miles each way on city roads with 7 sets of lights (usually all on red). I'm going to fill up my tank and do my usually runs and stuff then see if there is an change to the mpg... Pics are of the old EGR I've removed.

    Personally if I were you when you have time remove the manifold and give it a good clean out, just adding the bypass will help but it still remains what ever you saw in the old EGR is inside the manifold too, and the MAP sensor will most likely be gunked up at the point sensor takes it's reading, remove this and wipe it clean, do not poke anything into it, I cleaned four recently including the EGR ready for this weekends last meet of the season we have for our R40 MGZT V6 V8 1.8T etc

    I more than likely will if I get use of the In-laws drive and garage and as I have to do my work roadside atm as the tin tent is on the drive as well as making sure I have a couple of days where i don't need it, as some have said it's better to leave the manifold soaking to get the baked on crud.....

    Did you get the kit that has the large washer on a stick which supports the exhaust transfer pipe? The kits that don't have the supported washer are bad as the exhaust transfer pipe breaks off.

    Yes I did get the supported one, I did notice on some of the fleabay didn't have just had blanking discs... the seller was EGR-DELETE

    A good jet washer will deal with it in 45 minutes spray all the outlets even the very tiny one which the MAP sensor fits into, let it dry out for about an hour or get ii air blown out, refit the same day

    when I did the bypass on mine I did it in stages, bypass first then I cleaned out the inlet manifold at a later date with oven cleaner and a jet wash noticed an improvement after both :)
    I didn't believe how much **** pored out of the manifold like doing an oil change :confused:

    Can you recommend/link a specific manufacturer for an EGR kit? I'm looking at the moment but can't make my mind up as to which one to get, especially with the wide range of prices.

    I refitted the EGR on my 06 TD4 two weeks prior to the MOT as I didn't want to take the risk of it failing.
    I replaced the blank after it passed and the difference was obvious. Much more responsive with the blank.

    Evening All,
    did my bypass a little over a week ago and done some milage as well....
    Urban driving was about 32mpg now just over 33mpg so a little increase but the throttle response has sharpened up and also seems to drive a lot better.... have been driving like a hoonigan to get it to kick down to see how much crap is kicked out of the exhaust but must say seems to have cleared up..... now I also did a long run at the weekend yorkshire to surrey just ove 240 miles each way... did a steady 70 @ 2500 revs where possible and managed to get there and back using just under 49 ltrs.... so about 43mpg again up from 40mpg i managed last time....
