Whilst I don't disagree with anything else that the above is snipped from, it's worth noting that what an EGR does is undetectable by the current MOT test. It's sole purpose is to reduce NOX, which isn't tested for, so using good emissions results as justification for removing an EGR is a flawed argument.

That's interesting Steve, do you have any details ? Is it a forum deal for replanting ? Mo The Land Rover 90 - Many are called, few are chosen. 50 Shades of Pennine Grey |

5 gas analysers can measure the Nox emissions. He could have done his own tests not just an MOT test. |

one of my friends does some work for a climate change lobby...
When we discussed how Defenders last so long (there was a claim about 85% of Defenders/Series ever built are still "working" somewhere), compared to a Kia/Renault/Nissan etc, he did some thinking and planning, and decided that Defenders could have a lower footprint than "disposable" cars, whilst we may have lower MPG, the lifecycle of the product is better. ... And almost certainly a lower footprint than a family dog! American dogs alone are responsible for 10 million tons of waste a year. http://www.salon.com/2014/11/20/the_surpri...t_partner/ medium-size dog has a footprint of 2.1 acres http://abcnews.go.com/Technology/pet-dogs-...id=9402234 They say an average Collie eats 164kg of meat and 95kg of cereals a year, giving it a high impact on the planet. A medium-sized dog has the same impact as a Toyota Land Cruiser driven 6,000 miles a year http://www.telegraph.co.uk/news/earth/envi...laims.html Maybe Defenders are not so bad after all...

He could have done, but he didn't. The circumstances have been discussed before. Darren 110 USW BUILD THREAD - EXPEDITION TRAILER - 200tdi 90 BUILD THREAD - SANKEY TRAILER - IG@landroveranorak "You came in that thing? You're braver than I thought!" - Princess Leia |

The first 40k LR had a CO2 offset initiative covered in purchase price, I believe this went towards various projects involved with CO2 off setting with tree planting initiatives etc. Also a lot of Wildlife trusts use Defenders which of course helps the causes with the natural environment, inc Enviroment Agency etc It is also indeed true that Defenders have typically at lease double the lifespan of many disposable cars. So you are talking various metals production inc CO2 produced in mining in particular for mining precious metals The best recycling method imho is longest lifespan, and to not buy to replace. This debate could go one forever.  WeWillWin🇬🇧🇺🇸

Is there a consensus best method for actually doing the job?
I've seen everything from the £30 part with blanking plate, some with multiple plates and full removals including replacing a pipe with the LHD version but can't really find much on the pros and cons of each? |

^ DDP, I would go to a professional mapping company (BAS/Alive, etc)... and have it properly deleted as part of a remap.
Not sure I would just blank it.

sorry not read all of the posts and only the heading of the article and whole heartedly disagree.
I'm not the only one to have suggested a 10% increase in economy following the removal of the egr as part of a re-map process. Granted the 10% might be entirely down to the remap? I'm of the opinion that by removing the egr this have given the biggest fuel saving. Not sure I can find it but there was an article suggesting diesel engines can run upto 20, 30 or % more efficiently without the egr. Clearly that doesn't exactly correlate back to mpg. 
I'm happy that a 10% improvement in mpg is a good offset against the downsides to having the egr operational.  |

The cumulative effect of both the shut EGR and higher fuelling efficiency does indeed help a lot. When I had the faulty egr. (Even though there was no signs to tell) there was a markedly district drop in mpg. Increase after the map and increase slightly again with the additive.
Now I run both I’d never go back, smooth efficient and powerful. Just what the Defender needs to keep up well with standard traffic. WeWillWin🇬🇧🇺🇸 ⛽️🛢️⚙️🧰💪 |

^^^ FFS Custom, did you not see what I wrote in the OP? I clearly state "Unless some evidence arrives to dramatically change this opinion, the EGR stays."

Yes, I did see it. I would suggest you keep it if you feel so strongly.
It begs the question as you appear to be so certain of the EGR’s complexities as to why you’ve asked the question in the first place! When you mention in your last sentence “Let the debate begin  “
Suggests in its self that you know full well there will be no full agreement on here regarding this, and then you suggest “muddying the water”. Make your decision and get on with life, it’s not difficult. It’s not a life changing event. Seems a bit like to me asking what colour should I get my Defender in or do you guys like roof racks or not. Etc etc. Personal decision, easy enough to make and reversible. Over and out..

Oh Custom, I don't feel strongly either way, hence the brain flip-flopping between the two options. Ultimately I do not want to be an evil polluter of our precious air, but at the same time I do think there is a lot of guff spouted by manufacturers, a lot of EU/Govt tests and controls that have no real-life bearing or validity, a lot of opinions that are entirely unfounded, and a lot of fads.
I think this forum is certainly one of the most honest and experienced and I think if general consensus (through experience/usage) leans one way or t'other, it probably has more validty than a factory or laboratory controlled test. So, higher MPG, lower soot build up, greater engine efficiency (along with a map), less fuel burned etc etc, does make me wonder whether EGR blanking does have some benefit without unduly polluting the environment. Completely contrary to the link in my OP. Oh mon dieu, zut alors, oh la vache, etc etc
As I am looking to have the very best engine possible (power/torque/cleanliness/noise/daily usability/reliability/mileage etc), I'm leaning to blanking now.... Monsieur Le Grenadier
