Been looking over the site regarding the pesky EGR phenomenon and have found a fair bit of useful comment on it. Strangely though if you punch "EGR" into search (for posts or threads) you get a puzzling result "Sorry - no matches. Please try some different terms." Then if you try, say "EGR MOT fail" you will get a lot of interesting but not directly relevant comments mainly on various MOT failures but rarely directly relevant to what I'm looking for. I guess this is a very roundabout way of me saying sorry for bringing the EGR thing up again, I'm not being lazy, I've really tried. So here goes.
Will blanking off the EGR on my 1996 Discovery 300tdi, if spotted by the tester somehow, be an MOT fail? You see I'm considering blanking it off and replacing the top hose as well to a straight through one, which would be rather obvious to the partially trained eye.
My thinking (possibly flawed) is that not only does the EGR put waste gasses into the engine, it also provides a thermal route from the hot exhaust pipe to the cool intake hose, kind of making all the fine work done by the intercooler a bit less effective. It also causes a rougher ride for the air-flow.
If the pipework should be present for an MOT, then why not just put a ballbearing in the vacuum hose before the EGR so it doesn't activate it and save the bother of fitting the blanking plate at all?
Any thoughts folks? - or can you post some direct links for me as I'm sure I'm going over old ground, but then again, isn't that what Land rovers are all about....boom boom.
