Stupid question time...

Once i remove the EGR do I have to do anything about the electrical connection? will the ECU compensate for it not receiving a signal?

Just tape it up and tuck it away :-)

No problems with the EML ( Engine Management Light ) regarding the EGR connection mate, as said just insulate and forget...

done :o)

Trackdayrider, just be careful of the Jubilee clips mate the one on the left looks like it could have been a size or two smaller, cannot see 'tother one, but they cause small little pinches to the hoses and allow leaks when hot mate..

Yeah, cheers Lez, they were the smallest 2 I had in the garage. I'll get a couple of smaller ones at the weekend. I ran up to temp and all seemed good, not going any distance the rest of the week so shouldn't be a problem until I get some smaller ones

I "borrowed" these photos, but this is what EGR does:

I would like to see how this is driven and used though. I bet it never gets a good run out,

Oils can also play a part in carbon blockages ..

My two pence worth. Largely based on trying to think processes through logically, as opposed to experience - which I don't have much of in automotive engineering at this point. I'm deviating, so here it is: No one seems to contest the point of an EGR, that being to reduce emissions by making sure that unburnt particles - as described by Lez - are burnt. The cable throttle truck does not have a cooler fitted to the EGR. That got me thinking, WHY did they then fit a cooler to the FBW truck? Logic dictates - correct me if I am wrong - it was to cool the recirculated gases before they re enter the combustion chamber. This seems to me to be an act of admitting my Mitsi that it is not wise to recirculate hot exhaust gases without cooling them first. As I don't have a cooler on my truck I then had to think, was the EGR serving a useful purpose or, was it a risk? No one has mentioned EGR's without coolers being a risk, but if Mitsi felt the need to cool the gases from 2002 onwards, and my truck was not cooling said gases, would I really want to keep the EGR on board? This was also one reason for fitting the EGT gauge. If I could monitor my engine temps in real time then I could be sure I was safe and that they haven't gone up as a result of the removal. I have since proven at least one way of reducing EGT's by a decent amount, and so I see no benefit from having the EGR on board. Other than an attempt to clean up the emissions. As it passed it's last MOT no problem on emissions - it appears to not be essential in that regard anyway. Logic also dictates that it would be re injecting carbon from previous combustions. So again, a potential for long term issues? The cooler may be the major reason why people remove the EGR, but I think the more relevant point is; why was a cooler fitted in the first place? Answer that, and you might answer why you would want to remove the EGR.

EGR valve and coolers are fitted for emissions purposes only, reducing the NOX gasses and allowing a better TAIL PIPE emission. Remember the vehicles have to meet emission standards when new, EU standards at that. Same reason why manufacturers produce 1 litre cars and then big 5 litre cars say, same reason why Fiat and Ferrari are involved with each other, all to do with emissions.

Amanufacturer has to produce cars for certain regulations and cant vastly produce very high emissions cars without producing low emissions, New Ferrari say produce ABC emissions, Fiat Punto say produces A and the 500 twin air produces nothing ...

Emissions and standards!

Well as NFTS has said it has done 240k and by the looks of it hasn't been serviced so who knows what oil/diesel its been using.

hi can you tell me how old is a classic? what does FBW mean do i have a EGR to remove on my 2003 Warrior 2.5TD sorry to sound like a pratt cheers wolfy

yep your 03 has the egr thats well worth removing , especially on that year

That counts as a classic ;) I'm running an 04 Warrior, and the EGR was taken off a few months back. FBW means Fly By Wire, or even more expensive shit to fix when it all fgoes wrong

hot diesel and cold air - best way, within reason of course

First thing I did to my disco was test the emissions, remove the EGR then retest. No difference in the emissions, but definitely seemed better to drive

hi being as i am useless at anything car wise i will have to get someone to remove EGR and blank off for me i have not looked but perhaps it is done already cheers wolfy

Have a look at this:

How to :- Remove EGR Valve, Pre-FBW

or this

How to :- Remove EGR Valve & Cooler

Its quite easy

cheers nick h121 it looks easy so i might try if not some lucky sole can do it for me but firstly i will have to buy the blanking plates etc cheere wolfy

were you based wolfy, maybe one the guys close will help/do it

i live in Braunton near Barnstaple North Devon i know Krutly lives in Barnstaple but he is injured i believe? so i dont like to ask him cheers

opps sorry Krutly i missed your response so sorry i will get in touch cheers i will have to buy the plate first?
