hi ive got a discovery 2.5 tdi 300 and someone has told me to take off the exhaust gas valve and it will run better is this true and ruffly how much will it cost to take it off cheers

yes it is true, you'll get more power and better mpg, we normally just disconnect the throttle position sensor to disable the egr system, no need to take it off

yella · Aug 13, 2006

if you take it off a blanking plate is available for about 10 quid from ebay

You could always ask Discomania for an opinion - he is the worlds leading expert on EGR, (in his own fornt room anyway)

Or you could leave it alone and let it do its job.

discomania · Aug 13, 2006

Don't take the valve off, simply unbolt the valve, and slip an EGR blanking plate in as yella says form eBay, bolt it back up, and away you go.

As said above, better speed, better MPG.

My front room is rather good actually - nice and cosy,plenty of food,decent booze,good company etc.
Outside is troubled by ****ty politicians who let the oil companies rule the world.Till they wise up and let us have some decent fuel to run our IC engines off,(maybe Canola oil for CI engines and Sugar beet extract for SI engines) I will continue to earn a decent living making LR products run correctly - including EGR systems.I think our kids will look back on us and think how weak we were letting the bastards get away with it for so long.Get rid of fossil fuels and we wouldnt have to worry so much about emissions kit.Read anything about the next generation of small diesels ? Going to be closed loop operation,probably using deflection of the glow plug tips to monitor combustion chamber activity - all with the goal of reducing Nox emissions.Cant see Ebay selling anything to counter that.Like I have said too many times before if the Egr is functioning properly you would be hard pushed to notice any difference.

OK fair enough, you make EGR systems, your hardly going to say what you makes doesn't actully work.

If you would be hard pushed to see an EGR plate making a difference in a working EGR then your systems just damn awful because I have seen it making a huge difference on many LR's right across the board, including several new TD5's...

I think we need to call a truce,you cant even be bothered to read my posts properly - I said I will continue to make a living making LR products work properly - not make /manufacture EGR systems.What do you do on a daily basis ? Where do all these Td5's come from that you liberate all this lost power from ?
Have you spent any time/effort on small CI engine theory/development - do you give a toss that the crap bunch at Whitehall would love to stick £1800,( or whatever they come up with next week)road tax on Land Rovers ?
EGR does not make a noticeable difference to daily driving if it is working properly - if you have a bunch of cars that blocking its function makes such a big difference to then I wish you would point them in my direction - restoring performance and mpg whilst retaining good emissions is a very satisfying task.I cant see why you are so against it.
In ten years time when Mot's are done on automated test lanes with direct connection to the cars EOBD socket you will have no chance of fiddling with things to alter fueling/emissions parameters - could be a good thing if all you are after is maximum performance with no interest in clean air.

Of course I give a toss about that bunch at Whitehall, I think it would be a terrible mistake it would have the ability to destory land rover, not to mention buisness dependent on 4x4's.

Perhaps the EGR system in LR's fails a lot? As in my experience plates have allowed them to get better MPG, and better speed and power.

We will call it a day at that.

One last question; is there any long (or short) term ill effects if using the plate modification?

clutchdust · Aug 15, 2006

no, most rest of world spec vehicles dont have egr

i used to work at a land rover export distributor and all the vehicles that came through our workshop had the plate instaed of egr valve, if the vehicle was going to a country that needed egr for their regs then we retro fitted it

yella · Aug 15, 2006

OK OK OK. THIS THREAD STOPS RIGHT NOW. THIS IS A LANDROVER FORUM NOT A POLITICAL FORUM. PLEASE JUST AGREE TO DIFFER AND SEND EACH OTHER A WINK

eightinavee · Aug 15, 2006

Right oh,

all points made and understood,what can we "discuss" now?
Shame this is on the net - not round a dinner table at 2am after far too much food /booze and the women have tootled of to bed !

discomania · Aug 16, 2006

Lets discuss where we can get far to much food and booze.

discofever · Aug 16, 2006

Come to mine! booze and the wifes a cracking cook....I said cook!!!

OK, now reading more into this - can anyone tell me where the throttle position sensor is? My Haynes manual has a very small diagram that shows me diddly squat, location wise!

discomania · Sep 4, 2006

Its on the injection pump... has 3 pin connector connected to it...

If you look over the engine bay from the right hand side, its on the right hand side of the pump, I guess you could also pull it off at the EGR itself.
