So you were daft enough to belive a bloke in a shed who tells you that he can improve performance and economy on a car Ford spent millions developing.

Take it to a Ford dealer and get it repaired properly.

So all them thousands of post of people claiming it's better to do it. Guessing they are daft to?

In a word yes. Its also illegal since its a modification to the homogated emmision kit fitted when manufactured. You should also tell your insurers when you modify your car or cover could be refused.

Taking it to a ford dealer I might as well say hey here my wages for the month that should cover it. I've come for advice and all you can do is basically say hey go waste your money.

You have already wasted your money. My suggestion will fix your car.

So, the OP blanks his EGR valve and then complains that his car feels like it's in limp mode. Well guess what? THAT'S EXACTLY WHAT WILL HAPPEN!

When the EGR valve is closed there's only one way for the engine to draw air. Through the air intake via the mass air flow sensor. But when the EGR valve is open there are two ways. This means that the air passing the MAF sensor reduces. The ECM recognises this reduction in air flow and that's how it knows the EGR valve has opened when commanded. If there is no reduction in air flow the ECM will not know if the EGR valve has opened. It will then reduce engine power so that NOx emission levels are maintained.

So the OP should refit his EGR valve and ensure it's clean and working if he wants to restore engine power.

"There me thinking you lot knew EVERYTHING"

The replies have been blunt, but nothing more. The advice is offered as we see it.

And I have to say that there have been countless posters who didn't like the answers when they asked for advice. By all means ignore it and go elsewhere.

I think the problem is not wanting to feel you have made a mistake by blanking off the EGR valve, but that's what it was - a mistake. We all make them.

It's just emissions rubbish and sooner it's gotten rid of the better.

I'm sure people said the same when the Clean Air Act came in to get rid of the city smogs on the 40s and 50s ... Or when we stopped using lead in petrol ...

The EGR valve gets 'gummed up', over enough time, yes. But it's purpose is to re-combust some of the exhaust gasses (which have been through incomplete combustion), and therefore to reduce the amount of pollution pushed out the tailpipe.

This is NOT a mistake, actually it's better for the engine not to be re-breathing all that filthy air. Ever looked in past the EGR valve? invariably it's almost blocked with soot. It's a popular mod on land rover TD5s, doesn't cause any issues. Case in point is that Land Rover didn't fit the EGR to export models! TD5s were produced till 2007.

The mistake here is not the EGR blank, but most likely an ECU issue.

It's just emissions rubbish and sooner it's gotten rid of the better.

My view is simple on this matter.

As well as meeting the vissible smoke requirements if you modify a car and it no longer meets the required emmisions requirements the car should be taken off the road. The owner should get a certain amount of time to get it fixed by an approved garage after which they wopuld forfit the car which would then be crushed or if of suitable market value resold by auction after rectification.

The owner should also get a huge fine for their trouble.

Having seen many modfied diesels locally most of which are drive by young idiots with their caps on back to front displaying "dirty diesel" stickers on the boot belching out huge clouds of black smoke as they boot the throttle there should be one additional penalty. They should be forced to stand behind the car in a sealed workshop while the engine is revved to max for one hour. If they die during the period, tough, if they survive they will surely remember the missery they inflict on others when they are driving irresponsibly.

II'll go against the consensus here and say that blanking the EGR is quite a sensible thing to do in many cases. I did it on my 1.8 tdci Focus and got noticably smoother running and 2-3 extra MPG, a no-brainer for a £2 piece of metal. The only purpose of EGRs is to fudge Euro standards and outside of the lab they make little difference in overall emissions.

The problem that OP has come up against is that it can sometimes confuse ECUs and in worst cases can lead to limp-home mode. Sometimes drilling a small hole in the blank may be enough to keep it happy, at worst a full software delete is called for; many remappers can provide this service.
