Removing EGR valve is something iv been planning to do for a while but how can I stop the ecu throwing a fault code if I remove it?
Thanks in advance

Could you be any more vague on what engine, car or even fuel system?

I doubt it.

Duct tape over the bulb is all i could suggest from your detailed and comprehensive question.
On an unrelated note i'm going to prepare some food, how long should i cook it for?

Apologies for the lack of detail, the engine is the M15a from the Suzuki Ignis Sport, petrol.
The EGR its self is a stepper motor which is bolted to the cylinder head with a pipe into the intake manifold.

I know that disconnecting the cable will result in a engine light, so I want a more permanent fix but the only one I can come up with is removing the pipe to the intake so it vents into the engine bay but not sure that is a good idea for hot exhaust gas.

Slipping a blanking plate in between two halves of a joint is normal practice.

If they don't make a blanking plate for your car you can take a coke can, unravel it, draw the outline of the gasket on it and cut it out carefully. The light may still come on as a lot of cars look for a drop in the output from the air flow meter corresponding to the amount of egr requested. If this happens you need to get a remap to solve that.

You re-program the ecu so the fault light no longer comes on.

Why do you want to do this anyhow?

That's very helpful thanks, reason for removal is like most people, I don't want exhaust gases in the intake, it's only befit is to reduce NOx gases and it only works when the engine is at operational temp, and when the throttle position is within a certain range.

So you think polluting the atmosphere is a good thing? scratchchin

I don't think you've really thought this one through.

And why do you think EGR is costing you power, given at higher loads it does nothing to inhibit power ?

I will admit that morally I'm not sure I should when I use it as a Road car, however if in the near future I use it for competition use then I would like to remove the EGR completely

So you are saying that at lower loads it does?

At lower loads your right foot will be reducing power more than the EGR system ever will. Hence the term "lower loads"......

So the EGR is sapping some of the engine's power then?

Yes, and reducing mpg, increasing particulate and co2 emissions and clogging up the intake

Well, from August this year, the DVSA will be conducting roadside checks on commercial vehicles for 'emission cheat devices' including the removal of EGR valves. How long before they start checking cars?

They already do, and have done in one way, shape or form for years.

I was pulled over for a "spot check" at a layby just south of Horncastle around 8 years ago now, traffic gadgie looked underneath for a cat & did a roadside emissions check.

It is exceedingly rare, but I have seen similar goings-on in laybys since a few times, they randomly pull over a car every few mins to check.
