coppied from nathan in another thread.

The EGR valve allows an amount of exhaust gases back through to the inlet runners to basically be reburnt. This helps lower emissions, as there will be a small amount of unburnt fuel in the gases still.

So the pros of removing EGR is all the air/fuel mix that makes its way into the cylinders will be fresh and also at a lower temperature (Obviously the recycled gases will be hot already and therefore raise the temperature of the air/fuel mix, which we all know loses a few BHPs for every degree).

The cons of removing it are higher emissions and possibly lower MPGs. Also if you remove the EGR you need to ground the connection else it will throw a cel.

just had a read up on the how to section about this . I originally removed my egr valve as the light use to come on but it wouldn't come on straight away .its the same without it plugged in as well. if you thrash the car the light doesn't come on but as soon as you drive normally it comes on. could there be a fault with the wiring somewhere. cheers Jon
