EGR delete without a remap of the ECU will give no performance benefit but will increase emissions. But it does simplify things greatly. A remap is unlikely to give collossal gains in power, but there will be some.
Subsequently, What is the purpose of EGR in diesel engine?
Abstract: Exhaust gas recirculation (EGR) is an effective strategy to control NOx emissions from diesel engines. The EGR reduces NOx through lowering the oxygen concentration in the combustion chamber, as well as through heat absorption.
then, Is removing EGR valve illegal?
Although it is not illegal to remove the EGR from your vehicle, it is an offence under the Road vehicles (Construction and Use) Regulations (Regulation 61a(3))1 to use a vehicle which has been modified in such a way that it no longer complies with the air pollutant emissions standards it was designed to meet.
Thereof Is it OK to block off EGR valve? If the EGR valve is clogged or completely blocked off it can longer re-burn harmful emissions in the combustion chamber. The NOx emissions will flow unregulated through the combustion chamber and out of the exhaust pipe. The excessive NOx emissions will show up during a smog test and cause a failure.

What causes EGR to fail?
The failure of the EGR valve on the vehicle is not out of the ordinary, as this issue can arise on most modern diesel engines. The failures are usually caused by a build-up of deposits in the EGR valve over a period of time that causes them to stick.
Will removing EGR valve fail MOT?
Why EGR valve removal is worth it
A clogged EGR valve will become stuck in an open or closed position and this can lead to irreversible turbo and engine damage. Due to this, many motorists choose to have EGR valve removal. This is perfectly legal. A car will not fail its MOT because it has had an EGR valve removal.
Can I disconnect my EGR valve?
If you unplug it, while the truck is off, then the EGR will stay closed. If the EGR valve is clogged or completely blocked off it can longer re-burn harmful emissions in the combustion chamber. You’re now sending the exhaust gas away from the engine when using an EGR delete kit, which means it begins to run cleaner.
Can I replace my EGR valve myself?
