Removing the exhaust gas recirculation valve: is it possible?

Removing the exhaust gas recirculation valve is illegal, except in racing cars. It is really imperative that limit pollution of diesel vehicles... An exhaust gas recirculation valve is also fitted on some petrol models. Removing it may result in a € 7500 fine.

🚗 Removing the exhaust gas recirculation valve: why do it?

La EGR valveThe exhaust gas recirculation system was invented in the 1970s and has been widely adopted since the early 1990s as part of European standards for the abatement of the environment.

Indeed, the role of the EGR valve is to return the exhaust gases to the circuit so that they can undergo a new combustion. This allows reduce nitrogen oxide emissions, or NOx, which are produced by your engine.

Thus, the exhaust gas recirculation valve is a contamination prevention device. She compulsory on vehicles with diesel engine but also equips some gasoline engines.

The problem with the exhaust gas recirculation valve is related to its operation. Forcibly dirty due to calamine... This can block the EGR valve flap and increase the pollution of your vehicle, as well as damage the air intake.

Removing the EGR valve eliminates this problem, but also allows:

• To increase combustion ;
• Improve engine performance ;
• To reduce consumption fuel.

🛑 Can the exhaust gas recirculation valve be removed?

On vehicles with a diesel engine, the exhaust gas recirculation valve is always mandatory... It is also fitted to some direct injection gasoline vehicles to limit pollution.

The exhaust gas recirculation valve is checked during technical control and its malfunction will make you fail. Of course, it's the same with removing it.

But the consequences of removing the exhaust gas recirculation valve can be even greater, since you are breaking the law. You risk getting a fine of up to 7500 €.

Therefore, it is illegal to remove the EGR valve from your vehicle. There is only one exception for which the exhaust gas recirculation valve can be removed: competition.

Indeed, to improve the performance of a race car, its EGR valve can be removed in preparation for a race.

However, this car will not be able to no more road travel after that, otherwise you will be illegal and therefore run the risk of being sanctioned.

👨‍🔧 How to remove the exhaust gas recirculation valve?

Removing the exhaust gas recirculation valve consists of block its valve in the closed position... This is done with an exhaust gas recirculation valve removal kit, which blocks the valve. You can also use barrage plates in the chain.

However, removal of the exhaust gas recirculation valve must also be accompanied by electronic reprogramming motor. Indeed, in order to avoid problems with the engine and the transition of the computer to a mode of reduced performance, it is also necessary to disable the operation of the EGR valve electronically.

Finally, it is also possible, instead of simply removing the exhaust gas recirculation valve, to keep it to a minimum. This will reduce the fouling of the exhaust gas recirculation valve and increase the power of the racing car.

This system consists of placing a performance plate on the system at the level of the duct that connects the inlet and outlet pipes. This allows the passage to be partially blocked so that the gas continues on its way through the exhaust instead of being returned to the intake port by the EGR valve.

Now you know under what conditions you can consider removing the exhaust gas recirculation valve. If you have a problem with your EGR valve, contact our trusted mechanics to have it repaired, serviced or replaced!
