Yes a car can run without an EGR valve

Exhaust gas recirculation

In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in petrol/gasoline and diesel engines. EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders.

but it will not run as efficiently and may produce more emissions. What are the consequences of removing the EGR valve? The main consequence of removing the EGR valve is an increase in emissions. Can I drive with a bad EGR valve?

Technically you can drive without a working EGR valve.
It won't affect the health of your engine, but it will hurt the environment. The role of your EGR valve is to reduce the number of toxic NOx gases in the air, so if it isn't working quite right, more toxic gases will be released into the air.

Can I just remove the EGR valve?

It is 100% legal to remove the EGR system from your vehicle and the EGR system is not a part of the MOT test. This may be tightened up in the future but for now EGR removal is safe and legal.

Will an engine run without an EGR valve?

Reduces compression temperature in cylinder. So without EGR the Engine will run Hotter. There is an increased stress and pressure on the cooling system. which when fails can destroy an engine within minutes.

What happens if I delete my EGR valve?

Your engine now has to work less hard to deliver the same amount of power, burning less fuel in the process. Finally, your engine is going to have a longer lifespan. Soot deposited within the engine stresses the system and causes parts to wear down faster.

What happens when you block off the EGR valve?

Blocking off the egr may help stop build up in the inlet manifold, but the egr pipe will soon build up heavily right back into exhaust manifold and turbo.

What damage can a faulty EGR valve cause?

A faulty EGR valve can cause problems with the flow and operation of the EGR system leading to performance issues including a reduction in power, reduced acceleration and decreased fuel efficiency. It can also cause vehicle emissions to increase.

What are the benefits of EGR delete?

An EGR delete consists of using a delete kit to remove the system. The benefits include an improvement in engine performance, fuel economy and not having to worry about emergency maintenance on the EGR (or even the engine itself).

Does blanking EGR improve performance?

AlliSport have developed a range of EGR (Exhaust Gas Re-circulation) Valve replacement and removal kits fit a wide range of on and off road vehicles, which not only improve performance but enhance fuel economy and efficiency.

Is the EGR valve important?

According to Delphi Technologies, an auto parts and technology company, the valve is important because it regulates the flow of exhaust gases to the engine intake system, resulting in increased engine efficiency, reduced fuel consumption and lower nitrogen oxide pollutant emissions.
