Can the EGR valve of a National IV diesel vehicle be removed?

[DeQuinn]

National IV diesel vehicles cannot operate without the EGR valve, as it affects the vehicle's exhaust emissions. Without it, emissions will not meet the standards, and the vehicle will fail the annual inspection. Here is some additional information: The EGR valve is an electromechanical product installed on gasoline engines to control the amount of exhaust gas recirculated back into the intake system. It is usually located on the right side of the intake manifold, near the throttle body, and is connected to the exhaust manifold via a short metal pipe.
