The function of the EGR valve is to reintroduce a percentage of exhaust gases into the intake to lower their temperature and reduce NOx emissions. The constant contact with exhaust gases, often contaminated with oil vapours and unburned diesel, tends to dirty the valve, potentially causing it to stick, often in the open position, allowing exhaust gases to continuously leak into the intake, adversely affecting engine performance.

It is advisable to frequently clean this valve as well as the intake manifold. Open the front bonnet, remove the plastic cover above the engine, and disassemble the air filter box to access the EGR valve located centrally, just behind the engine.

Disconnect the connector from the actuator and unscrew the fastening pins of the valve to extract it from its housing. Then, remove the metal gasket and disassemble the pipe connecting the exhaust manifold to the intake manifold.

Clean the valve and pipe with appropriate cleaner, ensuring no dirt enters the intake manifold, and proceed in reverse for reassembly.
