Discovery 5 L462 EGR Valves
Your Discovery 5's EGR valve recirculates exhaust gases back into the combustion chamber, reducing harmful NOx emissions and meeting strict environmental standards. This critical emissions component operates under extreme conditions, making regular maintenance essential for optimal performance and compliance.
EGR System Operation and Issues
The L462's EGR valve controls exhaust gas flow based on engine load and temperature. Carbon buildup from diesel combustion commonly causes valve sticking, leading to rough idling, reduced power and increased emissions. Our Discovery 5 EGR valve selection includes genuine replacements and quality aftermarket alternatives.
Maintenance and Replacement
Warning signs include engine hesitation, black smoke and illuminated engine management lights. Regular cleaning prevents costly replacements, though severely carbonised valves require replacement. Our technical catalogues provide detailed specifications and fitting procedures.
