The Replacement RM31810002 is a direct-fit aftermarket fuel rail pressure relief valve designed for the Mercedes-Benz E320 CDI equipped with the 3.2L inline 6-cylinder diesel engine. This valve is a critical component of the common rail direct injection (CDI) fuel system, regulating high-pressure fuel within the fuel rail to protect injection system components from over-pressurization.

This part is engineered as an OEM-quality replacement and is a direct substitute for original equipment part numbers 05137291AA and 6480700046 (A6480700046), as well as Bosch reference 0281002682.
