Fuel Metering Valve F00N210381 = F00N210223 For Bosch CP1 CP3 Diesel Pump

The Bosch F00N210381 (equivalent to F00N210223) is a genuine fuel quantity control valve, designed for precise regulation of diesel flow into the high-pressure pump. Installed on Bosch CP1 and CP3 series common rail pumps, this metering unit plays a crucial role in maintaining optimal rail pressure under all engine load conditions.

As an essential component in Bosch's electronic diesel control (EDC) system, this valve is trusted by OEMs and technicians alike for consistent performance, durability, and seamless integration.

• Real-Time Pressure Regulation: Adjusts fuel flow dynamically based on ECU signals to maintain rail pressure between ~250–1600 bar.
• Electronically Actuated: High-speed solenoid enables rapid and accurate opening of the control orifice.
• Stable Idle & Efficient Combustion: Prevents pressure fluctuation at idle and improves fuel economy under acceleration.
• Low Emissions Support: Ensures consistent atomization and combustion, helping engines meet Euro 5/6 standards.

A fleet maintenance manager for diesel Mercedes Sprinters noticed multiple vans showing slow acceleration and fuel consumption increases. Diagnostics revealed unstable rail pressure. Replacing the F00N210381 valves restored performance, stabilized fuel pressure, and improved fuel economy across the fleet-saving thousands in fuel and downtime.

• Hard starting or no-start conditions
• Unstable idle or engine stalling
• Delayed throttle response
• Excessive smoke or poor fuel economy
• DTC codes related to rail pressure sensors (e.g., P0087, P0089)

Note: These symptoms often mimic faulty high-pressure pumps or injectors, but replacing the metering valve often solves the issue at a much lower cost.
