Bosch 0 445 010 757 High-Pressure Pump, CR System – CP4HS1/L50/10 (Mercedes-Benz OM654)
The Bosch 0 445 010 757 is a common-rail high-pressure fuel pump built to type formula CR/CP4HS1/L50/10, supplied as original equipment on Mercedes-Benz’s OM654 generation 2.0-litre four-cylinder diesel engine. Fitted across the OM654 platform from 2016 onward in models including the C-Class, E-Class, CLS, and GLC, this CP4-series pump is a common failure point on high-mileage OM654 engines and a frequent search for diesel workshops sourcing a genuine or remanufactured replacement. The reference data below covers Bosch and Mercedes-Benz OEM part numbers, engine and vehicle applications, and technical specifications for 0 445 010 757.

Fuel Injection System Type
The 0 445 010 757 is a Bosch CP4-series high-pressure pump for common-rail (CR) fuel injection. Unlike the mechanical VE and PE distributor and in-line pumps used on earlier diesel engines, the CP4 is camshaft-driven and pressurises fuel via radial pumping elements, feeding a shared high-pressure rail that supplies all injectors independently of injection timing at the pump itself. Fuel pressure and delivery quantity are controlled electronically through the engine ECU via a pressure control valve and metering unit, allowing rail pressures far higher than mechanical distributor pumps can achieve and enabling the multiple injection events per cycle required for modern emissions compliance. On the OM654 platform this pump is driven directly off the engine’s intake camshaft.
Engine Application
| Engine Code | Type | Displacement | Power Output | Rated Speed |
|---|---|---|---|---|
| OM654.920 | Mercedes-Benz OM654, turbocharged common-rail diesel, inline 4-cylinder | 2.0 L (1,950 cc) | 143 kW (194 PS) | 3,800 rpm (rated power); peak torque 400 Nm at 1,600–2,400 rpm |
The wider OM654 engine family covers multiple power derivatives sharing the same 2.0 L (1,950 cc) block, ranging from approximately 110 kW (150 PS) to 143 kW (194 PS) in the standard “200/220d” tunes fitted from 2016 onward, with later high-output “OM654 M” variants reaching up to 195 kW (265 PS). The exact power derivative and OE pump number fitted depend on model year and market – confirm the specific OM654 sub-variant against the vehicle’s engine code plate or VIN before ordering.
Vehicle Application
| Model | Chassis Code | Years of Manufacture |
|---|---|---|
| C 220 d | W205 / S205 | 2018–2021 |
| E 220 d | W213 / S213 | 2016–2023 |
| CLS 220 d | C257 | 2018–2023 |
| GLC 220 d | X253 | 2019–2022 |
| B 220 d Sports Tourer | W247 | 2018–ongoing (compatible part 0 445 010 758) |
This model list reflects the OM654.920 fitment pattern confirmed against parts catalogue data and is representative rather than exhaustive – the OM654 was also fitted to the A-Class, B-Class, CLA, GLA, and GLB across the same period at varying power outputs. Cross-check the exact chassis, model year, and OE pump suffix against the vehicle’s VIN before ordering.
