The Mercedes-Benz OM642 is a 3.0L V6 CDI (common rail diesel) engine — one of Mercedes-Benz's most widely deployed diesel powerplants, fitted across the CLK, ML, GL, R, and G-Class model ranges. The Bosch CP3 high-pressure fuel pump pressurizes fuel to the common rail system, supplying all six injectors with precisely metered high-pressure fuel for clean combustion and smooth power delivery. When the high-pressure pump fails, fuel rail pressure drops — causing hard starts, rough running, power loss, excessive black smoke, or a complete no-start condition. This remanufactured Bosch CP3 high-pressure fuel pump is a direct replacement covering six cross-reference formats across Bosch and Mercedes-Benz OEM part numbers.
