Bosch 0 281 002 738 Common Rail Pressure Control Valve

The Bosch 0 281 002 738 is a common rail pressure control valve (PCV) designed for diesel fuel injection systems. This precision-engineered component regulates fuel rail pressure in high-pressure common rail systems, ensuring optimal fuel delivery to the injectors.

Function and Purpose:

This pressure control valve is mounted directly on the fuel rail and regulates system pressure by controlling excess fuel return to the tank. It acts as a critical component in maintaining precise fuel pressure levels required for efficient diesel combustion, helping to reduce emissions and fuel consumption while ensuring reliable engine performance.

Key Features:

• Genuine Bosch OEM quality component
• Precision pressure regulation for common rail diesel systems
• Direct replacement for worn or failed pressure control valves
• Designed for high-pressure diesel fuel applications
• Prevents hard starting and pressure-related performance issues

OEM Cross-References:

This valve is also known by BMW part numbers 13537795862, 13537805734, 7795855, and 7805734. Bosch alternative designation: CR/DRV-US AK/20S.

Failed pressure control valves are a common cause of hard starting, rough idle, and loss of power in diesel vehicles. Replacing a faulty PCV restores proper fuel system operation and eliminates fuel pressure-related diagnostic trouble codes.
