Fuel Pump

The Bosch High Pressure Fuel Pump (HPFP) is a critical component for gasoline direct injection (GDI) engines, boosting fuel pressure to over 2,000 psi for precise injection into the combustion chamber. This enhances fuel atomization, improves efficiency, and supports higher power output. Typically driven by the camshaft, the HPFP works with a low-pressure pump to ensure consistent fuel delivery. Failures of this pump can manifest in several ways: issues with the fuel quantity control valve may trigger SAE P0001 fault codes, while internal leaks can allow fuel to contaminate engine oil, leading to negative fuel trim corrections. Symptoms of a failing HPFP include hard starting, hesitation, misfires, loss of power under load, check engine lights, lean/rich codes, or reduced fuel economy. You might also notice ticking or whining sounds from the pump or visible fuel leakage. It meets the stringent standards expected of Genuine BMW parts, often being the original equipment manufacturer (OEM) part found in BMW's own production. This part is compatible with a wide range of BMW vehicles including various models of the 2 Series (230i, 230i xDrive, M240i), 3 Series (330e, 330i, 330i GT xDrive, 330i xDrive, 340i, 340i xDrive), 4 Series (430i, 440i), 5 Series (530i, 540i), 7 Series (740i), and X3, X4 models, spanning various model years from 2014 to 2021. Always verify fitment with your specific vehicle's year, engine, and chassis configuration.
