Show original supplier description

The Genuine 13518631642 is a brand-new, OEM high-pressure fuel pump (HPFP) that directly replaces BMW part number 13518631642. This critical component is essential for modern gasoline direct injection (GDI) engines, boosting fuel pressure to high levels (often over 2,000 psi) for direct injection into the combustion chamber, enabling improved fuel atomization, efficiency, and power output. Common failures of this HPFP style include issues with the fuel quantity control valve, leading to pressure faults on the high-pressure side and potentially triggering SAE P0001 fault codes. Internal leaks can also cause fuel to contaminate engine oil, resulting in significant fuel trim corrections. Symptoms of HPFP failure can include engine performance problems like hard starting, hesitation, misfires, or loss of power, as well as check engine lights, lean/rich codes, and reduced fuel economy. Noises such as ticking or whining from the pump, or visible fuel leakage, are also indicators of a failing unit. This Bosch-made HPFP is designed for compatibility with B46D, B58C, B58D, and S58 engines, found in various BMW models and the Toyota Supra. It is specifically noted as being for 2020 and later F48 X1 models with the B46D engine. The pump is an OE-quality part, manufactured in Germany, and meets BMW's standards for fitment, performance, and longevity, often incorporating updates or revisions not found in aftermarket alternatives.
