This high-pressure common-rail diesel fuel pump assembly (Part No.: 0445010654 / 0 445 010 654; common cross-references and OE interchange codes include 9802540180, 9802540180-00, 0445010655, 0445010656, 0445010825, 0986437435, etc.) is precision-engineered. Designed for 1.5L and 1.6L inline-four diesel engines (including the 1.5 HDi/BlueHDi and 1.6 HDi series)—commonly found in compact passenger cars, urban crossovers, business MPVs, and light commercial vans—it serves as the core power source for the electronically controlled common-rail system. It is responsible for rapidly pressurizing low-pressure diesel and delivering it stably to the high-pressure rail, ensuring a consistent and ample fuel supply across various engine speeds.
The component is designed to meet standards of "precision fit and stable high-pressure output." The pump body is constructed from high-strength forged alloy steel, while internal plunger assemblies and control valve spools utilize specially selected, hardened bearing steel. These parts feature a high-density, ultra-wear-resistant hardened coating that effectively prevents scratches and pressure loss caused by fuel impurities. Upon installation, drivers and technicians will notice significant improvements: crisp cold starts, reduced pump noise during low-speed idling, and smoother engine operation. During rapid acceleration, overtaking, steep hill climbs, or long-distance highway cruising, the throttle response is sharp and robust, delivering linear power without lag, resulting in excellent fuel efficiency and a smooth driving experience.
Problem Solved: Addresses issues such as excessive markups by intermediaries and manufacturing inconsistencies—specifically loose assembly tolerances, uneven fuel delivery pressure across cylinders, and risks of high-pressure leaks.
Value Delivered: Leverages standardized production bases for end-to-end quality control and eliminates unnecessary markups. Ensures highly consistent fuel delivery pressure and flow rates across all cylinders, providing reliable power for vehicle operation while reducing maintenance budgets.
Problem Solved: Addresses common issues with low-quality replacements, such as significant pressure fluctuations, pressure-release valve sticking (causing engine misfires and vibration), and the wasted time and expense of repeated disassembly and adjustment.
Value Delivered: Every high-pressure pump undergoes dynamic simulation on automated test benches before leaving the factory. Distribution pressure and sealing performance are precisely calibrated across various speeds and loads, ensuring "ready-to-install" convenience and significantly saving time and costs associated with installation and tuning.
Problem Solved: Addresses the high operational demands of commercial and daily-use vehicles, where fuel system failures can lead to costly downtime and delays.
Value Delivered: Warehousing centers maintain ample stock of popular models year-round. Orders are processed quickly and shipped within 24–48 hours, drastically reducing logistics wait times and helping owners get vehicles back on the road faster to avoid losses from downtime.
Problem Solved: Addresses premature wear and seizing of plunger assemblies caused by poor diesel lubricity or sulfur impurities in certain regions.
Value Delivered: Core components utilize high-hardness special alloys and corrosion-resistant surface treatments, significantly enhancing fatigue and wear resistance. Stable pressure output is maintained even under harsh environments and prolonged high-load operation, preventing the extra costs associated with frequent repairs.

Daily urban commuting and diesel passenger vehicle usage: Diesel passenger cars and SUVs frequently encounter stop-and-go traffic and repeated starts, placing high demands on the high-pressure pump regarding pressure build-up speed and idle stability. Mechanics should replace the unit with this high-pressure fuel pump when drivers notice sluggish acceleration, insufficient power when climbing hills in high gears, or slow fuel pressure build-up at idle. After installation, oil pressure builds up smoothly and rapidly, and throttle response becomes crisp and agile, effectively enhancing ride quality and fuel efficiency.
Intercity delivery and commercial MPV operations: Commercial passenger vehicles and small logistics vans frequently operate on intercity routes, often cruising at full load for extended periods. When vehicles experience sluggishness on steep inclines under heavy loads, abnormal fuel consumption, or engine misfires, maintenance teams install this high-spec high-pressure fuel pump assembly. Precise flow and pressure control restore the engine's robust power output, improve fuel efficiency, and ensure timely delivery.
Q: Can the product be installed immediately upon receipt? Is additional calibration required?
A: Each high-pressure fuel pump undergoes full-range pressure and flow calibration before leaving the factory. Provided the fuel lines are clean, professional technicians can install the unit—adhering to standard torque specifications for connections and bleeding air from the fuel system—and put it directly into service.
Q: What are the lead times and stock availability for bulk orders?
A: We operate our own manufacturing facilities and large-scale warehouses, maintaining substantial stock of this model. Standard orders can be shipped within 24–48 hours, and we can arrange rapid production scheduling for large-volume orders.
Q: What quality inspections does the product undergo before leaving the factory?
A: All fuel pumps are assembled in Class 100 cleanrooms and undergo 100% dynamic bench testing at high temperatures and ultra-high pressures. We strictly monitor pressure buildup, fuel return volume, and sealing performance to ensure stable on-vehicle operation.
Q: What is the warranty period, and how are quality issues handled?
A: We offer a 12-month warranty on this product. Should any performance failure occur due to non-human factors during the warranty period, we provide rapid replacement or technical support to safeguard your interests.
