This electronically controlled high-pressure common-rail diesel fuel injector assembly (Part ID: 0445110103 / 0 445 110 103; common OE cross-references include 0445110102, 0986435058, 6110701487, A6110701487, etc.) is precision-engineered. Designed for the OM611/OM612 series (2.1 CDI/2.7 CDI) diesel engine platforms, it is widely used in models such as the Sprinter (208/308/311/313/411/413 CDI) commercial vans, as well as the E-Class (220 CDI) and C-Class (200/220 CDI) passenger and light commercial vehicles. As a core actuator within the fuel supply system responsible for controlling diesel atomization quality and pulse injection timing, it precisely meters high-pressure diesel and rapidly disperses it into ultra-fine particles in response to millisecond-level electrical signals, thereby facilitating thorough mixing and combustion with the intake air.
The component is manufactured to standards emphasizing "micro-level precision fit" and "millisecond-level rapid response." The core control valve spool and nozzle needle assembly are crafted from aerospace-grade, hardened special alloy steel, featuring ultra-high-precision geometric grinding and low-friction polishing. The surfaces are finished with a dense, ultra-hard coating that effectively prevents internal scratching and pressure loss caused by impurities in the diesel fuel. After installation, drivers and mechanics will notice immediate improvements: crisp, clean cold starts and whisper-quiet, vibration-free idling. Whether climbing steep hills, stop-and-go driving, or cruising long distances, the throttle response is sharp and precise, delivering smooth, robust acceleration. Additionally, it reduces black smoke emissions, ensuring excellent fuel efficiency and a stable, comfortable driving experience.
Standardized smart manufacturing and quality control from the source factory.
We eliminate issues common with intermediary distribution—such as excessive assembly tolerances, uneven cylinder fuel delivery, and high-pressure leakage risks—while effectively lowering procurement costs. By utilizing a standardized production base with end-to-end quality control and removing unnecessary markups, we ensure consistent fuel injection pressure and flow across all cylinders. This reduces maintenance budgets while providing reliable, robust power for vehicle and equipment operations.
Rigorous testing on ultra-high-pressure digital dynamic test benches.
We address common problems found in low-quality replacements—such as response lag, pressure-loss-induced sticking (causing engine misfires and vibration), and the wasted time and money associated with repeated installation and tuning. Every injection component undergoes automated testing before leaving the factory. Flow rates and sealing integrity are precisely calibrated across various pressure ranges in environments simulating real-world high-temperature, ultra-high-pressure conditions. This ensures "ready-to-install" performance, drastically saving time and costs on installation and adjustment.
Large-scale warehousing and rapid shipping response.
Recognizing that daily commuter and commercial transport vehicles are high-utilization assets, we aim to prevent the costly downtime and revenue loss caused by fuel system failures. Our warehouse maintains ample stock year-round; orders are packed and shipped within 24–48 hours of confirmation. This significantly shortens logistics wait times, helping fleets and owners get back on the road quickly and avoid losses due to vehicle downtime.
Specialized quenched alloy needle valves and wear-resistant hardened coatings.
Designed to combat issues where poor diesel lubricity or high sulfur content leads to premature component wear and valve core sticking. Key components utilize high-hardness specialty bearing steel and undergo surface anti-corrosion treatment, significantly enhancing fatigue and wear resistance; they maintain stable performance even under harsh conditions and prolonged high-load operation, thereby reducing additional costs associated with frequent disassembly and repair.

High-frequency long-haul transport for commercial vans and logistics vehicles:
Light commercial vans frequently operate in intercity logistics and business delivery roles, often running at full load and cruising over long distances. Mechanics should replace the complete set of injectors if symptoms such as sluggish starting, severe idling vibration, or stalling under high load occur. After replacement, the engine returns to quiet, smooth operation with responsive, robust throttle delivery, effectively ensuring timely intercity transport.
Diesel Passenger Car Scenarios (Daily City Commuting & Highway Cruising):
Diesel sedans frequently stop and start in urban traffic, placing high demands on fuel delivery response and idle stability. When owners notice significant idle vibration, sluggish acceleration during overtaking, or excessive exhaust smoke, maintenance technicians can promptly install this high-precision common-rail fuel injector. Post-installation, fuel injection response is swift and precise, engine idling becomes quiet and smooth, and power is delivered steadily the moment the throttle is lightly pressed.
Q: Can the product be used immediately after installation, or is a correction code required?
A: Each injector is assigned a unique flow correction code (IMA/QR code) during factory testing. We recommend using a diagnostic tool to program this code into the engine control unit (ECU) after installation to ensure optimal fuel efficiency and smooth operation.
Q: What are the stock levels and lead times for bulk orders?
A: We operate our own factory and large-scale warehouses, maintaining substantial stock of this model year-round. Standard orders are packed and shipped within 24–48 hours, while bulk orders can be quickly scheduled for production.
Q: How are product quality and performance ensured before shipment?
A: All injectors undergo assembly in a Class 100 cleanroom and 100% bench testing across all operating conditions. Tests cover critical metrics such as sealing integrity, pilot injection volume, full-load injection volume, and fuel return volume; our rigorous standards ensure that every unit shipped is a high-quality product.
Q: What is the warranty period, and how is after-sales support handled?
A: We offer a 12-month warranty. Should a performance failure occur due to non-human factors within the warranty period, we provide rapid replacement or technical support to ensure a worry-free experience.
