Fuel injector MERCEDES Sprinter 2 (906) 516 516 CDI 163 hp

This category covers high-pressure injectors for the Mercedes 516 CDI 163 hp engine, a 2.1-liter four-cylinder diesel unit found in models from 2002 to 2009, including the C-Class, E-Class, and Sprinter. These injectors are essential for precise fuel delivery, and their failure often triggers symptoms like misfires, excessive fuel consumption, or a rough idle.

The range is built around OEM-compatible remanufactured injectors, sourced from leading suppliers like Delphi and Bosch, and distributed through a network of automotive wholesalers. Each injector undergoes rigorous testing to restore its original performance, with no deviation from the engine’s design parameters.

Professional uses by trade

Different professionals approach injector replacement with distinct priorities: garages focus on turnaround time and bulk availability, while DIY enthusiasts seek clarity on compatibility and return policies for core deposits.

• Le garagiste independant : Replace worn injectors in batches to minimize vehicle downtime during scheduled maintenance visits.
• L'automobiliste depanne : Order a single injector when a misfire or fuel leak is detected, often after a diagnostic scan reveals the faulty cylinder.
• Le passionne qui fait lui-meme : Verify injector compatibility using the vehicle’s VIN or engine code before purchasing to avoid incorrect fitment.
• Der deutsche Kaeufer (DACH) : Prefer remanufactured injectors with a core deposit system to reduce costs and simplify the return of used parts.
• Le garagiste independant : Stock injectors for multiple Mercedes models to handle emergency repairs without waiting for supplier lead times.
• L'automobiliste depanne : Check for visible signs of injector failure, such as fuel leakage or carbon buildup on the nozzle, before ordering a replacement.
• Der deutsche Kaeufer (DACH) : Request injectors with a documented remanufacturing process to ensure consistent performance over time.

Below are the remanufactured injectors available for the Mercedes 516 CDI 163 hp, each tested for flow rate, spray pattern, and electrical integrity before packaging.

How to choose

Selecting the right injector involves balancing cost, availability, and the specific needs of the repair scenario, whether it’s a routine service or an emergency replacement.

1. Prioritize injectors with a documented remanufacturing date to ensure they meet current performance standards for the OM646 engine.
2. Choose bulk packaging for workshops to reduce handling time and streamline inventory management during high-volume repairs.
3. Opt for injectors with a core deposit system to lower upfront costs and simplify the return of used parts to the supplier.
4. Verify the injector’s spray pattern and opening pressure using a flow bench before installation to confirm compatibility with the engine’s fuel system.
5. Select injectors from suppliers with a track record of consistency, as variations in calibration can lead to uneven engine performance.
6. For performance-tuned engines, consider high-flow injectors that maintain accuracy at elevated rail pressures.
7. Ensure the injector’s electrical connector matches the vehicle’s wiring harness to avoid fitment issues during installation.

Storage & logistics

Bulk-packaged injectors should be stored in a climate-controlled environment, away from direct sunlight and moisture, to prevent corrosion or damage to the electrical components. For workshops, organizing injectors by engine code and model year in labeled bins improves retrieval speed during repairs. Always handle injectors with care, avoiding contact with the nozzle or electrical terminals to maintain their precision calibration. Regularly inspect stored injectors for signs of degradation, such as cracked seals or corroded connectors, and rotate stock to ensure the oldest units are used first.
