Fuel injector MERCEDES Classe E (W211) 220 CDI 136 hp

The Mercedes-Benz 220 CDI 136 HP diesel engine, found in models from the W203 and W204 generations, relies on a precise fuel injection system to deliver optimal power and efficiency. Over time, injectors wear down, leading to misfires, increased fuel consumption, or even engine damage if left unaddressed. This category provides reconditioned injectors designed specifically for these engines, offering a cost-effective alternative to expensive OEM replacements while maintaining the same level of performance and reliability.

As a specialist in remanufactured automotive components, we source injectors from trusted suppliers and subject them to rigorous testing to ensure they meet the original equipment manufacturer’s specifications. The range is curated to cover all common failure points, including clogged nozzles, worn seals, and degraded electromagnetic coils. By partnering with a wholesale distributor like ours, garages and private owners gain access to a consistent supply of high-quality parts without the delays or premium pricing associated with direct OEM channels.

Range comparison

Below, you will find a selection of reconditioned injectors compatible with the Mercedes 220 CDI 136 HP, covering all common engine codes and model years. Each unit has been tested for spray pattern, electrical resistance, and leak tightness to ensure reliability.

How to choose

Selecting the right injector for your Mercedes 220 CDI 136 HP depends on several factors, including engine code, model year, and intended use. Compatibility is critical to avoid misfires or reduced performance, so always cross-reference the OEM part number with your vehicle’s specifications.

1. Verify the engine code (OM646 or OM651) to ensure the injector matches your vehicle’s fuel system requirements and avoids compatibility issues.
2. Check the model year and generation (W203 or W204) to confirm the injector’s fitment, as slight variations exist between early and late production runs.
3. Assess the injector’s condition by inspecting the nozzle for carbon buildup or corrosion, which can indicate the need for replacement even if the unit is still functional.
4. Consider the injector’s spray pattern and resistance values, as deviations from OEM specifications can lead to poor combustion and increased emissions.
5. Evaluate the injector’s packaging and storage conditions, as improper handling can compromise its performance and longevity before installation.
6. Review the injector’s return policy and core deposit requirements, as some suppliers mandate the return of the old unit to reduce costs and promote recycling.
7. Prioritize injectors from reputable brands like Bosch, as their remanufactured units undergo strict quality control to match original equipment standards.

Storage & logistics

Proper storage of reconditioned injectors is essential to maintain their performance and prevent contamination. Keep units in their original packaging or a sealed, anti-static container to protect against moisture and dust. Store them in a climate-controlled environment, away from direct sunlight and extreme temperatures, which can degrade seals and degrade electromagnetic components. For wholesale buyers, ensure inventory is rotated regularly to prevent shelf life issues, and inspect each batch for signs of corrosion or physical damage before dispatch. Always handle injectors with clean gloves to avoid transferring oils or residues that could affect their operation once installed.
