Range comparison

Below, you’ll find the exchange standard injectors available for the Mercedes-Benz 414 CDI 143 hp, listed with their exact reference numbers and core return policies to simplify your selection.

How to choose

Selecting the right injector involves more than matching the reference number—consider the injector’s condition, packaging, and compatibility with your repair workflow to avoid delays or mismatches.

1. Condition: Choose between general-overhauled or factory-remanufactured units to balance cost and longevity for your specific repair scenario.
2. Packaging: Bulk orders should arrive in protective trays to prevent damage during transit, while single units need individual sealing to maintain cleanliness.
3. Brand consistency: Stick to Delphi or Bosch for known compatibility with the OM646 engine’s high-pressure common rail system.
4. Core return: Always check the core deposit policy to ensure a smooth exchange process when returning the faulty injector.
5. Rotation: Verify the injector’s production date to avoid parts that have been in storage for extended periods, which may affect performance.
6. Compatibility cross-check: Confirm the injector’s fitment with your vehicle’s exact motorization code and production year before ordering.
7. Wholesale pricing: Compare bulk rates across suppliers to secure the best value without compromising on part quality.

Storage & logistics

For garages and bulk buyers, storing exchange injectors requires a climate-controlled environment to prevent seal degradation or corrosion. Units should be kept in their original packaging until use, with desiccant packs added if stored for more than three months. Always handle injectors by the body to avoid damaging the delicate nozzle or electrical connections, and rotate stock to ensure the oldest units are used first. Returned cores should be cleaned of fuel residue and stored separately to avoid contamination of new inventory.
