About this category
The 2.0 HDi 136 hp engine, widely used in Citroën models from the mid-2000s onward, is known for its direct-injection diesel technology that delivers both power and efficiency. When injectors fail—often signaled by rough idling, misfires, or excessive smoke—replacement becomes urgent. This category offers exchange-standard injectors designed to restore factory-level performance without the premium of new OEM parts, making them ideal for independent garages, DIY enthusiasts, and fleet managers seeking cost-effective solutions.
Each injector in this range is sourced from reputable remanufacturers who rebuild components to original specifications, ensuring durability and compatibility.

How to choose
Selecting the right injector depends on factors like engine code, model year, and expected usage—whether for a daily driver or a performance-tuned vehicle.
- Verify the engine code stamped on your cylinder head to match the injector reference precisely and avoid compatibility errors.
- Choose bulk-packaged injectors for workshops to reduce per-unit costs and streamline inventory management during high-demand periods.
- Opt for single-unit purchases if you’re a DIY mechanic or owner replacing just one faulty injector to minimize upfront investment.
- Prioritize injectors labeled for your specific model year to ensure optimal fit and performance in your Citroën’s fuel system.
- Check for remanufactured injectors with a documented core deposit system to simplify returns of your old part and reduce hassle.
- Select injectors from brands with a reputation for consistent quality to ensure long-term reliability and minimal risk of repeat failures.
- For turbocharged variants, choose injectors designed for higher flow rates to maintain power output and prevent premature wear.
Storage & logistics
Bulk-packaged injectors should be stored in a dry, temperature-controlled environment away from direct sunlight to preserve their seals and internal components. For garages, organizing injectors by vehicle model and engine code in labeled bins streamlines retrieval and reduces the risk of misplacement. Always handle injectors with care, avoiding drops or impacts that could damage the delicate internal mechanisms, and ensure packaging remains intact until installation to prevent contamination.
