About this category
The 1.5 dCi 110 engine, found in Renault Scenic 3 models from 2009 to 2014, is known for its durability but sensitive fuel injection components. This category covers Bosch injectors designed for direct replacement, addressing issues like misfires, excessive fuel consumption, or hard starts. Whether you’re a professional mechanic or a DIY enthusiast, finding the right injector means matching the engine’s power output and emission standards without compromising reliability.
This range is built around Bosch’s remanufactured injectors, which undergo rigorous testing to restore factory specifications. As a wholesale supplier, we aggregate these parts from certified remanufacturers, ensuring consistent availability and competitive pricing for garages and parts distributors across Europe. The focus remains on exchange-standard units, where the core deposit system allows for cost-effective returns of used injectors.
Professional uses by trade
Different users approach injector replacement with distinct priorities: garages prioritize bulk availability and traceability, while DIY owners seek clarity on compatibility and installation ease. Professionals and enthusiasts alike benefit from understanding the injector’s role in the engine’s combustion cycle.
- Le garagiste independant : Replaces faulty injectors in batches to minimize vehicle downtime during scheduled maintenance or diagnostic repairs.
- L'automobiliste depanne : Orders a single injector when a misfire or fuel leak is detected, often after a diagnostic trouble code points to cylinder imbalance.
- Le passionne qui fait lui-meme : Researches injector compatibility for a 2012 Scenic 3 1.5 dCi 110 before purchasing, ensuring the replacement matches the engine’s power output and emission standards.
- Der deutsche Kaeufer (DACH) : Seeks remanufactured Bosch injectors with core deposit options, aligning with local environmental regulations and cost-saving practices.
- Le garagiste independant : Uses injector sets for engine tuning or performance upgrades, where precise fuel delivery is critical for power gains without compromising longevity.
- L'automobiliste depanne : Verifies injector part numbers against the vehicle’s VIN or engine code to avoid mismatched replacements that could trigger check engine lights.
- Der deutsche Kaeufer (DACH) : Prefers injectors with documented remanufacturing processes, ensuring compliance with EU emissions standards and extended warranty terms.

How to choose
Selecting the right injector involves more than matching part numbers—it requires understanding the engine’s operating conditions and the injector’s role in fuel delivery. Professionals should prioritize units with verified spray patterns and electrical resistance within OEM tolerances.
- Conditioning: Opt for injectors with documented remanufacturing processes, including ultrasonic cleaning and nozzle testing to restore factory precision.
- Conservation: Store injectors in sealed, anti-static packaging to prevent contamination before installation, especially in humid or dusty workshop environments.
- Regularity: Choose injectors from batches with consistent flow rate measurements, ensuring balanced fuel delivery across all cylinders for optimal engine performance.
- Rotation: For fleets or high-volume garages, select injectors with long shelf lives and minimal degradation over time, reducing the need for frequent replacements.
- Compatibility: Verify the injector’s OEM reference against the vehicle’s engine code (K9K 836 or similar) to avoid mismatches that could trigger fault codes or reduce efficiency.
- Core deposit: Prioritize suppliers offering core deposit programs, where returning the old injector reduces the net cost of the replacement part.
- Traceability: Request documentation proving the injector’s remanufacturing origin and testing standards, providing confidence in its long-term reliability.
Storage & logistics
For wholesale buyers, proper storage of injectors is critical to maintaining their performance. Keep units in climate-controlled environments, away from direct sunlight and temperature fluctuations, which can degrade seals and affect spray patterns. Use original packaging or anti-static containers to prevent electrostatic discharge, a common cause of injector failure. Rotate stock regularly to ensure older units are used first, and inspect packaging for damage before accepting deliveries. For garages, storing injectors in sealed bags with desiccant packets helps prevent moisture buildup, which can corrode internal components over time.
