About this category
This category covers high-pressure pumps for the Renault Scenic 3 1.5 dCi 110, a diesel engine known for its efficiency but sensitive to fuel system failures. These pumps regulate pressure in the common rail, directly impacting engine performance, fuel consumption, and emissions. Whether you are a mechanic sourcing a replacement or an owner diagnosing a fault, understanding the pump’s role is essential to restoring your vehicle’s reliability.
The range is built around exchange-standard units, where remanufactured pumps undergo rigorous testing to meet original equipment standards. As a wholesale supplier, we aggregate these products from trusted manufacturers, ensuring availability for garages and private buyers alike, with no compromise on quality or compatibility.
Professional uses by trade
Different users approach high-pressure pump replacement with distinct priorities: garages need bulk availability and fast turnaround, while private owners prioritize ease of installation and cost efficiency.

How to choose
Selecting the right high-pressure pump involves more than matching the OEM reference; consider the pump’s remanufacturing process, core deposit policies, and supplier reliability to ensure a durable solution.
- Opt for pumps with a documented remanufacturing process, including pressure testing and seal replacement, to deliver consistent performance over time.
- Check the core deposit policy: some suppliers require returning the old pump within a set period to offset the cost of the new unit.
- Prioritize suppliers with a rotating stock of high-pressure pumps to avoid delays, especially for garages handling multiple diesel engine repairs daily.
- Verify the pump’s compatibility with your Scenic 3’s engine code (K9K 836) and model year to prevent fitment issues during installation.
- Choose units with protective packaging to prevent damage during transit, as high-pressure pumps are precision components sensitive to shock.
- Select suppliers offering technical documentation or support to assist with installation, particularly for less experienced mechanics or DIY enthusiasts.
- Ensure the pump’s electrical connector matches your vehicle’s wiring harness to avoid rewiring or adapter complications during the swap.
Storage & logistics
High-pressure pumps must be stored in a climate-controlled environment to prevent corrosion or seal degradation, as moisture and temperature fluctuations can compromise their performance. For wholesale buyers, palletized storage with desiccant packs ensures long-term integrity, while individual units should remain in their original packaging until installation. Avoid stacking pumps directly on top of each other to prevent mechanical stress on the housing or internal components, and always handle them with care to preserve their calibrated state.
Since 2026, we’ve supplied thousands of high-pressure pumps for Renault diesel engines, focusing on remanufactured units that meet OEM tolerances without the premium pricing of new parts.— autoKUR team
