About this category
The 1.6 D Multijet 1.05 hp diesel engine family, widely used in compact and mid-size vehicles across Europe, demands precise fuel delivery to maintain efficiency and emissions compliance. This category covers high-pressure pumps designed for these engines, offering a critical component in the common rail system that ensures consistent pressure and timing. Whether you are a professional mechanic, a DIY enthusiast, or a vehicle owner facing performance issues, finding the right pump is essential to restoring your engine’s responsiveness and reducing harmful emissions. autoKUR provides these pumps in exchange standard, meaning you receive a remanufactured unit that meets the original performance standards without the premium price of a new OEM part.
This range is built around the core function of the high-pressure pump: delivering diesel fuel at pressures up to 2,000 bar to the injectors, ensuring optimal combustion. The pumps listed here are sourced from reputable suppliers who specialize in remanufacturing, where worn components are replaced, pressure sensors recalibrated, and seals renewed to restore factory-level performance. The role of the wholesaler in this process is to aggregate these remanufactured units, verify their compatibility with specific engine codes, and ensure they are ready for immediate installation. This approach bridges the gap between the high cost of new OEM parts and the reliability required for professional repairs, making it a practical solution for both garages and private owners.

How to choose
Selecting the right high-pressure pump involves more than matching the OEM reference; it requires understanding the pump’s condition, compatibility, and the vehicle’s specific needs. Professionals and DIYers alike should consider factors such as pressure consistency, seal integrity, and the pump’s history to ensure a long-lasting repair.
- Conditioning: opt for pumps that have been remanufactured with new seals and calibrated pressure sensors to ensure consistent performance over time.
- Compatibility: verify the pump’s fitment with your vehicle’s engine code and model year to avoid installation issues or performance mismatches.
- Conservation: choose pumps stored in controlled environments to prevent moisture damage or seal degradation before installation.
- Rotation: select pumps from suppliers with a fast turnover to ensure you receive a unit that has not been sitting in storage for extended periods.
- Pressure curve: ensure the pump’s pressure delivery matches the engine’s requirements to maintain optimal combustion and emissions compliance.
- Core deposit: consider pumps available with a core deposit system, allowing you to return the old pump for a refund, reducing waste and costs.
- Supplier reputation: prioritize pumps from suppliers known for rigorous testing and remanufacturing standards to deliver reliability.
Storage & logistics
For garages and wholesalers, proper storage of high-pressure pumps is critical to maintaining their performance and longevity. These pumps should be kept in a dry, temperature-controlled environment to prevent seal degradation or corrosion, which can compromise their function. Avoid storing them near chemicals, fuels, or other contaminants that could affect the seals or internal components. Regularly inspect stored pumps for signs of moisture or physical damage, and ensure they are handled with care to avoid impacts that could misalign internal parts. When shipping, use protective packaging to shield the pump from vibrations and shocks, which can disrupt the delicate balance of the internal mechanisms. A well-organized storage system, with clear labeling and first-in-first-out rotation, helps prevent obsolescence and ensures that the pumps you install meet the highest standards of reliability.
