About this category
The 2.2 HDi 130 hp diesel engine, widely used in commercial and passenger vehicles from the mid-2000s, relies on a high-pressure pump to inject fuel into the combustion chamber at pressures exceeding 2,000 bar. This category covers remanufactured high-pressure pumps designed for exchange standard applications, addressing common failures such as inconsistent fuel delivery, hard starting, or excessive smoke. Whether you are a professional mechanic or a DIY enthusiast, finding a compatible replacement is essential to avoid prolonged vehicle downtime.
This range is built around two industry-standard remanufactured models: the DENSO 294000-040X and the SIEMENS-VDO 5WS40694, both engineered to match the original specifications of the 2.2 HDi 130 hp engine. These pumps are sourced from suppliers who specialize in diesel fuel system components, ensuring compatibility and reliability for bulk orders and individual replacements alike.
Professional uses by trade
Different users approach the high-pressure pump replacement with distinct priorities: garages prioritize bulk availability and fast turnaround, while DIY enthusiasts seek clear compatibility and straightforward installation. Professionals and private owners alike benefit from understanding the symptoms of pump failure and the exchange process.
- Le garagiste independant : Replaces the high-pressure pump during scheduled maintenance to prevent unexpected breakdowns, using remanufactured units to reduce costs without compromising performance.
- L'automobiliste depanne : Diagnoses a failing pump when the engine stalls or emits excessive smoke, opting for an exchange standard unit to restore drivability quickly.
- Le passionne qui fait lui-meme : Installs a remanufactured high-pressure pump after confirming compatibility with the vehicle’s engine code, following technical documentation for precise fitting.
- Der deutsche Kaeufer (DACH) : Seeks a reliable high-pressure pump for the 2.2 HDi 130 hp engine, prioritizing compatibility with local vehicle models and adherence to European emission standards.
- Le garagiste independant : Orders multiple high-pressure pumps in bulk to stock inventory, ensuring immediate availability for customers with 2.2 HDi engines requiring urgent repairs.
- L'automobiliste depanne : Purchases an exchange standard pump after receiving a diagnostic report from a mechanic, focusing on cost-effective solutions for high-pressure system failures.
- Der deutsche Kaeufer (DACH) : Verifies the pump’s compatibility with the vehicle’s model year and engine variant before purchase, avoiding mismatches in fuel system components.

| High-pressure pump SIEMENS-VDO 5WS40694 | Compatible with PSA 2.2 HDi 130 hp variants |
How to choose
Selecting the right high-pressure pump involves evaluating several factors, including compatibility with the engine code, the condition of the unit, and the supplier’s return policy for core deposits.
- Verify the engine code (e.g., DW12B) stamped on the original pump to ensure the replacement matches the vehicle’s specifications exactly.
- Inspect the remanufactured pump for visible damage or wear, such as cracked housings or corroded connectors, which could indicate poor refurbishment quality.
- Check the supplier’s core deposit policy, as returning the old pump is often required to complete the exchange and avoid additional fees.
- Prioritize pumps with a documented remanufacturing process, including pressure testing and seal replacement, to ensure consistent performance.
- Confirm the pump’s compatibility with the vehicle’s model year and emission standards, especially for models sold in the DACH region.
- Assess the packaging quality, as improper storage or transit can damage sensitive components like the pump’s internal gears or sensors.
- Request a warranty or deliver of functionality from the supplier, though this should not be framed as a promise but rather as a standard industry practice.
Storage & logistics
For garages and wholesalers, storing high-pressure pumps requires climate-controlled environments to prevent moisture damage and corrosion, with units kept in sealed packaging until installation. Regular inventory rotation ensures older stock is used first, reducing the risk of degradation over time. Suppliers should also provide clear handling instructions to avoid accidental damage during transit or storage, as even minor impacts can compromise the pump’s internal components and lead to premature failure.
With over a decade of experience in diesel fuel system components, our team has seen how a failing high-pressure pump can cripple a 2.2 HDi engine, which is why we source only remanufactured units that meet the original equipment’s performance benchmarks.— autoKUR team
