Description
Bosch injection pump for Citroen, Peugeot, Opel, Fiat vehicles. For 1.5 HDi engines. Removed from a car with 48,000 km.
This high-pressure injection pump from Bosch is designed for 1.5 HDi diesel engines fitted to a range of Stellantis models. It is a direct replacement option for workshops and experienced DIYers who look for a reliable pump with known part numbers. The unit is suitable for vehicles where the listed part numbers match the original equipment reference and is aimed at restoring correct fuel pressure, injection timing and engine response on affected diesel engines.
Common symptoms indicating a failing injection pump include hard starting, loss of power under load, rough idling, increased smoke or fuel smell, poor acceleration and inconsistent fuel consumption. Replacing the pump often resolves misfires, low compression indications related to fuel delivery and irregular idle behavior.
Typical replacement steps (general guidance):
- Disconnect the vehicle battery and relieve fuel system pressure before any work.
- Remove intake components and any necessary engine covers to gain access to the pump.
- Mark the pump and engine timing positions to preserve injection timing; incorrect timing can damage the engine or cause poor running.
- Carefully disconnect electrical connectors and fuel lines (cap the lines to prevent contamination and spillage).
- Unbolt the pump from its bracket and remove it, keeping fasteners and spacers in order.
- Install the replacement unit aligning timing marks, replace all sealing washers and gaskets, reconnect fuel lines and electrical connectors.
- Prime and bleed the fuel system according to manufacturer procedure, reconnect the battery and verify there are no leaks. Start the engine and check for correct idle and absence of fault codes.
Installation Recommendations
Installation should be performed by a qualified mechanic or an experienced DIYer with diesel system knowledge. Always use clean diesel and replace the fuel filter when fitting a new pump. Replace all crush washers and high-pressure line seals to prevent leaks. Preserve and correctly set injection timing marks; if unsure, consult a workshop manual for the specific engine variant. After installation, check for fuel leaks and clear any stored fault codes with a diagnostic tool.
Why This Part Most Often Fails
High-pressure fuel pumps on diesel engines commonly fail due to fuel contamination (water, dirt or varnish), poor fuel quality, air ingress, or wear of internal components over time. Faulty seals or damaged high-pressure connections can cause external leaks. Irregular maintenance, clogged fuel filters and extended idling under poor conditions accelerate wear. In some cases, electronic actuator or sensor faults on modern pumps cause erratic behavior.
