Description
Set of Bosch 2.0 HDi injectors for Citroën, Ford, Peugeot. The set comes from a 2018 Citroën C4 Spacetourer 2.0 HDi 120 kW with 141,000 km. The vehicle was running perfectly. Clean DPF.
High-quality Bosch common-rail injectors removed from a running 2.0 HDi engine. This complete injector set is ideal for professional workshops and technically skilled DIY mechanics who need reliable replacement parts to restore engine performance, reduce smoke and rough running, and maintain fuel economy. The units are original Bosch components and are often searched by their product numbers, making it easy to find the correct part for PSA group diesel engines.

Function And Benefits
Injectors meter and atomize diesel fuel into the combustion chamber at precise timing and pressure. Properly functioning injectors deliver even spray patterns for optimal combustion, cleaner emissions and stable idling. Replacing worn or leaking injectors restores engine smoothness, reduces visible smoke, and improves fuel consumption.
How To Replace
- Safety First: Work in a well-ventilated area. Relieve fuel pressure and disconnect the negative battery terminal before starting.
- Access: Remove engine cover and any components blocking access to the high-pressure fuel rail.
- Electrical Disconnect: Unplug injector electrical connectors and label them if necessary.
- Fuel Rail Removal: Loosen and remove the high-pressure fuel rail retaining bolts. Carefully lift the rail with injectors attached.
- Injector Removal: Use the correct tools or extractor to remove injectors without damaging cylinder head seats. Replace all injector seals and O-rings with new, OEM-quality seals.
- Installation: Fit new seals, install injectors into the rail or cylinder head, torque fasteners to manufacturer specification (refer to workshop manual), and reconnect electrical plugs.
- Commissioning: Prime the fuel system, check for leaks, start the engine and monitor for faults. Some vehicles may require injector adaptation or basic settings to be performed with diagnostic equipment.
Installation Recommendations
- Always Replace Seals: Replace all injector seals and copper crush washers to prevent leaks.
- Use Correct Tools: Avoid prying or levering injectors; use proper extractors to prevent damage to injector bores.
- Follow Manufacturer Procedures: Consult the vehicle workshop manual for torque values and sequence.
- Bleed And Test: After installation, bleed the system and perform a leak and performance check at idle and load.
- Diagnostic Check: Clear any stored fault codes and monitor live parameters to confirm correct injector operation.
Why This Part Commonly Fails
Diesel injectors are subject to high pressures and extreme thermal cycles. Common failure causes include fuel contamination (water, dirt, varnish), wear of internal components, leaking seals, and electrical connector faults. Symptoms of failing injectors include rough idle, misfires, hard starting, increased smoke or fuel consumption, and illuminated engine management warnings. Lifespan depends on fuel quality and maintenance; failures often occur after 100,000–200,000 km in poorly maintained systems.
Notes For Professionals
This injector set was removed from a running vehicle and is provided as a used OEM component. Mileage and provenance are stated to help evaluation. Ensure cleaning of the injector seats and confirm rail and fuel system condition before reinstallation to maximize service life.
Additional Items To Consider
- Replace Fuel Filter And Check Fuel Lines If Contamination Is Suspected
- Inspect High-Pressure Pump And Rail For Wear Or Leaks
- Consider Professional Ultrasonic Cleaning/Testing If Reusing Injectors
