Condition And Origin
Set removed from a Citroën C8 2.2 HDi 125 kW with 128,000 km. At the time of removal the vehicle started reliably in cold conditions, showed no visible exhaust smoke and had a clean DPF. The injectors were operating correctly in the donor vehicle.
Installation Recommendations
- Relieve fuel system pressure and disconnect the battery before starting work.
- Carefully remove the fuel rail and injectors; avoid contaminating the common-rail system.
- Always fit new injector O‑rings and sealing washers/copper crush washers when installing injectors.
- Clean injector bores and rails; ensure sealing surfaces are free of debris to prevent leaks.
- Use correct torque values for rail and injector hold‑down bolts (refer to factory workshop manual for exact figures).
- After installation, prime the fuel system and check for leaks. Start the engine and observe for leaks, rough running or fault codes.
- In many PSA common‑rail systems an injector adaptation/calibration with a diagnostic tool (DiagBox or equivalent) may be required to restore optimal fueling and idle quality. If available, perform injector coding/adaptation after installation.
- For best results, have installation performed or checked by a qualified technician familiar with Bosch common‑rail systems.
Why Injectors Commonly Fail
- Contaminated Fuel: Particles and deposits from poor fuel or a degraded fuel filter cause clogging and wear.
- Wear And Tear: High mileage and repeated thermal/corrosive stress reduce spray quality and sealing.
- Fuel System Issues: Faulty high‑pressure pumps or excessive return flow can overload injectors.
- Electrical Problems: Connector corrosion, wiring faults or driver issues in the ECU may lead to misfiring.
- Excessive Soot Or DPF Backpressure: Poor combustion and DPF problems increase contaminant load and stress the injectors.
Typical Symptoms Of Failing Injectors
- Rough Idle And Misfires
- Increased Fuel Consumption
- Hard Cold Starts Or No Start Condition
- Visible Smoke Under Acceleration
- Loss Of Power And Hesitation
- Engine Fault Codes Related To Misfire Or Injector Circuit
Notes For Buyers
This is a used set of Bosch injectors removed from a running Citroën C8 with 128,000 km. Part numbers listed above are widely used when searching for compatibility. Suitable for mechanics and experienced DIY customers comfortable with diesel fuel system work. Replace all seals during installation and consider injector adaptation for precise fueling.
