Description
Bosch injector set for 1.6 eHDI 68 kW engines. The car ran normally and did not smoke even when cold. We also have sets with lower mileage in stock. Removed from a vehicle with an honest 182,000 km.
Overview
High-quality Bosch injector set designed for PSA 1.6 eHDI 68 kW diesel engines. These common-rail injectors deliver precise fuel metering and good atomization to maintain smooth idling, efficient combustion and stable cold starts. The unit is commonly searched by part number (e.g. 0445110340, 1980S5) — ideal for technicians and DIY mechanics looking for a direct replacement.
Compatibility
Suitable for a range of Citroën and Peugeot models equipped with the 1.6 e-HDi 68 kW engine, including but not limited to:
- Citroën Berlingo B9
- Citroën C3 Picasso
- Citroën C4 II
- Citroën C4 Picasso
- Peugeot 301
- Peugeot 308
- Peugeot Partner Tepee
How It Works And When To Replace
Injectors meter high-pressure fuel into the combustion chamber in a precise spray pattern. Over time they can lose performance due to mechanical wear, deposits or sealing deterioration, which leads to rough idle, misfires, increased consumption or smoke. Typical service life varies with fuel quality and driving conditions; many injectors remain serviceable beyond 150,000 km, while others may fail earlier. This particular set was removed at 182,000 km and was reported to run normally at removal.
Replacement Procedure (Summary)
Recommended steps for replacing the injector set:
- Relieve fuel pressure before starting and isolate the electrical system as appropriate.
- Remove engine covers and any components blocking access to the fuel rail.
- Disconnect injector electrical connectors and fuel lines from the rail (use correct fuel line tools to avoid damage).
- Remove the fuel rail mounting bolts and carefully extract the rail with injectors attached.
- Remove old injectors, replace all O-rings/seals and any crush washers.
- Lubricate new O-rings with clean engine oil, press injectors into the rail or cylinder head to correct fit, and torque fixings to manufacturer specifications.
- Reassemble, prime the fuel system (crank without starting or use the fuel pump priming procedure) and check for leaks. Start engine and verify smooth operation and absence of leaks.

Installation Recommendations
Always work in a clean environment to avoid contaminating injectors. Replace all O-rings and sealing components when fitting new injectors. Use the correct torque values and injector pull/press tools where required. After fitting, prime the fuel system and inspect for leaks at ambient pressure and under running conditions. If available, perform a diagnostic scan to check injector trim values and ensure the engine control unit has no related fault codes.
Most Common Failure Causes
Injectors commonly fail due to fuel contamination and deposits, wear of internal moving parts (needle and seat), electrical coil or connector faults, and degraded seals or O-rings causing leakage. Poor fuel quality, excessive idling, or long service intervals can accelerate deposit build-up and reduce injector life.
