Description
Bosch injector set for 1.6 eHDI 68 kW engines. Mileage: 64,000 km.
Product Description
This Bosch injector set (part number 0445110340) is designed for PSA 1.6 eHDI 68 kW diesel engines. Ideal for professional mechanics and experienced DIY enthusiasts performing engine service or repairs, the set is often searched by its product codes (0445110340, 1980S5, 1980S6). The injectors are a direct-fit solution for common-rail fuel systems used on a range of Citroën and Peugeot models, delivering precise fuel dosing to maintain efficient combustion and low emissions.
Compatibility
Typical compatible vehicles include (non-exhaustive):
- Citroën Berlingo B9
- Citroën C3 Picasso
- Citroën C4 II
- Citroën C4 Picasso
- Peugeot 301
- Peugeot 308
- Peugeot Partner Tepee
How It Works
These are high-pressure common-rail fuel injectors that meter and inject atomized diesel directly into the combustion chamber. Proper injector function is essential for smooth idling, consistent power delivery, fuel economy and to limit soot and unburned hydrocarbons that can stress the EGR and DPF systems.
When And Why Injectors Fail
- Fuel Contamination: Particles and water in fuel cause nozzle clogging and wear.
- Soot And Carbon Build-Up: Aggressive EGR/DPF duty cycles and poor combustion promote deposits that affect spray pattern.
- Electrical Or Seal Failure: Damaged connector pins, wiring or degraded O-rings lead to leaks or misfires.
- Fuel Quality And Maintenance: Low-quality diesel or extended intervals between fuel filter changes reduce injector life.
While service life varies with driving conditions and maintenance, injectors can fail prematurely if fuel system contamination or excessive soot accumulation occurs. The supplied set has recorded mileage of 64,000 km.
Replacement And Installation
Recommended for trained technicians or experienced DIY mechanics. Typical replacement steps (high-level):
- Work Safely: Park on level ground, depressurize the fuel system and wear eye protection and gloves.
- Disconnect Battery: Always disconnect the negative terminal before starting fuel system work.
- Relieve Fuel Pressure: Follow manufacturer procedure to relieve rail pressure before disconnecting lines.
- Access Injectors: Remove engine cover and ancillary components as required to reach the fuel rail and injectors.
- Disconnect Electrical Connectors: Label and remove injector connectors carefully.
- Remove Fuel Rail Retaining Bolts: Support the rail and remove slowly to avoid damage to rails or pipes.
- Extract Injectors: Remove securing clips and pull injectors straight out; some models require a special puller if seized.
- Fit New O-Rings And Seals: Always replace injector O-rings and seat seals; lubricate with clean diesel or assembly paste to prevent damage during installation.
- Reassemble And Torque To Spec: Refit rail and fasteners to manufacturer torque settings.
- Prime System And Check For Leaks: Repressurize the system, check for fuel leaks and correct rail pressure before starting the engine.
- Diagnostics: Clear any injector-related fault codes and verify smooth idle and proper fuel trim. If fault codes persist, check wiring, rail pressure sensor and pump.
Installation Recommendations
- Replace fuel filters when changing injectors to avoid recontamination.
- Inspect injector connectors and wiring harness for corrosion or damage and repair as needed.
- Use manufacturer torque values for rail and injector brackets; avoid over-tightening.
- Always fit new O-rings/seals and ensure they are correctly seated to prevent leaks.
- After installation, run the engine and inspect for leaks, then perform a road test to confirm correct operation.
Why This Part Is Searched By Code
Professional mechanics commonly search injectors by exact part numbers (0445110340, 1980S5, 1980S6, 445110340) to ensure correct fitment for PSA engines. Listing the OEM and cross-reference numbers in the product description helps speed up procurement and repair planning.
