Description
Overview
Bosch fuel injector for 2.0 HDI diesel engines used across PSA Citroën and Peugeot models. Recognised under part numbers such as 0445110044, 9637536080 and 198093, this injector is a direct-fit option for many 8‑valve 2.0 HDI engines (engine codes RHY, RHS, RHZ, RHV).
Key Features
- Accurate fuel metering and fine atomization to support efficient combustion and stable idling.
- Direct compatibility with common PSA part numbers for straightforward replacement.
- Sold individually; the price is for one injector.
- All injectors are tested before sale.
Function And Failure Modes
Injectors meter and atomize diesel into the combustion chamber. Over time they can degrade due to contamination, nozzle wear, leaking seals, stuck/open valves or electrical failures. Poor fuel quality, long service intervals and high mileage increase the likelihood of faults.
Replacement Guidance
Replacement should be performed by a qualified technician. Typical procedure:
- Relieve fuel system pressure and disconnect the vehicle battery.
- Remove engine covers and fuel rail to access injectors.
- Unplug electrical connectors and remove injector retainers, then extract the injector carefully.
- Replace injector seals (O-rings) with new parts, install the new injector, reassemble the fuel rail and connectors.
- Prime the fuel system, check for leaks and run the vehicle to confirm correct operation; perform injector coding/adaptation if required by the vehicle diagnostics.
Service Life
Injector lifespan varies with driving conditions, maintenance and fuel quality. Many diesel injectors remain serviceable beyond 150,000 km, but symptoms such as rough idle, increased fuel consumption, smoke or misfires indicate evaluation or replacement is needed.
