Engine Intelligence
Renault 1.9 dCi (F9Q — Mégane, Scénic, Laguna, Trafic) F9Q816
Common symptoms
- Hard starting or extended cranking
- Rough idle and hesitation
- Loss of power / limp mode
- Black smoke under acceleration
- Random misfire entries
Documented failure modes
- Injector back-leak beyond specification causing rail-pressure loss
- Nozzle wear causing over-fuelling and smoke
- Fuel contamination damage following HP pump wear
Diagnostic guidance
- Run a leak-off comparison across all four injectors before condemning one
- If the HP pump has failed, flush the complete fuel system before fitting replacement injectors
- Replace the fuel filter and bleed the system fully after any injector work
Fitment note: The F9Q family spans many outputs and injector references across Renault, Vauxhall and Volvo applications — match the 0445110 number etched on the injector body.
Why this injector?
- Fits the F9Q816 engine code used in the Renault Megane and related diesel variants.
- Bosch diesel injector — flow-tested and calibrated on common-rail equipment before despatch.
- Commonly specified when investigating rough idle, injector knock, smoke or poor fuel economy on F9Q816 engines.
- 12-month warranty, free UK delivery and a £20 refundable core deposit per injector (refunded after we receive and inspect your old unit — return it within 30 days).
Bosch 0445110280 1.9 dCi (F9Q) Common Rail Injector (Renault Megane II / Scenic II / Laguna II)
Bosch CRI2 solenoid common-rail injector for the Renault 1.9 dCi (engine F9Q, ~96 kW / 131 hp) fitted to the Megane II, Scenic II / Grand Scenic II and Laguna II from 2005-2008. Renault OE 8200389369 / 8200535108 / 8200606383; Bosch exchange 0986435192. This is the later CRI2 generation - distinct from the early first-generation CRI1 0445110146 (Trafic/Master). Confirm the coding/correction procedure in Renault CLIP for the exact ECU. Failures are driven by poor fuel filtration, contamination and back-leakage wear. Key symptoms: Rough idle / vibration; Hard starting; Loss of power / limp mode; Black smoke. Common failure modes: Internal wear / high back-leakage; Water-in-fuel corrosion; Nozzle coking.
A leaking injector unbalances cylinder fuelling on the 1.9 dCi.
Excess back-leakage drops cranking rail pressure.
Out-of-range delivery or rail-pressure deviation cuts power.
Poor atomisation over-fuels the cylinder.
Cylinder-specific injector or fuel-metering codes.
- InstallationConfirm the injector correction/coding procedure in Renault CLIP for the exact ECU before road test.
- InstallationRenew the combustion seal and clamp hardware; torque to spec.
- MisdiagnosisRead live back-leakage data to find the weak cylinder before removal.
- WarningFix contamination (filter/water/debris) first; the 1.9 dCi is sensitive to fuel quality.
- TestingBench-test across delivery and back-leakage points; verify spray pattern before refit.
