0445110248 — Technical Research
Bosch solenoid common-rail injector for the Iveco/Fiat 3.0-litre diesel (engine F1CE0481) fitted to the Fiat Ducato 3.0 JTD, Iveco Daily 3.0 and Peugeot Boxer / Citroen Relay 3.0 HDi. Iveco/Fiat OE 504088823. A Bosch IMA/trim code is written to the ECU on fitment. The F1C is sensitive to fuel filtration; failures are driven by 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 F1C 3.0.
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.
- InstallationWrite the Bosch IMA/trim code to the correct cylinder with the dealer diagnostic tool 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.
- WarningConfirm the OE number 504088823 stamped on the old injector; the F1C 3.0 is sensitive to fuel quality - fix contamination first.
- TestingBench-test on a Bosch-capable CR tester across delivery and back-leakage points before refit.
What is Bosch injector 0445110248?+
A Bosch solenoid common-rail diesel injector for the Iveco/Fiat 3.0 diesel (F1CE0481). Iveco/Fiat OE 504088823.
Which vehicles use 0445110248?+
Fiat Ducato 3.0 JTD, Iveco Daily 3.0 and Peugeot Boxer / Citroen Relay 3.0 HDi, roughly 2006-2011.
Is it solenoid or piezo?+
It is a Bosch solenoid common-rail injector.
Does 0445110248 need coding?+
Yes - write the Bosch IMA/trim code to the correct cylinder with the dealer diagnostic tool when fitting.
What is the OE part number?+
Iveco/Fiat 504088823 references Bosch 0445110248.
Does it fit the 2.3 JTD Ducato?+
No - the 2.3 JTD uses a different injector. The 3.0 JTD/HDi (F1CE0481) uses 0445110248; confirm the OE number stamped on your injector.
What are the symptoms of failure?+
Rough idle, vibration, hard starting, black smoke, power loss/limp mode and an EML.
Why does my 3.0 JTD run rough?+
A worn or leaking injector unbalances fuelling; read live back-leakage data and bench-test the weak cylinder.
What causes these injectors to fail?+
Poor fuel filtration, contamination and back-leakage wear - fix the cause first.
Does a remanufactured 0445110248 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated to the Bosch plan, then IMA-coded on fitment.
