Bosch 0445110279 Hyundai/Kia 2.5 CRDi D4CB Common Rail Injector
Bosch CRI2 solenoid common-rail diesel injector for the Hyundai/Kia 2.5 CRDi D4CB engine, Bosch 0445110279, Hyundai/Kia OE 33800-4A000 (supersessions 33800-4A100 / 4A150 / 4A160 / 4A170). Fitted to the Hyundai H-1 / iLoad / i800 / Starex, Hyundai Terracan and Kia Sorento I (BL). Common failure drivers on these D4CB injectors are fuel contamination, nozzle coking and internal wear that raises back-leakage until the ECU can no longer compensate. Confirm the stamped Bosch number 0445110279 before ordering - the 2.5 D4CB injector is NOT interchangeable with the 2.2 CRDi D4HB/D4EB (33800-2F / 33800-27800), the 1.5 CRDi D4FA (0445110255) or the 1.4 CRDi D4FC (DFIR00203D) injectors. Key symptoms: Hard starting / extended cranking; Rough idle and vibration; Loss of power / limp mode; Black smoke. Common failure modes: Nozzle coking / poor atomisation; High back-leakage / internal wear; Corrosion from water in fuel.
High back-leakage from a worn injector drops cranking rail pressure on the D4CB, making the engine slow to start, especially when cold.
An out-of-balance injector unevenly fuels its cylinder, producing a shaky idle and audible misfire on the H-1/Sorento.
When injector delivery falls outside its correction range the ECU pulls fuel and boost or drops the vehicle into limp mode.
Poor atomisation from a worn nozzle over-fuels the cylinder, producing visible black smoke under load.
A leaking injector causes a pronounced top-end knock on the D4CB, often most obvious at idle.
Internal leakage and over-fuelling waste fuel and can trigger fuelling-related fault codes.
- codingEach Bosch injector carries an individual IMA/correction code that must be written into the ECU with a Hyundai/Kia-capable tool (GDS) after fitting; without coding the D4CB runs on default trim and may log cylinder-balance faults.
- InstallationReplace the fuel filter and check for water/debris before fitting - contaminated fuel is the leading cause of repeat failure on the D4CB.
- InstallationFit a new injector sealing washer and use the correct tightening torque; a reused or crushed washer causes combustion blow-by around the injector bore.
- MisdiagnosisRead live injector correction and back-leakage values to find the weak cylinder before removal rather than replacing all four injectors blind.
- WarningConfirm the stamped Bosch number 0445110279 before ordering - the 2.5 D4CB injector is NOT interchangeable with the 2.2 CRDi D4HB/D4EB or the 1.5/1.4 CRDi D4FA/D4FC injectors.
- TestingBench-test on a Bosch-capable common-rail tester (CR318-PRO or equivalent) across delivery and back-leakage points; verify spray pattern and cylinder balance before refitting.
What is Bosch injector 0445110279?+
A Bosch CRI2 solenoid common-rail diesel injector for the Hyundai/Kia 2.5 CRDi D4CB engine. Hyundai/Kia OE 33800-4A000 (supersessions 33800-4A100/4A150/4A160/4A170).
Which vehicles use 0445110279?+
Hyundai H-1 / iLoad / i800 / Starex, Hyundai Terracan and Kia Sorento I (BL) with the 2.5 CRDi D4CB engine.
Is it solenoid or piezo?+
It is a Bosch CRI2 solenoid common-rail injector.
What is the Hyundai/Kia OE number for 0445110279?+
33800-4A000, with supersessions 33800-4A100 / 4A150 / 4A160 / 4A170. Always confirm the number stamped on your original injector before ordering.
What are the symptoms of a failing 0445110279?+
Hard starting, rough idle and vibration, loss of power or limp mode, black smoke, diesel knock and higher fuel consumption.
Why does my Hyundai H-1 2.5 CRDi knock or rattle?+
A leaking injector causes a top-end knock on the D4CB that is often most obvious at idle. Bench-test to confirm the faulty cylinder before replacing.
What causes these injectors to fail?+
Fuel contamination, water in the fuel, nozzle coking and high-mileage internal wear that raises back-leakage - fix the cause, not just the injector.
Do I need to code the injector to the ECU?+
Yes. Each Bosch injector has an individual IMA correction code that must be written into the ECU with a Hyundai/Kia GDS tool after fitting, or the engine runs on default trim and may log cylinder-balance faults.
Is 0445110279 the same as the 2.2 CRDi injector?+
No. 0445110279 is the 2.5 D4CB injector; the 2.2 CRDi D4HB/D4EB use different injectors (33800-2F610 / 33800-27800). They are not interchangeable - match the stamped number.
Is 0445110279 the same as the 1.5 or 1.4 CRDi injector?+
No. The 1.5 CRDi D4FA (0445110255) and 1.4 CRDi D4FC (DFIR00203D) use different injectors. The 2.5 D4CB uses 0445110279 - confirm the stamped number.
Should I replace one or all four?+
Diagnose each with live correction and back-leakage values; on high-mileage D4CB engines failures often cluster, so check all four before deciding.
Does a remanufactured 0445110279 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated to the Bosch plan to meet original delivery and back-leakage specifications.
