0445110064 — Technical Research
Bosch CRI solenoid common-rail diesel injector for the Hyundai/Kia 2.0 CRDi D4EA engine, Bosch 0445110064, Hyundai/Kia OE 33800-27010 (laser-etched and OCR-confirmed on the part). Fitted to the Hyundai Santa Fe (SM/CM), Trajet, Tucson (JM) and Elantra (XD), and the Kia Sportage (JE/KM), Carens and Cerato with the first-generation 2.0 CRDi D4EA engine. Bosch 0445110101 is the same-family D4EA alternate (interchangeable supersession). Common failure drivers on these D4EA 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 0445110064 (OE 33800-27010) before ordering - the 2.0 D4EA injector is NOT interchangeable with the 2.5 CRDi D4CB (0445110279 / 33800-4A000), the 2.2 CRDi D4HB/D4EB (0445110583 / 33800-2F) or the 1.5 CRDi D4FA (0445110255) 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 D4EA, 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 Santa Fe / Tucson / Sportage.
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 D4EA, 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 D4EA 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 D4EA.
- InstallationFit a new injector sealing/copper 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 0445110064 (OE 33800-27010) before ordering - the 2.0 D4EA injector is NOT interchangeable with the 2.5 D4CB, 2.2 D4HB/D4EB or 1.5 D4FA 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 0445110064?+
A Bosch solenoid common-rail diesel injector for the Hyundai/Kia 2.0 CRDi D4EA engine. Hyundai/Kia OE 33800-27010 (related 33800-27000 / 33800-27900).
Which vehicles use 0445110064?+
Hyundai Santa Fe (SM/CM), Trajet, Tucson (JM) and Elantra (XD), and Kia Sportage (JE/KM), Carens and Cerato with the 2.0 CRDi D4EA engine.
Is it solenoid or piezo?+
It is a Bosch solenoid common-rail injector (CRI type).
What is the Hyundai/Kia OE number for 0445110064?+
33800-27010 (related 33800-27000 / 33800-27900). Always confirm the number stamped on your original injector before ordering.
Is 0445110101 the same injector as 0445110064?+
Yes. Bosch 0445110101 is the same-family D4EA alternate / supersession and is interchangeable with 0445110064. Match the stamped Bosch number when ordering.
What are the symptoms of a failing 0445110064?+
Hard starting, rough idle and vibration, loss of power or limp mode, black smoke, diesel knock and higher fuel consumption.
Why does my Hyundai Santa Fe 2.0 CRDi knock or rattle?+
A leaking injector causes a top-end knock on the D4EA 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 0445110064 the same as the 2.5 CRDi injector?+
No. 0445110064 is the 2.0 D4EA injector; the 2.5 CRDi D4CB uses 0445110279 (33800-4A000). They are not interchangeable - match the stamped number.
Is 0445110064 the same as the 2.2 or 1.5 CRDi injector?+
No. The 2.2 CRDi D4HB (0445110583) and 1.5 CRDi D4FA (0445110255) use different injectors. The 2.0 D4EA uses 0445110064 / 0445110101 - confirm the stamped number.
Should I replace one or all four?+
Diagnose each with live correction and back-leakage values; on high-mileage D4EA engines failures often cluster, so check all four before deciding.
Does a remanufactured 0445110064 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated to the Bosch plan to meet original delivery and back-leakage specifications.
