A leaking or out-of-calibration injector unbalances cylinder fuelling, felt as a shake at idle.
Excess back-leakage bleeds rail/line pressure during cranking, causing long or failed starts.
Out-of-range delivery or pressure deviation triggers a torque cut and limp home.
Poor atomisation or a dribbling nozzle over-fuels the cylinder.
Cylinder-specific injector, balance or fuel-metering fault codes are logged.
- InstallationWrite the Bosch IMA/injector-correction code to the correct cylinder on fitment with Hyundai/Kia GDS/KDS before road test.
- InstallationRenew the copper combustion washer and leak-off seals; torque the clamp/nut to manufacturer spec.
- MisdiagnosisRead live back-leakage and per-cylinder contribution data to confirm the weak cylinder before removal.
- TestingBench-test across delivery and back-leakage points and verify spray pattern before refit.
- WarningConfirm fitment by OE number and engine code before ordering; injector sub-variants are not always interchangeable.
What is injector 0445110320?+
0445110320 is a Bosch common rail solenoid injector (cri2) diesel injector for the Hyundai / Kia 1.6 CRDi (D4FB / U2). It is supplied remanufactured, bench-tested and calibrated to OEM specification.
Which vehicles use 0445110320?+
It is fitted to the Hyundai / Kia 1.6 CRDi (D4FB / U2) — including Hyundai i30 (FD/GD) 1.6 CRDi (D4FB); Hyundai ix35 (LM) 1.6 CRDi (D4FB); Kia Cee'd (ED/JD) 1.6 CRDi (D4FB); Kia Sportage (SL) 1.6 CRDi (D4FB). Confirm fitment by OE number and engine code.
What type of injector is 0445110320?+
It is a Bosch Common Rail Solenoid Injector (CRI2). Always confirm the OEM markings on the injector body before fitting.
Does 0445110320 need coding when fitted?+
Yes — the Bosch IMA correction code must be written to the correct cylinder on fitment using Hyundai/Kia GDS/KDS.
What are the symptoms of a failing 0445110320?+
Common signs are rough idle and vibration, hard starting, power loss or limp mode, black smoke and an engine-management light.
What causes these injectors to fail?+
Most failures come from poor fuel filtration, contamination and water in the fuel leading to wear, high back-leakage and nozzle coking. Fix the cause before fitting replacements.
Is a remanufactured 0445110320 as good as new?+
A properly remanufactured injector is stripped, fitted with new wear parts, reassembled and recalibrated on a common-rail test bench to OEM tolerances, then supplied with a warranty.
Should I replace one injector or the full set?+
Replace the confirmed faulty injector first. On high-mileage engines fitting a matched set reduces the chance of a repeat fault, but it is not mandatory if the others test within spec.
Do you bench-test the injector before dispatch?+
Yes. Every unit is tested for delivery, back-leakage and spray pattern on a calibrated common-rail tester before it leaves us.
Is delivery and warranty included?+
Yes — the price includes free UK delivery and a 12-month warranty.
Does 0445110320 need IMA coding?+
Yes — the Bosch IMA code on the injector head must be entered against the correct cylinder using GDS/KDS on fitment.
How is the 1.6 CRDi D4FB injector different from the 1.7 D4FD?+
They are different Bosch part numbers for different engine sizes (1.6 D4FB vs 1.7 D4FD) and are not interchangeable. Match the OE number stamped on your part.
