What is injector 0445110339?
0445110339 is a Bosch common rail solenoid injector (cri2) diesel injector for the PSA / Ford 1.4 HDi / TDCi (DV4TD, 8HP/8HR). It is supplied remanufactured, bench-tested and calibrated to OEM specification.
Which vehicles use 0445110339?
It is fitted to the PSA / Ford 1.4 HDi / TDCi (DV4TD, 8HP/8HR) — including Peugeot 207 1.4 HDi 68 (8HP/8HR); Citroen C3 1.4 HDi 68 (8HP/8HR); Ford Fiesta VI 1.4 TDCi (KVJA); Mazda 2 (DE) 1.4 MZ-CD (8HP). Confirm fitment by OE number and engine code.
What type of injector is 0445110339?
It is a Bosch Common Rail Solenoid Injector (CRI2). Always confirm the OEM markings on the injector body before fitting.
Does 0445110339 need coding when fitted?
It is ECU-dependent — some DV4 applications require injector correction coding and some do not. Verify in Lexia/PP2000 (PSA) or Ford IDS and code where required.
What are the symptoms of a failing 0445110339?
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 0445110339 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.
Is 0445110339 the same as the Delphi 1.4 HDi injector?
No. The DV4 1.4 HDi was built with Bosch (8HP/8HR, this part), Delphi (DV4TED4, 8HY) and Siemens (8HZ) injectors. They are not interchangeable — match the OEM number on your injector.
Does 0445110339 need coding?
It is ECU-dependent. Some DV4 applications require injector correction coding via Lexia/PP2000 or Ford IDS; verify the requirement for your VIN on fitment.
