0445110955 — Technical Research
Bosch solenoid common-rail injector for the PSA 1.5 BlueHDi (DV5RC) and Ford 1.5 EcoBlue engines, fitted across Citroen Berlingo/C3/C4, DS3/DS7 and Ford EcoSport/Fiesta. PSA OE 9820403480 / 9828959880; Ford JX6Q-9F593-AA. Failures are driven by poor filtration, contamination and back-leakage; a replacement is coded to the ECU via its IQA correction value. 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 1.5 BlueHDi.
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.
- InstallationCode the IQA/correction value to the correct cylinder with PSA Diagbox or Ford IDS/FDRS.
- InstallationRenew the combustion seal and clamp hardware and torque to spec.
- MisdiagnosisRead live correction/back-leakage data to find the weak cylinder before removal.
- WarningFix contamination (filter/water/debris) first to protect the new injector.
- TestingBench-test across delivery and back-leakage points; verify spray pattern.
What is Bosch injector 0445110955?+
A Bosch solenoid common-rail diesel injector for the PSA 1.5 BlueHDi and Ford 1.5 EcoBlue engines. PSA OE 9820403480/9828959880; Ford JX6Q-9F593-AA.
Which vehicles use 0445110955?+
Citroen Berlingo/C3/C4/Jumpy, DS3/DS7 Crossback, Peugeot 208/2008/308 and Ford EcoSport 1.5 diesel.
Is it solenoid or piezo?+
It is a Bosch solenoid common-rail injector.
What are the PSA part numbers?+
PSA OE numbers include 9820403480 and 9828959880; the Ford service number is JX6Q-9F593-AA.
Does it need coding?+
Yes - code the IQA/correction value with PSA Diagbox or Ford FDRS when fitting.
What are the symptoms of failure?+
Rough idle, vibration, hard starting, black smoke, power loss/limp mode and an EML.
Why does my 1.5 BlueHDi run rough?+
A worn or leaking injector unbalances fuelling; read live correction data and bench-test the cylinder.
What causes these injectors to fail?+
Poor filtration, contamination and back-leakage wear - fix the cause first.
Do I need to renew the seals?+
Yes - renew the combustion seal and clamp hardware; reused seals cause blow-by.
Does a remanufactured 0445110955 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated to the Bosch plan, then coded on fitment.
