A2C9303500080 — Technical Research
Continental/Siemens VDO solenoid common-rail injector for the Ford 2.0 EcoBlue (and PSA 2.0 BlueHDi / Fiat 2.0 MultiJet siblings). Fitted across Transit, Transit Custom, Ranger, Focus, Kuga and more. EcoBlue injectors are calibration-specific: a replacement must be coded to the ECU with its IQA/correction code via Ford IDS/FDRS, and failures are commonly driven by poor fuel filtration, contamination and back-leakage. Key symptoms: Rough idle / vibration; Hard starting / long crank; Limp mode / loss of power; Black smoke. Common failure modes: Internal wear / high back-leakage; Water-in-fuel corrosion; Nozzle coking / poor spray.
Continental/VDO A2C9303500080 2.0 EcoBlue Common Rail Injector (Ford Transit)
Continental/Siemens VDO solenoid common-rail injector for the Ford 2.0 EcoBlue (and PSA 2.0 BlueHDi / Fiat 2.0 MultiJet siblings). Fitted across Transit, Transit Custom, Ranger, Focus, Kuga and more. EcoBlue injectors are calibration-specific: a replacement must be coded to the ECU with its IQA/correction code via Ford IDS/FDRS, and failures are commonly driven by poor fuel filtration, contamination and back-leakage. Key symptoms: Rough idle / vibration; Hard starting / long crank; Limp mode / loss of power; Black smoke. Common failure modes: Internal wear / high back-leakage; Water-in-fuel corrosion; Nozzle coking / poor spray.
A leaking or out-of-calibration EcoBlue injector unbalances cylinder fuelling, giving a shaky idle.
Excess injector back-leakage bleeds rail pressure, so the engine cranks longer before firing.
Out-of-range injector delivery or rail-pressure deviation triggers reduced power on the EcoBlue.
Poor atomisation from a worn or coked nozzle over-fuels the cylinder.
Cylinder-specific injector, rail-pressure or fuel-metering fault codes.
A failing nozzle or seat causes an audible knock that varies with the weak cylinder.
- InstallationEcoBlue injectors are calibration-coded: program each new/reman injector's IQA/correction code to the correct cylinder with Ford IDS/FDRS or equivalent before road test.
- InstallationAlways renew the copper combustion washer and the injector clamp bolt, and torque to spec - reused seals and over-torque are common comebacks.
- MisdiagnosisRead live injector correction / back-leakage data to identify the weak cylinder before removal rather than replacing the full set blind.
- WarningFix the contamination source (filter, water, debris) first - water-in-fuel corrosion will destroy new injectors quickly.
- TestingBench-test on a Continental/Bosch-capable common-rail tester across delivery and back-leakage points; verify the spray pattern and cylinder balance.
What is injector A2C9303500080?+
A Continental/Siemens VDO solenoid common-rail diesel injector for the Ford 2.0 EcoBlue engine, also used on PSA 2.0 BlueHDi and Fiat 2.0 MultiJet vans.
Which vehicles use A2C9303500080?+
Ford Transit, Transit Custom, Tourneo Custom, Ranger, Transit Connect/Courier, Focus, Kuga, Mondeo, plus Peugeot Boxer, Citroen Relay and Fiat Ducato 2.0 diesel.
What are the Ford part numbers for this injector?+
Ford service numbers include GK2Q-9K546-AB/AC/AD, FB3Q-9B395-AB and JB3Q-9K546-AA, all referencing the Continental A2C9303500080 EcoBlue injector.
Is it solenoid or piezo?+
It is a Continental solenoid common-rail injector.
Does an EcoBlue injector need coding?+
Yes. EcoBlue injectors are calibration-specific - the IQA/correction code must be written to the ECU for the correct cylinder with Ford IDS/FDRS (or equivalent) when fitting.
What are the symptoms of a failing A2C9303500080?+
Rough idle, vibration, hard starting, black smoke, loss of power or limp mode, a diesel knock and an engine-management light.
Why does my 2.0 EcoBlue Transit run rough or go into limp mode?+
A leaking or out-of-calibration injector unbalances fuelling. Read live correction and back-leakage data to confirm the faulty cylinder before replacing.
What makes these injectors fail?+
Mainly poor fuel filtration, fuel contamination (including water) and back-leakage wear - so fix the cause, not just the injector.
Should I replace one injector or all four?+
Diagnose each with live data and a bench test. On high-mileage EcoBlue engines failures often cluster, so inspect all four before deciding.
Do I need to renew the copper washer?+
Yes - the combustion washer is a one-use crush seal. Reusing it causes blow-by and carbon build-up around the injector.
Does a remanufactured A2C9303500080 perform like new?+
A properly remanufactured EcoBlue injector is bench-tested and recalibrated to meet original delivery and back-leakage specs, then coded to the vehicle on fitment.
Will one injector fit Transit, Ranger and Boxer?+
The same Continental injector family is shared across Ford 2.0 EcoBlue and PSA 2.0 BlueHDi vans, but always confirm the exact engine code and Ford/PSA part number for your VIN.
