Verified answers about the Continental/VDO A2C9303500080 2.0 EcoBlue Common Rail Injector (Ford Transit).
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.
