A2C59511603 — Technical Research
Continental (Siemens VDO) solenoid common-rail injector for the PSA 2.0 HDi (DW10BTED4) engine across Peugeot, Citroen and Ford applications. PSA OE 9656389980 / 1980K3; Delphi equivalent EJBR03801D; Bosch cross 0986438003. Replacements are coded to the ECU with the injector correction value. Failures are driven by poor fuel filtration, contamination and back-leakage. 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 2.0 HDi DW10.
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 injector correction value to the correct cylinder with PSA Lexia / Ford IDS before road test.
- InstallationRenew the copper combustion washer and leak-off seals; torque the clamp to spec.
- MisdiagnosisRead live back-leakage / cylinder-contribution data to find the weak cylinder before removal.
- WarningVerify the OE number (9656389980) and engine code - the DW10 family has several injector revisions across power outputs.
- TestingBench-test across delivery and back-leakage points; verify spray pattern before refit.
What is injector A2C59511603?+
A Continental (Siemens VDO) solenoid common-rail diesel injector for the PSA 2.0 HDi (DW10BTED4) engine in Peugeot, Citroen and Ford applications. PSA OE 9656389980; Delphi equivalent EJBR03801D.
Which vehicles use A2C59511603?+
Peugeot 307/407/607/807, Citroen C4/C5/C6/C8 2.0 HDi and Ford Galaxy/S-MAX/Mondeo 2.0 TDCi (DW10, market-specific).
Is it solenoid or piezo?+
It is a Continental/Siemens VDO solenoid common-rail injector.
Does A2C59511603 need coding?+
Yes - code the injector correction value to the correct cylinder with PSA Lexia / Ford IDS when fitting.
What are the OE part numbers?+
PSA 9656389980 and 1980K3/1980W6 reference this injector; the Delphi equivalent is EJBR03801D and the Bosch cross is 0986438003.
Is the Delphi EJBR03801D the same injector?+
It is the Delphi equivalent for the same DW10BTED4 2.0 HDi application - confirm the OE number and engine code before fitting.
What are the symptoms of failure?+
Rough idle, vibration, hard starting, black smoke, power loss/limp mode and an EML.
Why does my 2.0 HDi run rough?+
A worn or leaking injector unbalances fuelling; read live cylinder-contribution data and bench-test the suspect cylinder.
What causes these injectors to fail?+
Poor fuel filtration, contamination and back-leakage wear - fix the cause first.
Does a remanufactured A2C59511603 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated on a Continental-capable tester, then coded on fitment.
