Continental/Siemens VDO A2C59511603 2.0 HDi (DW10BTED4) Common Rail Injector (Peugeot/Citroen/Ford)
AI Technical Summary
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.
Common Symptoms
Rough idle / vibrationhigh
A leaking injector unbalances cylinder fuelling on the 2.0 HDi DW10.
Hard startinghigh
Excess back-leakage drops cranking rail pressure.
Loss of power / limp modehigh
Out-of-range delivery or rail-pressure deviation cuts power.
Black smokemedium
Poor atomisation over-fuels the cylinder.
Engine management lightmedium
Cylinder-specific injector or fuel-metering codes.
Workshop & Fitting Notes
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.
Frequently Asked Questions
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.
A2C59511603 is the Continental / Siemens VDO injector built specifically for the PSA-only 2.0-litre HDi run that did not share Ford or Volvo supply — covering Peugeot 407 / 5008 / 807 / Expert and Citroen C5 / C8 / Dispatch / SpaceTourer applications fitted with engine codes prefixed 6DRH. It sits alongside the larger DW10 family but uses different bore tolerances and a PSA-specific connector keying. The procedure below is the bench-side workflow we apply before every A2C59511603 unit is dispatched.
How a Failing 6DRH Injector Presents
On the PSA-only 2.0 HDi run, a failing injector typically presents with cold-start hesitation that lasts 30 to 60 seconds longer than normal — the rail loses prime overnight while one cylinder bleeds fuel back through a worn seat. The second signature is a steady loss of pulling power above 2,500 rpm under load — the car simply will not push past 90 mph on a flat motorway. The third is intermittent EML triggered after long motorway runs where the ECU finally logs a P1351 / P1352 cylinder-imbalance code.
Because the 6DRH-coded engines are predominantly fitted to MPVs (807, 5008, C8, SpaceTourer), the failures are most visible to drivers who tow or carry heavy loads — the engine cannot mask the imbalance under load the way it can on light passenger-car duty.
Vehicles and Engine Codes Using the A2C59511603
Engine code coverage spans PSA 6DRHRH, 6DRHRE, 6DRHRG, 6DRHWB and selected RHV-series sub-codes used in PSA-only Euro 4 production. UK fitment includes Peugeot 407 / 407 SW / 5008 / 807; Citroen C5 / C5 Tourer / C8 / Dispatch / SpaceTourer; and a small number of Fiat Group rebadged Scudo / Ulysse 2.0 JTD vehicles fitted with the PSA-supplied DW10 engine.
A2C59511603 is closely related to the wider DW10 5WS40156Z family but is not interchangeable — the bore profile is matched to the PSA-only ECU calibration and the connector polarity is keyed differently. Confirm the OE marking on the unit you are removing before ordering across the two families.
IMA Coding the A2C59511603
Each A2C59511603 carries a sixteen-character IMA / IQA string printed on a foil label affixed to the top of the body. After fitting, the string must be programmed into the ECU on the correct cylinder index using PSA DiagBox / Lexia. Skipping the coding step will trigger an immediate P1351 / P1352 cylinder-imbalance code on first start.
The 6DRH ECU calibration is more sensitive to IMA accuracy than the broader DW10 calibration because it runs a tighter post-injection window for Euro 4 NOx targets. Read and enter the string carefully — a single character entered incorrectly will degrade fuel economy and reload the DPF.
How A2C59511603 Injectors Are Remanufactured
A2C59511603 cores come almost exclusively off MPV chassis (Peugeot 807 / 5008, Citroen C8 / SpaceTourer) and consequently arrive with above-average mileage — most cores we receive are at or beyond 150,000 miles. The remanufacture flow accommodates that by running an extra metallurgical inspection on the control-valve seat: at high mileages on this engine, the seat shows micro-pitting that does not show up in a standard flow test but reduces injector life by 30,000-40,000 miles after re-use. Cores that fail the metallurgical inspection are condemned rather than re-used, even if they pass the bench flow test.
Reassembly uses a Continental DW10-pattern seat plate adjusted for 6DRH-specific tolerance. Output is a fresh sixteen-character IMA string and a Euro-4-tightened calibration certificate retained on file. Warranty: 12 months parts, free UK delivery, refundable core surcharge.
Will A2C59511603 fit my Peugeot 407 / Citroen C5 / 807 / C8?
Yes — provided your car is fitted with the PSA-only 2.0 HDi engine using engine codes prefixed 6DRH (6DRHRH / 6DRHRE / 6DRHRG). The closely related DW10 (RHR / RHD / RHL) family uses a different injector primary (5WS40156Z) — confirm the OE marking on the failed unit before ordering across the two families.
Do I need to recode the IMA string?
Yes. The 6DRH ECU calibration is more sensitive to IMA accuracy than the broader DW10 — programming the IMA string into the ECU per cylinder using PSA DiagBox / Lexia is non-optional after fitting.
Why is this different to the wider DW10 5WS40156Z?
Both injectors come from the same Continental supply chain and share the same bench platform, but the bore profile and connector keying are different. The 6DRH-coded engines run a tighter post-injection window for Euro 4 NOx targets, which is why PSA specified a unit-specific calibration. They are not interchangeable.
No injector coding is required for the Siemens VDO / Continental unit on most applications — follow the manufacturer fitting procedure.
Replacement Advice
Always renew the copper washers / seals and bleed the fuel system before first start. Replace only the injectors your diagnosis confirms and torque fasteners to the manufacturer's published values.
Professional Installation
We recommend installation by a suitably equipped diesel specialist using calibrated test equipment to verify the fuel system after fitting.
If your vehicle shows these symptoms, replacing the diesel injector may restore engine performance. A leak-off test can confirm the diagnosis.
