Delphi EJBR03801D 2.0 HDi Common Rail Injector (Peugeot/Citroen DW10BTED4)

AI Technical Summary

Delphi EJBR03801D (OE 9656389980) common-rail injector for the PSA 2.0 HDi DW10 platform (RHA/RHR, 136hp). The DW10BTED4/CTED4 also shipped with Siemens VDO 5WS40156Z from factory — confirm the OEM markings on the injector body before fitting. Remanufactured, calibrated, 12-month warranty. Key symptoms: Rough idle / vibration; Hard starting; Loss of power / limp mode; Black smoke. Common failure modes: Internal wear / high back-leakage; Nozzle coking / poor spray pattern; Water-in-fuel corrosion.

Common Symptoms

Rough idle / vibrationhigh

A leaking or out-of-calibration injector unbalances cylinder fuelling, felt as a shake at idle.

Hard startinghigh

Excess back-leakage bleeds rail/line pressure during cranking, causing long or failed starts.

Loss of power / limp modehigh

Out-of-range delivery or pressure deviation triggers a torque cut and limp home.

Black smokemedium

Poor atomisation or a dribbling nozzle over-fuels the cylinder.

Engine management lightmedium

Cylinder-specific injector, balance or fuel-metering fault codes are logged.

Workshop & Fitting Notes

InstallationCode the Delphi C2I classification to the correct cylinder on fitment with PSA Lexia/PP2000 (or Ford IDS) before road test.
InstallationRenew the copper combustion washer and leak-off seals; torque the clamp/nut to manufacturer spec.
MisdiagnosisRead live back-leakage and per-cylinder contribution data to confirm the weak cylinder before removal.
TestingBench-test across delivery and back-leakage points and verify spray pattern before refit.
WarningConfirm fitment by OE number and engine code before ordering; injector sub-variants are not always interchangeable.

Frequently Asked Questions

What is injector EJBR03801D?+

EJBR03801D is a Delphi common rail solenoid injector diesel injector for the PSA 2.0 HDi (DW10BTED4 / RHR / RHA). It is supplied remanufactured, bench-tested and calibrated to OEM specification.

Which vehicles use EJBR03801D?+

It is fitted to the PSA 2.0 HDi (DW10BTED4 / RHR / RHA) — including Peugeot 307 2.0 HDi 136 (DW10BTED4); Peugeot 407 2.0 HDi 136 (DW10BTED4); Peugeot 807 2.0 HDi 136 (DW10BTED4); Citroen C4 2.0 HDi 136 (DW10BTED4). Confirm fitment by OE number and engine code.

What type of injector is EJBR03801D?+

It is a Delphi Common Rail Solenoid Injector. Always confirm the OEM markings on the injector body before fitting.

Does EJBR03801D need coding when fitted?+

Yes — write the Delphi C2I classification code to the correct cylinder on fitment using Lexia/PP2000 (PSA) or Ford IDS.

What are the symptoms of a failing EJBR03801D?+

Common signs are rough idle and vibration, hard starting, power loss or limp mode, black smoke and an engine-management light.

What causes these injectors to fail?+

Most failures come from poor fuel filtration, contamination and water in the fuel leading to wear, high back-leakage and nozzle coking. Fix the cause before fitting replacements.

Is a remanufactured EJBR03801D as good as new?+

A properly remanufactured injector is stripped, fitted with new wear parts, reassembled and recalibrated on a common-rail test bench to OEM tolerances, then supplied with a warranty.

Should I replace one injector or the full set?+

Replace the confirmed faulty injector first. On high-mileage engines fitting a matched set reduces the chance of a repeat fault, but it is not mandatory if the others test within spec.

Do you bench-test the injector before dispatch?+

Yes. Every unit is tested for delivery, back-leakage and spray pattern on a calibrated common-rail tester before it leaves us.

Is delivery and warranty included?+

Yes — the price includes free UK delivery and a 12-month warranty.

Is the DW10BTED4 a Delphi or Siemens injector?+

Both were fitted from factory: Delphi EJBR03801D and Siemens VDO 5WS40156Z. They are not interchangeable — read the OEM markings on the injector body before ordering.

What is the PSA OE number for EJBR03801D?+

PSA OE 9656389980 (also seen as 1980S3/1980K3); the Delphi equivalent is R03801D.
