Which engines use the Delphi EJDR01101D injector?

EJDR01101D is verified for the 2.4L TDCi platform, covering engine code H9FA. Confirm the engine code on your V5C before ordering.

Which vehicles does EJDR01101D fit?

This family has 1 verified fitment across Ford — the full registry-verified list is on this page.

My injector is etched with a different number — is it the same part?

EJDR01101D cross-references R01101D, HRD331, R00403Z, EJDR00403Z, 4C1Q9K546AB and 4C1Q-9K546-AB among others. If your etched number appears in this family's reference list it is a verified equivalent; if not, send us a photo of the etching and we will confirm before you order.

Do I need to code the replacement injector to the ECU?

Yes on common-rail diesels. Every injector ships with an individual calibration code that must be written to the ECU after fitting, following the manufacturer procedure — without it the engine runs on default trims and can log cylinder-balance faults.

How is each injector tested before despatch?

Every unit is bench-calibrated against the manufacturer specification — delivery, back-leak and response verified — and despatched with a 12-month parts warranty and its calibration data retained on file.

Common failure symptoms

On the 2.4L TDCi platform, a failing Delphi EJDR01101D injector typically presents as: hard starting or extended cranking; rough or uneven idle; loss of power under load; excess smoke from the exhaust; cylinder misfire or contribution fault codes.

When two or more of these appear together, suspect the injector before peripheral systems — a comparative leak-off test and live-data cylinder-balance review will isolate the failed unit without tear-down.

When two or more symptoms appear together, suspect the injector before peripherals (EGR, glow plugs, turbo). A live-data leak-off test on each cylinder is the fastest route to the failed unit.

What Causes These Injectors To Fail

The documented failure modes on this platform are: injector back-leak beyond specification; nozzle wear degrading the spray pattern; combustion gas leaks past the injector seat washer.

Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.

How Workshops Diagnose EJDR01101D Faults

Run a comparative leak-off (back-leak) test across all injectors before condemning a single unit. Compare requested vs actual rail pressure in live data at idle and under load. Inspect injector connectors and wiring before replacing hardware.

Never condemn a common-rail injector on a fault code alone — codes identify the circuit or cylinder, while leak-off volumes and correction values identify the component.

How Every Unit Is Tested Before Despatch

Each remanufactured EJDR01101D is fully stripped, ultrasonically cleaned and inspected; worn components are replaced with OE-grade parts. The rebuilt unit is then calibrated on a common-rail test bench against the manufacturer's specification sheet — delivery, back-leak and response are all verified before the injector is sealed and despatched with its calibration data on file.

Every unit carries a 12-month parts warranty and free UK delivery.

OE & Cross-References

EJDR01101D supersedes or cross-references 8 further OE numbers, including R01101D, HRD331, R00403Z, EJDR00403Z, 4C1Q9K546AB, 4C1Q-9K546-AB, 4C1Q9K546BA and 4C1Q-9K546-BA. Always match the reference etched on your failed unit's body — cross-references within a family are verified equivalents, but etched numbers remain the source of truth.
