Delphi EJDR00601D Diesel Injector

On the 2.2L TDCi platform, a failing Delphi EJDR00601D injector typically presents as: hard cold starting or repeated cranking; rough idle or unstable running, especially when cold; misfire, hesitation and poor acceleration; white or black smoke at start-up or under load; diesel knock / rattle with reduced power.

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.

The documented failure modes on this platform are: injector back-leak beyond specification on high-mileage engines; injector seal leakage — visible diesel around an injector, in advanced cases raising the engine-oil level; nozzle wear causing over-fuelling and smoke.

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

Run a leak-off comparison across all four injectors — Delphi's documented Mondeo CRI diagnosis starts there. Check for visible diesel around the injectors and monitor the oil level on suspected seal leaks. Delphi injectors carry a C2I calibration code — program the new code after fitting. Separate fuel-metering / pump faults from injector faults before ordering parts.

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.

Each remanufactured EJDR00601D 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.

The EJDR00601D trusted family covers 1 verified vehicle fitment across 1 make: Ford. Every fitment listed on this page is registry-verified — no scraped or assumed applications.

EJDR00601D supersedes or cross-references 10 further OE numbers, including R00601D, HRD327, 5S7Q9K546AB, RM5S7Q9K546AB, 1334446, 1376299, 812014 and 812021. 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.
