Common failure symptoms
On the 2.0/2.2L TDCi/CDI platform, a failing Delphi EJDR00701D injector typically presents as: cold-start rattle and white smoke; hard starting or non-start when warm; uneven idle and cylinder knock; loss of power under load; fuel knock worsening with mileage.
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: delphi injector internal wear causing rising back-leak; injector calibration drift causing rough running despite no hard fault; electrical connector faults logging injector circuit codes.
Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.
How Workshops Diagnose EJDR00701D Faults
Delphi injectors on this platform carry a C2I calibration code — programme it after fitting or expect rough running. Run a leak-off comparison across all four injectors; a single high return identifies the failing unit. Check the injector loom and connectors above the rocker cover for heat damage before condemning injectors.
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 EJDR00701D 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
EJDR00701D supersedes or cross-references 20 further OE numbers, including R00701D, HRD328, W00701D, DFIR00701D, GID30701D, 6S7Q9K546AA, RM6S7Q9K546AA and 1361895. 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.
