Delphi 28388960 Diesel Injector

On the 2.0L HDi platform, a failing Delphi 28388960 injector typically presents as: hard or extended cranking when warm; rough idle with cylinder balance corrections; loss of power under load / limp mode; excess black smoke during acceleration; repeated dpf regeneration warnings; rail-pressure faults logged alongside injector 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.

The documented failure modes on this platform are: injector back-leak beyond specification, dropping rail pressure at start; nozzle carbon build-up causing over-fuelling and dpf loading; injector seat sealing failure allowing combustion gas blow-by.

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

Run a comparative leak-off test across all four injectors before condemning one. Inspect injector seats for carbon and clean before fitting — reusing a fouled seat causes repeat failures. Delphi injectors on this platform carry calibration data that must be registered following the manufacturer procedure after fitting. If rail-pressure codes accompany injector codes, verify the high-pressure pump and regulator before replacing 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.

Each remanufactured 28388960 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 28388960 trusted family covers 17 verified vehicle fitments across 3 makes: Peugeot, Citroen and Ford. Every fitment listed on this page is registry-verified — no scraped or assumed applications.

28388960 supersedes or cross-references 6 further OE numbers, including 28602948, HRD360, 28319895, 9674984080, DS7Q9F593BA and DS7Q9F593BB. 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.
