0445110505 is supplied as a remanufactured replacement injector. Cross-reference numbers: 0445110505, 1J801-53051, 1J80153051. Fuel is delivered to this injector already pressurised by the rail. What it contributes is timing and atomisation — opening and closing within milliseconds, several times per combustion event on modern engines. Small changes in spray pattern or opening behaviour show up quickly as noise, smoke and rising consumption. Typical signs are poor starting hot or cold depending on whether the unit is weeping or sticking, an idle that hunts or sounds uneven, smoke under acceleration, and sometimes a smell of diesel in the oil where an injector is leaking internally. It costs little to confirm the diagnosis first. Compare return flow between cylinders and cut each injector in turn on a scan tool; if one cylinder makes no difference to running quality, that is your culprit. Installation notes: new copper washers and seals are mandatory, the seat must be clean and undamaged, and the retainers should be torqued to the engine manufacturer's specification. If the ECU stores injector codes for this engine, program them after fitting, otherwise the engine will not compensate correctly. How we build it: the unit is fully disassembled, cleaned and measured, not simply resealed. Wear items — seals, springs, and where clearance is out of specification the plunger and barrel or nozzle assemblies — are replaced rather than reused. Sealing faces and bores are re-machined back to original clearances, then the unit is calibrated and run on a bench with delivery, return flow, opening pressure and leakage recorded. Anything outside specification does not ship. Test sheets for your specific units are available on request. Covered by a 12-month warranty.
