0445020137 is supplied as a remanufactured replacement fuel injection part. Cross-reference numbers: 0445020137, 5258264. Application recorded for this part: ISDE ISBE ISB4.5. This is the last precision component in the fuel path. Everything upstream exists to deliver clean fuel at stable pressure; this unit decides when combustion starts and how completely the charge burns. That is why injector condition shows up so directly in noise, smoke and emissions. What owners usually notice first: longer cranking, a rougher idle, more smoke than the engine used to produce, worse consumption, and occasionally a metallic knock that appears under load and clears once the engine is revved. 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. Fitting notes: replace as a set rather than singly. A lone new injector will deliver differently from the worn ones around it, which usually reproduces the rough running. Use new sealing washers every time, clean the injector bore and seat carefully, and check whether your engine management expects classification codes to be entered after installation. Our rebuild standard: strip to components, clean, measure against wear limits, replace what is worn, machine back to specification where required, then calibrate and bench-test every unit. Delivery, return flow, opening pressure and leakage are recorded, and units outside specification are not dispatched. Test sheets available on request, and every unit carries a 12-month warranty.
