Burnt-diesel smell with black tar-like build-up around an injector (the documented 'black death'); chuffing or hissing from the injector area at idle; hard starting, particularly warm starts; rough idle or misfire-like running; smoke and reduced power when a leak is advanced. When two or more appear together, suspect the injector before peripherals — a comparative leak-off test isolates the failed unit without tear-down.
Injector copper seal / seat failure letting combustion gas carbonise around the injector base; piezo injector internal faults degrading atomisation and drifting correction values out of range; injectors carboning into the bore when seal leaks are left unrepaired, making removal difficult. Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.
Inspect around every injector for black crust before diagnosis — the failure is often the seal and seat, not the injector body. Clean or recut the injector seat before fitting a replacement; always use a new copper sealing washer. Check injector correction values across all six cylinders — an outlier identifies the failing unit. Address seal leaks early: a long-running leak can seize the injector into the head. Never condemn a common-rail injector on a fault code alone.
Each remanufactured 0445116027 is fully stripped, ultrasonically cleaned and inspected; worn components are replaced with OE-grade parts. The rebuilt unit is calibrated on a common-rail test bench against the manufacturer's specification — delivery, back-leak and response verified — and despatched with a 12-month parts warranty and its calibration data on file.
The 0445116027 trusted family covers 5 verified vehicle fitments across 1 makes: Mercedes-Benz. Every fitment listed is registry-verified.
