Common Injector Problems in Seat Leon

  • โ€ข
    Rough idle and engine vibration โ€” Worn injector nozzles cause uneven fuel spray, leading to rough idle at low RPM. Most noticeable when the engine is cold.
  • โ€ข
    Excessive exhaust smoke โ€” Black or blue-grey smoke on acceleration indicates poor fuel atomisation. This is often caused by carbon buildup on the injector nozzle tip.
  • โ€ข
    Poor fuel economy โ€” A worn or leaking injector delivers incorrect fuel quantities, reducing efficiency by 10โ€“20% in severe cases.
  • โ€ข
    Engine misfire under load โ€” Intermittent misfires during acceleration suggest one or more injectors are failing to deliver the correct fuel pressure.
  • โ€ข
    Difficult cold starting โ€” Degraded injector nozzles struggle to atomise fuel at lower cranking pressures, causing extended crank times in cold weather.
