🔌 Function

Meters and atomises diesel into the combustion chamber at the timing and quantity the control system commands, so the charge burns cleanly.

⚠️ Common Signs of Failure

• Rough or lumpy idle, or a distinct misfire on one cylinder
• Black or white smoke and a knocking, hard combustion note
• Hard starting, especially from cold
• Diesel smell and wet staining around the injector seat or the leak-off line
• Nozzle tip coked, eroded or dripping instead of spraying, found once it is out

🛠️ Service Notes

• Renew the copper seat washer and the sealing O-rings whenever an injector is drawn - they are single-use
• Check the leak-off return and the fuel filtration before condemning an injector, as dirty fuel takes out the replacement as quickly as the original
• Injectors are calibration-coded on this family, so any code carried by the injector must be entered into the control system after fitting
