They are essential for ignition in diesel-powered engines (as opposed to spark plugs in petrol engines); they heat the air/fuel mixture in the engine so it ignites easily under compression; they are built to be long-lasting and work reliably no matter what happens. However, occasionally external factors or faults with other components can lead to issues with glow plugs. Owing to their rarity, these can easily be missed or wrongly identified.
