Glow Plugs - Overview - Eurostar Diesels

Have you seen the curly yellow Glow Plug light on your dashboard? It should show before startup, but never after the engine is running.

A Glow Plug is a heating element that heats the fuel and air within a diesel engine, ensuring quick starting in cold conditions. They are pencil shaped and are installed into the cylinder head of the engine. There is one for each cylinder. There is a control unit which controls when and for how long the glow plugs are heated by electrical current.

If your Glow light is illuminating after the engine starts, your engine ECU has detected a fault with the glow plugs or control unit. At this stage we recommend that you contact us promptly. We have a variety of diagnostic techniques to locate any faulty glow plugs specifically (for example cylinder No.1 + No.3) or control unit.
