What is the purpose of my Dacia Sandero glow plug light?

The main role of the engine glow plug light, which is generally represented by a yellow coil, is to make sure that your glow plugs are working properly. In fact, it must light up when you switch on your Dacia Sandero to tell you that they are heating the intake air in your cylinders and must go out after a few minutes when the engine is running.
