What is the purpose of my Peugeot Traveller glow plug light?

The main intent of the engine glow plug light, which is in most cases represented by a yellow coil, is to assure that your glow plugs are working effectively. In reality, it must light up when you switch on your Peugeot Traveller to tell you that they are heating the intake air in your cylinders and must go out after a few moments when the engine is running. This preheat light is therefore not meant to stay or come on while driving with your vehicle. However, if it comes on while driving, it may reveal multiple failures, we will try to point out the main ones.
