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

The primary purpose of the engine glow plug light, which is generally represented by a yellow coil, is to ensure that your glow plugs are working effectively. Indeed, it must light up when you switch on your Peugeot Boxer 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 motor vehicle. Nevertheless, if it turns on while driving, it may suggest several issues, we will try to point out the most important ones.
