What is the role of my Jaguar F-Type glow plug light?

The main goal of the engine glow plug light, which is in most cases represented by a yellow coil, is to ensure that your glow plugs are working effectively. In fact, it must light up when you switch on your Jaguar F-Type 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. This preheat light is therefore not supposed to stay or come on while driving with your motor vehicle. However, if it comes on while driving, it may reveal multiple issues, we will try to summarize the most important ones.
