What is the goal of my Peugeot 207 glow plug light?

The main goal of the engine glow plug light, which is most of the time symbolized by a yellow coil, is to ensure that your glow plugs are working correctly. In reality, it must light up when you switch on your Peugeot 207 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 supposed to stay or come on while driving with your car. However, if it comes on while driving, it may suggest multiple troubles, we will try to point out the main ones.

The first probability is that you identify that your glow plug light comes on while driving your Peugeot 207 and that you also experience a loss of power. In this instance, several trouble can explain its presence. Here is a list of the main factors:

  • Trouble of EGR valve, indeed, if you undergo a loss of power, it is possible that your EGR valve is clogged, in this case, it is expected that your preheat light comes on while driving on Peugeot 207 because it is one of the failures of which it is supposed to alert you. Have the status of your valve checked
  • Issue linked to the turbo overflow valve, in this situation the ECU can no longer control the turbo intake pressure, which can bring about turbo boost and a perturbation in the operation of the turbo.
  • Issue linked to the injection, either an injector that has seized up or the injection pump that is malfunctioned by filings or other possible foreign bodies that disturb its proper operation.
