What is the goal of my Chevrolet Captiva glow plug light?

The main role of the engine glow plug light, which is generally symbolized 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 Chevrolet Captiva 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 automobile. However, if it comes on while driving, it may suggest different issues, we will try to point out the main ones.

  • Trouble related to the turbo overflow valve, in this situation the ECU can no longer manage the turbo intake pressure, which can cause turbo boost and a disturbance in the performance of the turbo.
  • Trouble related to the injection, either an injector that has seized up or the injection pump that is broken by filings or other possible foreign bodies that affect its proper performance.
