What is the purpose of my Genesis G80 glow plug light?

The main goal of the engine glow plug light, which is generally represented by a yellow coil, is to ensure that your glow plugs are working effectively. In reality, it must light up when you switch on your Genesis G80 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 vehicle. However, if it turns on while driving, it may reveal several troubles, we will try to point out the most important ones.

What to do if the glow plug light comes on while driving on my Genesis G80?

A glow light that comes on while driving on your Genesis G80 or at any other time other than when the engine is started is designed to warn you to a problem other than your spark plugs, we will take a look at this now. In any case, a switch to the diagnostic tool will allow you to accurately translate the cause for the light up of your glow light.

My Genesis G80 glow light comes on and I’m having a loss of power

The first possibility is that you detect that your glow plug light comes on while driving your Genesis G80 and that you also encounter a loss of power. In this case, some concerns can demonstrate its presence. Here is a list of the most important motives:

  • Trouble of EGR valve, indeed, if you are affected a loss of power, it is possible that your EGR valve is clogged, in this case, it is rational that your preheat light comes on while driving on Genesis G80 because it is one of the failures of which it is intended to notify you. Have the status of your valve checked out
  • Trouble related to the turbo overflow valve, in this situation the ECU can no longer manage the turbo intake pressure, which can bring about turbo boost and a disturbance in the operation of the turbo.
  • Trouble associated with the injection, either an injector that has seized up or the injection pump that is damaged by filings or other possible foreign bodies that disrupt its proper performing.
  • Finally, the last problem that could lead to a glow indicator light on your Genesis G80 coupled with a loss of power, is that your fuel filter is too dirty, you should experience jerks because of a bad fuel flow in the engine.

My glow plug light comes on or is flashing but no difference on the performance of my Genesis G80

Finally, we’ll give you the causes for a glow plug light that comes on on your Genesis G80 without you feeling any difference in power or vehicle behaviour. Generally, this is an electronic problem:

  • Glow plug relays or fuses to be replaced, test and replace if necessary.
  • A contactor/potentiometer on one of your pedals (brake, accelerator or clutch) has failed, often a simple de-seizure will be enough to fix the problem.
  • You have a false contact somewhere in your electrical circuit, test the other options first because it is not easy to find it alone, we suggest you to go to your auto technician.
  • Faulty injection pressure sensor, ECU error
