What is the goal of my Vauxkhall Moka glow plug light?

The main intent of the engine glow plug light, which is most of the time symbolized by a yellow coil, is to guarantee that your glow plugs are working effectively. In fact, it must light up when you switch on your Vauxkhall Moka 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 car. But, if it turns on while driving, it may suggest multiple troubles, we will try to explain the most important ones.

What to do if the glow plug light comes on while driving on my Vauxkhall Moka?

A glow light that comes on while driving on your Vauxkhall Moka or at any other time other than when the engine is started is meant to warn you to a fault other than your spark plugs, we will take a look at this now. Whatever the case, connecting your vehicle to the diagnostic tool will allow you to carefully interpret the cause for the light up of your glow light.

My Vauxkhall Moka glow light comes on and I’m suffering from a loss of power

The first possibility is that you notice that your glow plug light comes on while driving your Vauxkhall Moka and that you also encounter a loss of power. In such a case, several concerns can describe its lightning. Here is a list of the most important reasons:

  • Problem of EGR valve, in fact, if you suffer 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 Vauxkhall Moka because it is one of the problem of which it is meant to alert you. Have the status of your valve checked out
  • Issue related to the turbo overflow valve, in this situation the ECU can no longer control the turbo intake pressure, which can lead to turbo boost and a perturbation in the operation of the turbo.
  • Issue in connection 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 disturb its proper functioning.
  • Finally, the last problem that could lead to a glow indicator light on your Vauxkhall Moka coupled with a loss of power, is that your fuel filter is too dirty, you should get 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 Vauxkhall Moka

Finally, we’ll give you the causes for a glow plug light that comes on on your Vauxkhall Moka without you feeling any difference in power or car behaviour. Ordinarily, this is an electronic fault:

  • Glow plug relays or fuses to be swapped out, test and change 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 out the other alternatives first because it is not easy to find it alone, we suggest you to go to your auto mechanic.
  • Faulty injection pressure sensor, ECU error
