What is the goal of my Renault Kadjar glow plug light?

The primary purpose of the engine glow plug light, which is most of the time 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 Renault Kadjar 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 automobile. However, if it turns on while driving, it may indicate multiple failures, we will try to detail the most important ones.

What to do if the glow plug light comes on while driving on my Renault Kadjar?

My Renault Kadjar glow light comes on and I’m going through a loss of power

The first possibility is that you perceive that your glow plug light comes on while driving your Renault Kadjar and that you also experience a loss of power. In such a case, some concerns can explain its lightning. Here is a list of the most important motives:

  • Problem of EGR valve, indeed, if you suffer a loss of power, it is possible that your EGR valve is blocked, in such a case, it is rational that your preheat light comes on while driving on Renault Kadjar because it is one of the problem of which it is meant to warn you. Have the status of your valve tested
  • Problem related to the turbo overflow valve, in this situation the ECU can no longer manage the turbo intake pressure, which can result in turbo boost and a disturbance in the operation of the turbo.
  • Problem in connection with the injection, either an injector that has seized up or the injection pump that is destroyed by filings or other possible foreign bodies that disrupt its proper performance.
  • Finally, the last trouble that could lead to a glow indicator light on your Renault Kadjar 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 Renault Kadjar

To conclude, we’ll give you the motives for a glow plug light that comes on on your Renault Kadjar without you feeling any difference in power or automobile behaviour. Generally, this is an electronic problem:

  • 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 get rid of the trouble.
  • You have a false contact somewhere in your electrical circuit, test the other alternatives first because it is not easy to find it alone, we suggest you to go to your mechanic.
  • Faulty injection pressure sensor, ECU error
