Engine Glow Plug Light Blinking

Hello everyone, I welcome you all to my blog, in this vlog we will discuss the most important and common problem of every car which is Glow Plug light Blinking.


Mostly this problem occurs in Volkswagen cars earlier but now this is normal in every TDI engines.

There may be multiple reasons why this warning light gets blinking at any time.

I have a Skoda Rapid TDI 1.6, and I faced this issue multiple times in the past, to get things working properly, first of all, you need to know about some common sensors and major parts of the engine.

Some important Parts of your Car's Engine are:

1. Turbo.

2. Air Filter.

3. Intercooler.

4. Intake Manifold.

5. ECU.

6. EGR Valve.

7. Water Pumps.

Some Important Sensors of your Car's Engine you need to know about:

1. Turbo boost Pressure Sensor.

2. Turbo Boost Control Valve.

3. MAF sensor (Mass Air Flow Sensor).

4. Turbo actuator Valve.

If you are having enough knowledge of above-mentioned parts and sensors you will make things working very well in your car.

If you are driving a Skoda and Volkswagen car and if any of this above-mentioned part or sensor will stop working properly the ECU will detect it and starts flashing the Glow Plug light. 

In some worst cases, your car will drop overall pickup. 
Turbo will not give you the proper boost as it uses to give earlier.

This is known as Safe Mode.

Once the ECU identifies that there is some problem in any of the above-mentioned part or sensor it will put the engine into the safe mode after which engine will not give a performance to its upper limits.
You can try harder but you will not be able to raise the RPM to the maximum.

So, first of all, I will suggest you guys please perform an overall OBD scanning of your car only after that you will be able to diagnose that where the problem is.

Once the scanning is done the scanner will give you the error or fault code it may be anywhere inside the engine components or maybe in the sensors.

Common cars which face this engine glow plug related issue are:

  1. Volkswagen Vento TDI.
  2. Volkswagen Polo.
  3. Volkswagen Jetta.
  4. Skoda Rapid.
  5. Skoda Laura.
  6. Skoda Fabia.
  7. Skoda Superb.
  8. Audi.
  9. BMW.
  10. Mercedes.

Common Error codes or Fault codes in these cars which causes Glow Plug light starts flashing:
Normally Skoda and Volkswagen cars show these errors related to Boost pressure sensor:


  1. P0045 OBD-II Trouble Code Turbo/Super Charger Boost Control Solenoid Circuit/Open.
  2. P2262 OBD-II Trouble Code Turbo Boost Pressure Not Detected-Mechanical.
  3. Error Code P0234 Turbocharger Overboost Condition.
  4. PO299 code PO299 code is rather common diagnostic trouble code that indicates an under boost condition.
