  1. Find the Symptoms of Glow Plug Timer Relay Problems In Your Mercedes by Rowlett Mechanics

  2. Diesel engine of the Mercedes needs excess heat in cold weather for powering up the ignition process.

  3. So, it is using glow plugs instead of spark plugs for generating the required power in the engine.

  4. Glow plugs have a timer with relays for activating or deactivating the glow plugs at the appropriate times and intervals.

  5. Thus, the glow plug timer relay can provide the heat required for starting the car.

  6. The following points define the symptoms of failed glow plug timer relay in your Mercedes.

  7. Difficult Starting

  8. Thus, the glow plug timer relay can provide the heat required for starting the car.

  9. Simultaneously, it will affect the functions of the combustion chamber, ignition, and starting process in cold temperatures.

  10. Engine Misfiring

  11. For the smooth combustion process, your car needs accurate timing, a high compression ratio, and a quantity of fuel injection.

  12. When the glow plug timer relay is failed, it can cause the engine to misfire due to low fuel quality and engine compression.

  13. Reduced Fuel Mileage

  14. During winter months, the diesel of the engine is mixed with additives for lowering the freezing points of the fuel lines.

  15. When the glow plug timer relay is damaged, the fuel is blended and reduces the fuel mileage.

  16. Activated Glow Plug Warning Light

  17. When the ECU finds a problem within the engine operative system, it will affect the functions of the glow plug timer relay.

  18. If the computer detects any problem within the plug timer relay, the glow plug warning light is illuminated on the dashboard.

  19. Black Smoke

  20. Due to the imbalanced air/fuel mixture, the excess fuel in the engine is producing black smoke under the hood.

  21. In these consequences, the failed glow plug timer relay in your car is affected and emits black smoke through the exhaust pipe.

  22. Conclusion

  23. To prevent serious breakdowns of the glow plug timer relay of the Mercedes, you have to service it at a recommended interval.

  24. Driving the car with a failed glow plug timer relay can affect the engine performance and cause starting problems.
