Glow plugs are an essential component of a diesel engine, as they play a vital role in starting the engine by heating the combustion chamber. Sprinter vans, which are popular among commercial and personal users alike, are known to experience issues with glow plug failure, which can lead to difficulty in starting the vehicle, reduced fuel efficiency, and even engine damage. In this article, we will discuss the causes and symptoms of glow plug failure in Sprinter vans and the steps you can take to address the problem.

Causes of Sprinter Glow Plug Failure

The most common cause of glow plug failure in Sprinter vans is wear and tear over time. Like any other component, glow plugs have a finite lifespan and will eventually wear out. Other factors that can contribute to glow plug failure include poor maintenance, exposure to extreme temperatures, and poor fuel quality.

Symptoms of Sprinter Glow Plug Failure

One of the most common symptoms of glow plug failure in Sprinter vans is difficulty in starting the engine, especially in cold weather. When a glow plug fails, it will not be able to heat the combustion chamber adequately, making it harder for the engine to start. This problem can be especially frustrating for those who rely on their Sprinter van for work, as it can lead to delays and lost productivity.

Another symptom of glow plug failure is reduced fuel efficiency. When a glow plug is not functioning correctly, the engine will not burn fuel as efficiently, leading to reduced mileage and increased fuel costs. If you notice that your Sprinter van is not getting the same mileage as it used to, it may be time to check the glow plugs.

Finally, glow plug failure can lead to more severe engine problems if left unchecked. A poorly functioning glow plug can cause damage to other engine components, leading to more expensive repairs down the road.

Addressing Sprinter Glow Plug Failure

If you are experiencing difficulty starting your Sprinter van or notice reduced fuel efficiency, it may be time to address the glow plug issue. The following are some steps you can take to address the problem:

  • Diagnose the Problem: The first step in addressing glow plug failure is to diagnose the problem. This can be done by using a diagnostic tool to read the engine’s error codes or by visually inspecting the glow plugs for damage or wear. If you are not comfortable diagnosing the problem yourself, it is best to take your Sprinter van to a professional mechanic.
  • Replace the Glow Plugs: Once you have diagnosed the problem, the next step is to replace the faulty glow plugs. Glow plugs are relatively inexpensive, and replacing them is a relatively simple process that can be done at home with basic tools. However, if you are not confident in your ability to replace the glow plugs yourself, it is best to take your Sprinter van to a professional mechanic.
  • Check the Glow Plug Module: In some cases, glow plug failure may be due to a faulty glow plug module. The glow plug module is responsible for controlling the power supply to the glow plugs, and if it fails, the glow plugs may not function correctly. If you have replaced the glow plugs and are still experiencing problems, it may be time to check the glow plug module.
  • Maintain Your Sprinter Van: Finally, the best way to address glow plug failure is to maintain your Sprinter van properly. This includes regularly changing the oil and oil filter, checking the air filter, and using high-quality fuel. By maintaining your Sprinter van, you can help prevent glow plug failure and other engine problems.
