How to Deal with a Volkswagen’s Ignition Coil Failure

A common problem that Volkswagen owners may face is ignition coil failure. This problem can cause your car or SUV to experience reduced power, misfire, and even fail to start altogether. If you are experiencing ignition coil failure, it is important to understand what this problem is, the causes, and how to deal with it.

An ignition coil is an essential component of your VW’s ignition system. It is responsible for transforming the 12 volts from your battery into the high voltage required to ignite the fuel and air mixture in your engine’s cylinders. The coil does this by using a magnetic field to create a spark, which then ignites the fuel. When the ignition coil fails, it can no longer generate the spark required to ignite the fuel, causing your vehicle to experience problems starting or running.

What causes ignition coil failure?

There are a number of factors that can cause ignition coil failure, including:

What Causes Volkswagen Ignition Coil Failure

  • Wear and Tear: Over time, the ignition coil can become worn out from normal use, which can cause it to fail.
  • Electrical Issues: If there is an electrical problem in your vehicle, it can cause the ignition coil to overload.
  • Overheating: If the ignition coil overheats, it can cause damage to the internal components which will result in breakdown of the coil and its parts.
  • Age: Over time, the internal components of the ignition coil can degrade and will need to be replaced. This is natural, as the coils cannot be built to last forever.
  • Vibration: If your vehicle experiences excessive vibration, it can cause damage to the ignition coil and cause problems for your VW’s engine.
  • Moisture: Moisture can enter the ignition coil and cause corrosion. This will cause a slow degradation of your ignition coil, resulting in problems starting.

Replacing the Ignition Coil

If your VW is experiencing ignition coil failure, the best solution is to replace the faulty coil. This will typically require removing the old coil and installing a new one. The process of replacing the ignition coil will vary depending on your make and model, but it typically involves removing the old coil, installing the new one, and connecting the electrical connections. It is important to consult with a professional mechanic to help you with this process to avoid causing more damage to your vehicle.

Checking for Other Issues

Before replacing the ignition coil, it is important to check for other issues that may be causing the failure. This may include checking the spark plugs, the electrical system, and the wiring. If there is a problem with the spark plugs, they will need to be replaced. If there is an electrical problem, it will need to be repaired before the ignition coil can be replaced. This can help ensure that the problem is resolved and prevent future issues from occurring.

Regular Maintenance

Regular maintenance, such as routine tuneups and inspections, can help prevent ignition coil failure by keeping your VW in good condition. This can include checking the spark plugs, checking the electrical system, and checking the wiring. Regular maintenance can also help you identify potential problems early on, so you can address them before they become more serious.

Investing in a Quality Ignition Coil

When replacing the ignition coil, it is important to invest in a quality one that is designed to last. This will help prevent future problems and ensure that your vehicle runs smoothly. You can find high-quality ignition coils from reputable manufacturers or dealers. Investing in a quality ignition coil can also help to ensure that the replacement will last longer, saving you money in the long run. It is important to follow the manufacturer’s instructions when installing the new ignition coil to ensure that it is installed correctly and functions properly.
