Volkswagen Ignition Coil Symptoms & How To Identify Them

Would you recognize Volkswagen ignition coil symptoms if they occurred in your vehicle? Please continue reading to learn how to understand the function of spark coils, recognize when they require service, and take steps to resolve the issue.

In addition to this guide, the skilled technicians at our in-house DARCARS Volkswagen of Silver Spring service center are also a great source of support and information; feel free to call us with any questions about your ignition coil or any other components of your vehicle.

What Does a Volkswagen Ignition Coil Do?

Exclusive to internal combustion models, Volkswagen ignition coils are integral to your vehicle's ignition apparatus. When you turn your car or SUV into the "on" position, your coil activates the battery at a low voltage, allowing you to use your radio, lights, and other electrical components. Firing up the ignition triggers the coil to convert the low battery voltage into a much higher voltage, which is necessary for the spark plugs to ignite the fuel in your internal combustion engine.

As you can see, the ignition coil is vital to the ignition process. You can think of it as a magic wand that generates enough energy to start your car. When it is not functioning properly, significant problems can occur. Responsible car owners should learn to identify Volkswagen ignition coil symptoms early to avoid costly repairs down the road. Whether you have the expertise to tackle a compromised coil yourself or want to know when to bring your vehicle into a certified service center, it helps to understand what to look out for.

Can You Drive Your Car With a Bad Ignition Coil?

There is another reason why it is so important to become aware of Volkswagen ignition coil symptoms: safety. A faulty coil means an unreliable ignition system, and it is not advisable to drive with engine troubles. If you flag any of the symptoms discussed below or any other concerning engine problems, please pull over immediately and reach out for professional help.

If you experience signs of ignition coil issues that seem minor enough to ignore, you must address them anyway. Waiting for the issue to worsen could damage your engine and lead to more expensive repairs in the future. In the meantime, your fuel efficiency can decline, forcing you to spend more time and money at the gas station. For safety, fuel efficiency, and to protect your wallet, act fast when you notice the following red flags.

What Are the Symptoms of a Bad Coil in a Volkswagen?

1. Your Volkswagen is burning through gas quickly: Are you traveling the same distances as usual but filling up on gas more frequently? This can mean your coil is not sending enough power to your spark plugs.

2. Your Volkswagen feels sluggish and less responsive: As a car owner, you are attuned to performance changes for your Volkswagen. If you notice a slower response when stepping on the gas pedal, this could indicate that you have a coil problem.

3. You experience vibrating or jerking sensations while driving: Another way to tell something has gone awry with your ignition coil is your vehicle vibrating while idling or jerking forward while accelerating.

4. You are struggling to start your ignition: When you fire up your ignition, a functioning coil makes a crisp clicking sound, and the car should run immediately. If it is slow to start, it might be because of your coil. However, if your Volkswagen key won't turn in the ignition at all, this could indicate a dead battery.

5. You hear strange noises from the engine: Pay close attention to how your engine sounds when you start the ignition. Coughing or spluttering noises are a bad sign.

6. Your engine stalls: Is your vehicle stalling mid-drive or while stopped? This is another indication that your ignition coil needs to be looked at.

7. Your Volkswagen backfires or misfires: Of all the Volkswagen ignition coil failure symptoms, this is one of the most concerning. Loud banging sounds or black smoke emissions mean it's time to pull over and call for help.

8. The check engine light is illuminated: Always be vigilant about your dashboard symbols and what they are trying to communicate. The check engine light, in particular, should never be ignored.
