Among the various cars that one gets to see on the road, there are few brands that overwhelm others with respect to their road presence. One such automobile manufacturer is Volkswagen which is very popular among the masses due to its reliability.

The German-engineered Volkswagen has been ruling the roads of many countries for the last couple of decades. This is because the automobile manufacturer constantly strives to bring something new in the various models it manufactures.

The popularity of Volkswagen can be gauged from the number of these cars one gets to see on the road of Rowlett. However, like other cars, Volkswagen has also got its fair share of issues that needs to be identified quickly before the problems cause any more additional damages.

Most VW drivers fail to identify ignition coil issues in their cars. The ignition coil is part of the ignition system in your car & it is imperative for VW owners to know the symptoms exhibited by the car so that remedial measures can be taken immediately.

Here in this article, we will discuss the symptoms exhibited by VW when the ignition coil goes bad.

Functioning of the ignition coil

The ignition coils in your VW are like electrical transformers and they are responsible for converting the low 12-volt current generated by the battery into a much higher voltage that is needed to ignite the fuel and start the engine. Each spark plug in your car is equipped with its own ignition coil.

The ignition coil is either connected physically to the spark plug with wires or is located on top of the spark plug without using wires. The spark plugs require 15,000 to 20,000 volts of electricity in order to form an electric spark that can ignite the fuel.

However, if the ignition coil is malfunctioning, then it leads to weak fuel consumption and engine misfires. Issues in the ignition coil can also be related to low voltage or high voltage from the battery. However, most of the time it is the ignition coil that is found to be faulty.

Symptoms of a bad ignition coil

Let us have a look at the symptoms of a bad ignition coil in your Volkswagen.

Backfiring & poor performance

If you experience backfiring from your Volkswagen while driving, then you can be sure of ignition coil issues in your car. The backfiring in your car will also be accompanied by a drop in the performance of the VW. This implies that the ignition coil is in the early stages of failure.

The backfiring in your VW occurs when the unused fuel in the combustion chamber leaves the engine through the exhaust pipe. If the problem is not addressed in time, it can damage the engine & lead to costly repairs. The emergence of black smoke from the exhaust along with the smell of gasoline indicates ignition coil failure.

Poor fuel economy

When the ignition coil malfunctions, the engine loses its ability to burn the fuel completely. This results in the engine requiring more fuel to run than what was previously being consumed leading to the decrease in the fuel efficiency of your Volkswagen.

In addition to this, it can also create problems for the oxygen sensor which results in the flow of more fuel to the engine than what is required. This unspent fuel in the engine can also adversely affect the catalytic converter in your car.

Misfiring & stalling engine

When there are issues in the ignition coil of your car, it often leads to the misfiring of the pistons as the charge is not delivered to ignite the gasoline. Moreover, if you are experiencing abnormal sounds along with a poor response from the engine leading to jerks & vibrations when idling, then this signifies the failure of the ignition coil.

If the issue isn’t addressed immediately and the problem persists, then your engine might shut down completely leaving you stranded in the middle of the road. This can be really irritating when you are out on some important assignments.

Finally

The above-discussed factors are some of the most common symptoms that are associated with the malfunctioning ignition coil in your Volkswagen. Most of the time people tend to ignore the symptoms during their initial stages. However, if you come across these symptoms, then you should replace the ignition coil of your Volkswagen.
