How to Deal with an Ignition Coil Failure in a Volkswagen
Post on December 13, 2021 by ultimateauadmin
The ignition coil in your Volkswagen is a tiny transformer that converts low-voltage electricity from the battery to the high-voltage electricity required to ignite the fuel with an electric spark in the spark plugs. Among its components are the iron core, electrical connections, as well as primary and secondary windings.
An ignition coil failure is when the ignition coil fails to carry out its duty, as stated above, resulting in performance issues. If you are having problems with the ignition coil in your Volkswagen, this article contains what you need to know about ignition coil failure and how to properly recognize it.
Symptoms of a Faulty Ignition Coil
A car is similar to the human body. Just as the body gives signs indicating illness when a person is about to fall ill, a car does the same when a part becomes faulty before its subsequent breakdown. Before anything spoils in a vehicle, there are some telltale signs. Let’s see what some symptoms indicating a defective ignition coil system:
- Poor Fuel Economy: If you notice a significant reduction in the mileage you get from your gas, you might want to consider getting the ignition coil checked. While this might be attributed to other factors, you can’t rule out the possibility of a faulty ignition coil.
- Backfiring: When the unused gasoline in the engine’s combustion cylinders escapes through the exhaust pipe, the car backfires. This is one symptom you get during the early stages of ignition coil failure.
- Vehicle Stalling: This can happen due to the malfunctioning coil sending out erratic sparks to the spark plugs. When you bring your car to a stop, it may turn off completely, leaving you with the trouble of getting it started again.
- Engine Misfiring: When the ignition coils of a vehicle fail, the engine will misfire. Starting such a vehicle will result in sounds like coughing and sputtering. When traveling at high speeds, the vehicle’s behavior will include jerking and spitting. Also, when the car is idling, it vibrates.
Causes of Ignition Coil Failure
There are four main causes of ignition coil failure in Volkswagen:
- Internal Short Circuits: When the ignition coil overheats, it frequently short circuits. This can occur due to aging, module faults, or problems with the electronic control unit’s output stage.
- Mechanical Damage: The likelihood of spark over and accelerated wear increases dramatically when the valve cover gasket or the ignition cables fail.
- Problems With the Voltage Supply: If the ignition coils receive insufficient voltage, they will be less effective and take longer to charge. This is often caused by attrition or an overloaded ignition coil. A faulty battery or connections can also cause this issue.
- Contact Faults: Humidity in your engine, caused by liquid left behind from engine washing, might result in contact failures.
