Volkswagens are your everyday cars; they are very reliable and easy to maintain. Nevertheless, if you own a Volkswagen Jetta, then you may want to pay extra attention to your ignition coil. An ignition coil failure remains one of the most frequently reported automobile repair problems among Volkswagen Jetta owners across 17 model years, from 1996 to 2014. The ignition coil is the engine component responsible for transferring high-voltage current from the car battery to the spark plugs. This power transfer is what lights up the car’s fuel and allows the engine to run. Essentially, this means that if the ignition coil fails, there would be no spark to ignite the air-fuel mixture. This would result in a misfire and consequentially, the engine will lose power which could be dangerous for the driver.
Like in the case of this 2010 Volkswagen Jetta, a faulty ignition coil could result in startup issues, stalling, hesitation, poor fuel economy and even engine fires to name a few! As you can see, it is best to get the ignition coil fixed immediately before it causes more damage to your car’s engine. Sometimes, if the engine does run, you could experience rough rides and poor gas mileage, necessitating frequent stops at the gas station. An illuminated check engine light could also point to an ignition coil failure. In cases of severe damage, you may notice a flashing check engine light, it is highly recommended you get your car to a mechanic immediately at this point.
Our mechanics at European Service Center will replace the ignition coil along as well put in all new spark plugs. Malfunctioning spark plugs could cause the ignition coils to operate at a higher output than they are designed to thus, causing the coils to wear our faster. Servicing and maintenance of the ignition coils and spark plugs should go hand in hand.
It is recommended that once your car has reached 40K miles, it may be necessary to replace your ignition coils. Remember, faulty ignition coils pose a major safety hazard and it can be avoided.
