Audi A3 Sedan Ignition coil replacement
Why do Audi A3 Sedan ignition coils need to be replaced?
An ignition coil channels electricity to your spark plugs, igniting the fuel in your Audi A3 Sedan engine’s cylinders.
A car battery is only 12 volts but thousands of volts are required to start a petrol combustion engine. That's why the coil is so important, it turns 12 volts into the thousands of volts needed to create the spark which initiates the ignition of the air-fuel mixture for combustion.
Diesel engines rely on compression to ignite the fuel so ignition coils are generally only installed in petrol engines. so if your Audi A3 Sedan is a diesel it's one less part to worry about.
A coil can fire hundreds of times per minute when your petrol Audi A3 Sedan is running – that wear and tear could mean ignition coil replacement is necessary during the life of your car.
