The average cost of a Audi A4 ignition coil is between $20.29 and $310.00.
The ignition coils in the Audi A4 are part of the ignition system and are responsible for amplifying the relatively low battery voltage of 12V to tens of thousands of volts for the spark plugs. Driving your A4 with faulty ignition coils can cause engine or catalytic converter damage, so you must act quickly to avoid more costly repairs.
The most common symptoms of a bad ignition coil in an Audi A4 are engine hesitation or loss of power when accelerating, rough idle, misfires, excessive fuel consumption, the check engine light illuminates, and sometimes hard starting. In the worst-case scenario, if the ignition coils are severely damaged, the engine will not start.
A damaged ignition coil cannot be repaired; it must be replaced. However, if the ignition coil has been contaminated by an oil leak in the spark plug tube/well and the end of the ignition coil boot has not become mushy, you may be able to restore its functionality by cleaning it with an electronic cleaner or MAF sensor cleaner in some cases. Nonetheless, if you notice corrosion or rust on any of your A4's ignition coils, they must be replaced.
