How to fix Audi cylinder misfire?
Spark Plugs: Check for wear, fouling, or damage. Worn-out spark plugs can cause weak or no ignition, leading to a misfire. Ignition Coils: A malfunctioning ignition coil can cause the spark plug to fail. If your Audi has coil-on-plug ignition, inspect the individual coils. Some of the most common causes for an Audi not starting include a dead battery, loose or corroded battery connections, alternator problems, fuel system issues, engine failure, ignition switch problems, and a dead key fob battery.
