Why would the Audi A5 engine shake while idling?

Sometimes when I am stopped at a light or in park, my Audi A5's engine will start to shake violently. It feels almost like the car is going to turn off. What could be causing this shaking and how can I fix it?

The most common cause of engine shaking while idling is a misfiring cylinder. This can be caused by a variety of issues, such as a faulty spark plug, fuel injector, or ignition coil. We recommend bringing your car to a trusted mechanic for a thorough inspection and potential repairs.

Another possible reason for engine shaking at idle is a dirty or clogged air filter. A dirty air filter restricts airflow to the engine, causing it to run rough. You can easily check your air filter and replace it if necessary. If the issue persists, a mechanic can further diagnose the problem.
