What is the common cause of engine vibration in Audi A6?

I've noticed that my Audi A6 tends to vibrate while idling or driving at low speeds. What could be causing this issue?

Engine misfiring is a common cause of vibration in Audi A6 cars. This can be due to faulty spark plugs or ignition coils. It's important to get this checked and replaced if necessary.

Another possible cause of engine vibration in Audi A6 is a worn out engine mount. This can cause the engine to shake and vibrate, especially during idle. It's recommended to get your engine mount inspected and replaced if needed.
