What causes my Audi A6 to shake while idling?

I have noticed that my Audi A6 shakes noticeably while in idle. What could be the cause of this and how can I fix it?

It is possible that your spark plugs are worn and need to be replaced. This can cause shaking and rough idling. I recommend taking your car to a trusted mechanic to have them checked.

Another potential cause could be a vacuum leak which can also cause shaking at idle. I suggest bringing your car to a mechanic to have them check for any leaks and make any necessary repairs.

It is also possible that your engine mounts are worn out, leading to shaking at idle. I would recommend getting your car checked by a mechanic to confirm and replace any worn mounts.
