Why is my Audi A5 engine shaking when idle?

I recently noticed that my Audi A5's engine started shaking when I am at a complete stop. The car is relatively new and I want to understand what could be causing this issue.

One possible reason for your Audi A5's engine shaking at idle could be misfiring spark plugs, which can cause uneven power distribution and vibrations. It's important to have them checked and replaced if necessary. When was the last time you had a tune-up?

Another potential cause could be faulty motor mounts, which can cause excessive vibrations throughout the engine. This issue is more common in older cars, but it's still worth checking. Have you noticed any unusual noises or movements while driving?
