Why does my Audi A3's engine shake when idle?

I have a 2015 Audi A3 with 50,000 miles and recently noticed that the engine shakes when I'm at a stoplight. What could be causing this and how can I fix it?

It could be due to a misfiring spark plug. I recommend getting it checked and replaced if necessary.

Your car's engine mounts may be worn out. This can cause vibrations in the engine. Have a mechanic inspect them and replace if needed.

One common cause of engine shaking is a faulty fuel injector. Have a technician run a diagnostic test to determine if this is the issue.
