Why does my Audi A5's engine vibrate at high speeds?

I've noticed that my Audi A5's engine starts to vibrate when I reach speeds above 100mph. It's not a violent shake, but it is noticeable and concerning. What could be causing this and how can I fix it?

This could be caused by a variety of factors, such as worn out engine mounts, imbalanced tires, or a misfiring engine. I would recommend taking your car to a trusted mechanic to diagnose the issue.

I had a similar issue with my Audi A5 and it turned out to be a faulty spark plug. After getting it replaced, the engine vibration disappeared. Maybe have your spark plugs checked as well.
