Why is my Audi A5 shaking while driving?

I recently purchased a used Audi A5 and noticed that the car shakes while driving at high speeds. What could be causing this issue and how can I fix it?

The most common cause of shaking while driving is a problem with the tires. Check the pressure and make sure they are properly inflated. If that doesn't solve the issue, it could be an alignment problem.

Another possible cause could be an issue with the suspension system. Take your car to a mechanic to get it checked out and potentially get the suspension components replaced.

If your car is equipped with a manual transmission, the shaking may be caused by improper shifting. Make sure you are shifting smoothly and at the proper RPMs.
