Why does my Audi A3 shake at high speeds?

I recently bought a used Audi A3 and I noticed that it starts to shake significantly as I reach speeds above 70mph. What could be causing this and how can I fix it?

This shaking could be caused by a number of factors, including worn out tires, misaligned wheels, or suspension issues. I recommend taking your vehicle to a trusted mechanic for a thorough inspection. It's important to address this issue as it can affect your overall driving experience.

I experienced a similar issue with my Audi A3 and it turned out to be a loose engine mount. Make sure to have all your engine mounts checked as they play a crucial role in keeping your engine stable and reducing vibrations. This can also be a sign of a larger underlying issue.
