Why is the steering wheel of my Audi A3 vibrating?

I've noticed that the steering wheel of my Audi A3 starts vibrating when I reach high speeds on the highway. Is there something wrong with my car?

There could be a few reasons for this issue. First, check your tire pressure as low or unevenly inflated tires can cause vibrations at high speeds. Another possible cause could be an unbalanced wheel or worn out suspension components. If the problem persists, it's best to take your car to a mechanic for a thorough inspection.
