What is the cause of steering wheel vibration in my Audi A5?

I recently noticed that my Audi A5's steering wheel vibrates when I drive at high speeds. What could be causing this and how do I fix it?

Steering wheel vibration can be caused by unbalanced tires. It is important to have your tires balanced regularly to prevent this issue.

Another possible cause is a worn or damaged tie rod end. It is important to have this part checked and replaced if necessary to avoid further damage.

A misaligned suspension can also cause steering wheel vibration. Make sure to have your suspension checked and aligned by a professional mechanic.
