Why is my Audi A6 making a strange noise when I turn the wheel?

I noticed that my Audi A6 has been making a strange noise whenever I turn the wheel. What could be causing this and how can I fix it?

The most likely cause of the strange noise is a problem with the power steering system. It could be due to low power steering fluid or a faulty power steering pump. I would recommend checking the fluid levels and having it inspected by a mechanic.

Another potential cause could be an issue with the wheel bearings. They may be worn out or in need of lubrication. It's best to have a professional take a look and replace them if necessary.
