Why does my Audi A7 make a strange noise while turning?

I recently noticed that my Audi A7 makes a strange noise whenever I turn the steering wheel. It's not a constant noise, but rather a brief sound that only lasts for a second. What could be causing this and is it something I should be concerned about?

It is most likely caused by the power steering system. You may be low on power steering fluid or there could be an issue with the power steering pump. I suggest bringing your car to a mechanic to have it checked out.
