Why is my Audi making a knocking noise when turning?

I recently noticed a loud knocking noise coming from my Audi when I turn the steering wheel. It seems to be coming from the front of the car. What could be causing this and how can I fix it?

It is likely that your power steering fluid is low. Check the levels and refill if necessary. If the issue persists, it could be a problem with the power steering pump or belt.

Another possibility is worn-out ball joints or tie rod ends. These should be inspected and replaced if necessary to prevent further damage to your car.
