Why is my BMW Z4 making strange noises when I turn the steering wheel?

I recently started hearing strange noises when I turn the steering wheel of my BMW Z4. It almost sounds like a grinding or rubbing noise. What could be causing this and how can I fix it?

It's possible that your power steering pump or belt may need to be replaced. This issue is more common in older BMW Z4 models and can cause the strange noises you're experiencing.

Another potential cause could be worn out or damaged steering components, such as the tie rods or ball joints. These should be inspected and replaced if necessary.
