Why is my BMW Z4 making a strange noise when I turn the wheel?

I've recently noticed that my BMW Z4 is making a strange noise whenever I turn the steering wheel. It sounds like a high-pitched squeaking sound. What could be causing this and should I be worried about it?

Hi Mark, it's important to get this checked out by a mechanic as soon as possible. It could be a sign of an issue with your power steering system or the steering column. Make sure to describe the noise and when it occurs to the mechanic for a proper diagnosis.
