How can I prevent my BMW Z4's power steering from failing?

I have a BMW Z4 and recently, my power steering has been feeling more and more stiff. What could be causing this and how can I prevent it from failing completely?

One possible cause of your stiff power steering could be low power steering fluid. Check the fluid levels and add more if necessary. It is also important to check for any leaks that may be causing the fluid levels to deplete. Regularly checking and topping off the power steering fluid can help prevent steering failure.

Another potential issue could be a faulty power steering pump. If the pump is not working properly, the power steering will be affected. It is best to have a mechanic inspect and replace the pump if needed. Additionally, make sure to follow the recommended maintenance schedule for your BMW Z4 to ensure all components are functioning properly.
