How do I maintain the power steering in my BMW 8 Series?

I recently purchased a used BMW 8 Series and noticed that the power steering feels stiff and unresponsive. How can I properly maintain and improve the power steering system in my car?

First, make sure to check the power steering fluid levels and top up if necessary. You may also want to consider flushing the power steering system to remove any contaminants and improve performance. Additionally, check for any leaks or damage in the power steering system.

Perform regular maintenance on your BMW, such as regular oil changes, to ensure the power steering system is functioning properly. Also, avoid overloading your car and driving on rough roads, as this can put extra strain on the power steering system.

Consider upgrading to a higher quality power steering fluid, such as a synthetic fluid, to improve the responsiveness of your power steering. It's also important to regularly check the condition of your power steering belt and replace it if needed.
