Why is the steering on my BMW Z4 stiff?

I've noticed that the steering on my BMW Z4 has become increasingly stiff. What could be the cause of this and how can I fix it?

One possible reason for your stiff steering could be low power steering fluid or a faulty power steering pump. I suggest checking your power steering fluid levels and topping them up if needed. If that doesn't solve the issue, it would be best to take your car to a mechanic for further diagnosis.

Another potential cause could be worn out or damaged steering components, such as the steering rack or tie rods. This can happen over time and with normal wear and tear. You may need to replace these parts to restore smooth steering. It's best to consult with a mechanic for a proper inspection and repair.

It's also possible that the issue could be with the steering column or steering column shaft, which could have become loose or damaged. In this case, I recommend taking your car to a trusted mechanic to have them check and potentially replace these components as needed.
