Why does my Audi A6's power steering feel heavy?

I've noticed that my Audi A6's power steering has been feeling heavy lately. It's becoming increasingly difficult to turn the wheel. What could be causing this issue and how can I fix it?

It's likely that your power steering fluid is low. Check the level and top it off if necessary. If the issue persists, it could be a malfunction in the power steering pump.

Your power steering belt may be loose or worn out. Inspect the belt and replace if necessary. If the issue persists, it could be a problem with the power steering rack.

If your Audi A6 is equipped with electric power steering, the issue could be with the motor or sensors. Take it to a mechanic for further diagnosis and repair.
