How to fix a faulty power steering system in an Audi 80?

My Audi 80's power steering system seems to be malfunctioning and it's becoming difficult to steer the car. What could be causing this issue and how can I troubleshoot and fix it?

The most common cause of a faulty power steering system in an Audi 80 is low power steering fluid. Check the fluid level and top it off if necessary. Also inspect for any leaks in the system.

Another possible cause could be a worn out power steering belt. Check if the belt is cracked or loose and replace it if needed.

If the power steering pump is making abnormal noises, it may need to be replaced. Also, check the power steering lines for any clogs or leaks that could be hindering the system.
