How do I troubleshoot a problem with the power steering in my Audi 80?

I've been experiencing difficulties with my power steering while driving my Audi 80. It feels like there is a lot of resistance and it's harder to turn the wheel. What could be causing this issue and how can I fix it?

It's possible that your power steering fluid is low or contaminated. Check the levels and replace the fluid if necessary.

Another common cause of power steering problems is a faulty steering pump. Consider getting it checked or replaced by a mechanic.

It could also be an issue with the steering belt. Check for any signs of damage or wear and replace as needed.
