How do I fix a broken power steering in my Audi 80?

My power steering suddenly stopped working and the steering wheel has become very hard to turn. What could be causing this issue and what steps should I take to fix it?

First, check the power steering fluid level to make sure it's not low. If it is, refill it and check for any leaks. If the fluid level is fine, it could be a problem with the power steering pump or belt. I recommend taking your car to a mechanic to diagnose and repair the issue.
