How can I fix the power steering in my 1992 Audi 80?

I have a 1992 Audi 80 and the power steering has recently stopped working. What could be causing this issue and what steps should I take to fix it?

The most likely cause of your power steering failure is a leak in the power steering fluid system. Check the fluid levels and look for any visible leaks. If the fluid levels are low, top up with the correct type of power steering fluid and check for leaks again.

Another possible cause is a faulty power steering pump. To check this, first make sure the belt driving the pump is tight and in good condition. If the belt is fine, try turning the steering wheel while the engine is running. If there is no resistance and the wheel turns freely, the pump may need to be replaced.

In some cases, the issue may be with the power steering rack and pinion. This may be caused by a worn or damaged seal, which can lead to loss of power assist. To fix this, the rack and pinion will need to be replaced.
