How do I troubleshoot a malfunctioning power steering system in my Audi A8?

I noticed that my Audi A8's power steering system is not functioning properly. What could be causing this issue and how can I fix it?

First, check if the power steering fluid level is low. If so, top it off and see if that resolves the issue. If not, there may be a problem with the power steering pump or the steering rack. It's best to take it to a certified mechanic for a proper diagnosis and repair.

Another possible cause could be a faulty power steering belt. Check for any cracks or signs of wear and replace it if necessary. If the belt is fine, there may be an issue with the power steering control module. Again, it's best to consult a mechanic for further assistance.

Make sure to also check the power steering fluid reservoir for any leaks. If there is a leak, it will need to be repaired as soon as possible to avoid further damage to the system. You can use a UV dye kit to help locate the source of the leak.
