What are common issues to look out for with the Audi A6's power steering system?

I recently purchased a used Audi A6 and have been noticing some strange behavior with the power steering. I want to make sure I am aware of any common issues that may arise with this system so I can keep an eye on them. Can you provide any insight and advice on what to look out for?

First and foremost, check the power steering fluid levels regularly. Low fluid levels or dirty fluid can cause issues with the system. Secondly, be on the lookout for any unusual noises or difficulty turning the steering wheel, as these can be signs of a potential problem. Additionally, make sure to have your steering system inspected regularly by a trusted mechanic to catch any issues early on.
