What are the most common issues with the Audi A5's power steering system?

I've noticed some strange noises and vibrations when turning my Audi A5. Is this a known issue with the power steering system?

The most common issue with the Audi A5's power steering system is a faulty power steering pump. This can cause noises, vibrations, and difficulty steering. My recommendation is to have the pump checked and replaced if necessary.

Another common issue is a leak in the power steering fluid reservoir. This can lead to loss of power steering and potential damage to other components. I suggest checking the reservoir and replacing it if there are any signs of leakage.
