What are the common issues with the Audi A2's power steering?

I've noticed my Audi A2's power steering has been acting up, with the steering feeling heavy at times. What could be causing this issue and how can I fix it?

The most common cause for heavy steering in the Audi A2 is low power steering fluid. Check the fluid levels and top up if necessary, and monitor for further changes in steering performance.

Another potential cause could be a faulty power steering pump or belt. Get these components checked and replaced if necessary to resolve the issue.
