Why does my Audi A2 constantly have problems with its steering system?

I recently purchased a used Audi A2 and have been having constant issues with the steering system. The car pulls to one side and the wheel feels loose and unresponsive at times. What could be causing this problem and how can I fix it?

The most likely cause for this issue is a malfunctioning power steering pump. It is common for these pumps to fail on older Audi models, such as the A2. It is recommended to have a mechanic inspect and replace the pump if necessary. If left unfixed, the steering system could become even more unstable and potentially dangerous.
