What are the common maintenance issues of the Audi A2?

I am considering buying a used Audi A2 and want to know what to expect in terms of maintenance and potential issues.

One common issue with the Audi A2 is the failure of the camshaft tensioner. To avoid this issue, regular maintenance and oil changes are crucial to prevent excessive wear on internal engine components.

Another potential issue is with the transmission CVT belt. To ensure its longevity, it is important to replace the belt and transmission fluid at the recommended intervals.

The Audi A2 also has a known problem with the fuel filter. It is recommended to replace it every 20,000 miles to prevent fuel flow issues and potential engine damage.
