What are common issues with the Audi A2 engine?

I recently bought an Audi A2 and I'm noticing some problems with the engine. What are some common issues I should be aware of?

A common issue with the Audi A2 engine is the failure of the camshaft position sensor. This can cause the engine to run rough or not start at all. It's important to have it checked and replaced if necessary to avoid further damage.

Another issue is the failure of the timing belt tensioner. This can lead to timing belt failure which can cause significant engine damage. It's recommended to have the timing belt and tensioner replaced every 60,000 miles as a preventative measure.
