What are the common issues with the engine of the Audi A2?

I recently purchased an Audi A2 and I've noticed some issues with its engine. It's making strange noises and it seems like it's not running as smoothly as it should. Can anyone provide some insight into common problems with the Audi A2's engine? Any advice on how to fix or prevent these issues would be greatly appreciated.

One common issue with the Audi A2's engine is a malfunctioning camshaft position sensor. This can cause strange noises and affect the engine's performance. It's important to get this fixed as soon as possible to prevent further damage to the engine.

Another possible cause for the engine's noise and reduced performance could be a dirty or clogged fuel injector. Make sure to regularly clean or replace the fuel injectors to avoid potential engine problems.

If you've noticed a decrease in fuel efficiency and a lack of power in your Audi A2, it could be due to a faulty oxygen sensor. This can often be an easy fix and will improve the overall performance of your engine.
