How do I know if my Audi A2 needs a new camshaft position sensor?

I have noticed some strange behavior in my Audi A2 and I suspect it may be due to a faulty camshaft position sensor. How can I determine if this is the issue and what steps should I take to replace it?

The easiest way to determine if your Audi A2 needs a new camshaft position sensor is to use a diagnostic tool to read the stored trouble codes. If the codes indicate an issue with the sensor, it's likely time for a replacement. When replacing the sensor, make sure to disconnect the battery and carefully follow the manufacturer's instructions.
