How to troubleshoot engine issues on an Audi A1?

I have been experiencing issues with the engine on my Audi A1. It seems to be making strange noises and losing power. I am not sure what could be causing this and how to fix it. Can anyone provide some advice?

First, check your spark plugs as they are critical for the engine's performance. If they are worn out or dirty, they could be the culprit behind the strange noises and power loss. Also, make sure to inspect the air filter and replace it if needed.

Another common issue with Audi A1 engines is a faulty camshaft sensor. This can cause similar symptoms to what you are experiencing. It is recommended to have a mechanic perform a diagnostic to confirm if this is the issue and replace the sensor if necessary.
