How to troubleshoot a faulty engine in an Audi A2?

I have been noticing some strange noises coming from my Audi A2's engine. How can I identify the issue and fix it? I am not very familiar with cars so any advice would be appreciated.

Hi Sarah, it sounds like your engine might need some maintenance. First, you should check the oil level and see if it needs to be topped up. If that doesn't solve the issue, take your car to a mechanic for a full inspection.

Hey Sarah, based on the noises you described, it could be an issue with the spark plugs or the fuel system. It's important to address these issues sooner rather than later to avoid any further damage to your car.

Hi Sarah, have you recently changed your air filter? A clogged air filter could also cause strange noises in the engine. It's an easy fix and you can do it yourself with the help of online tutorials.
