How can I troubleshoot my Audi A1's engine misfire issue?

My Audi A1's engine seems to be misfiring, and I'm not sure what could be causing it. What steps can I take to diagnose and fix this issue?

First, I would recommend checking your spark plugs and ignition coils. These are common culprits for engine misfires. You can visually inspect them for any damage or wear, and also try swapping them with known good ones to see if the problem persists.

Another potential cause could be a clogged fuel injector. You may want to try using a fuel system cleaner to see if that improves the issue. If not, it may be worth getting a professional cleaning or replacement.

Additionally, make sure to check your air filter and intake system for any blockages. It's also a good idea to check your engine's sensors for any faulty readings.
