How to troubleshoot engine misfire on my Audi A4?

I have a 2019 Audi A4 with a 2.0T engine and it recently started misfiring. I'm noticing a loss of power and a rough idle. I've changed the spark plugs and checked the coils, but the issue still persists. What could be causing this and how can I fix it?

It's possible that the misfire is being caused by a clogged fuel injector. Try using a fuel system cleaner and see if that helps improve the performance. If not, you may need to replace the injector.

Another common cause of engine misfires is a faulty ignition coil. Even if you've checked them before, it's worth double checking and replacing any that show signs of wear or damage.
