What is the best way to diagnose and fix an engine misfire in an Audi vehicle?

I've been experiencing a slight misfire in my Audi A4 and want to know the best course of action to prevent further damage and get it fixed. The check engine light has also been on. Any insights would be greatly appreciated!

To diagnose and fix an engine misfire in an Audi vehicle, first connect a diagnostic tool to the car's OBD-II port to retrieve trouble codes and identify the specific cylinder causing the misfire. Next, inspect and replace spark plugs, ignition coils, and fuel injectors as necessary. Finally, perform a compression test to check for any internal engine issues. If the problem persists, it may be necessary to seek professional help from an Audi dealership or mechanic.
