How do I diagnose a BMW engine misfire?

My BMW engine is experiencing a misfire, what steps should I take to diagnose and solve the issue?

First, check for any error codes using an OBD-II reader. This will give you a starting point for troubleshooting. Next, inspect the spark plugs and ignition coils for any signs of damage or wear. If those are in good condition, you may want to check the fuel injectors and fuel filter for clogs or malfunctions. Finally, make sure the engine's air filter is clean and not restricting flow.
