How to troubleshoot an engine misfire on an Audi A5?

I have been experiencing an engine misfire on my Audi A5 and I'm not sure where to start troubleshooting. The car feels sluggish and there is a noticeable loss of power. What steps should I take to diagnose and fix this issue?

First, check the spark plugs and ignition coils. These are common causes of an engine misfire. Make sure they are in good condition and replace any that show signs of wear or damage. Also, try using a fuel additive to clean any buildup in the fuel system.

Another possible cause of an engine misfire in an Audi A5 is a faulty mass airflow sensor. This can lead to improper air to fuel ratios and result in a misfire. Consider having the sensor checked and replaced if necessary.
