How to troubleshoot a misfiring engine in an Audi A4?

I have been having trouble with my Audi A4's engine misfiring. What could be causing this issue and how can I fix it?

First, check your spark plugs and ignition coils to see if they are worn out or faulty. If so, replace them as necessary. You should also check your fuel injectors for any clogs or malfunctions. If the issue persists, it could be a sign of a more serious problem with your engine's compression or timing. It is best to take your car to a certified mechanic for further diagnosis and repairs.
