How to troubleshoot a faulty ignition coil in my Audi 80?

I've been experiencing stalling and misfiring in my Audi 80 and I suspect it may be due to a faulty ignition coil. What are the steps to diagnose and fix this issue? I'm relatively new to car maintenance so any tips or guidance would be greatly appreciated.

First, use a diagnostic tool to check for any error codes related to the ignition coil. If there are any, note them down for reference. Next, visually inspect the ignition coil for any signs of damage or wear. If everything looks normal, you can try swapping the ignition coils with a known working one from another cylinder to see if the issue is resolved. If not, it may be time to replace the faulty ignition coil with a new one.

Before jumping to the conclusion that the ignition coil is faulty, make sure to check the spark plugs and wires as well. If they are worn out or damaged, they can also contribute to stalling and misfiring. Additionally, don't forget to check the ignition control module and other related components for any issues. It's always best to rule out all other possibilities before replacing the ignition coil.
