How to diagnose a faulty ignition coil?

I have a BMW Series 5 and it's been stalling a lot recently. I suspect it's a faulty ignition coil, but I'm not sure how to diagnose it. What are the steps I should follow to determine if it's indeed a faulty ignition coil?

First, you should check for codes using an OBD-II scanner. If you get a misfire code, it could be a sign of a faulty ignition coil. Additionally, you can visually inspect the ignition coil for any signs of damage or wear.

You can also use a multimeter to perform a resistance test on the ignition coil. Compare the readings to the manufacturer's specifications to determine if the ignition coil is within tolerance.

If you're still unsure, you can swap the suspected faulty ignition coil with a known working one and see if the issue remains or moves to another cylinder. This will confirm if the ignition coil is the culprit.
