How can I fix my BMW 5 Series' faulty ignition coil?

I have a 2016 BMW 5 Series and recently noticed that my car is misfiring and having trouble starting. I suspect it might be an issue with the ignition coil. What steps should I take to troubleshoot and repair this problem?

First, you should confirm that the issue is actually with the ignition coil. You can do this by using a code reader or taking it to a mechanic for diagnosis. If it is indeed the ignition coil, I suggest replacing all of them at the same time to avoid future problems.

Another thing to consider is checking the spark plugs and wires for any damage. If they're worn out, it may be a good idea to replace them along with the ignition coil.

You could also try cleaning the ignition coil before resorting to replacement. This may help improve its performance and save you some money.
