Be careful, as I've had N54's almost hydro-lock on me from fuel leaking into the cylinders from injector failure.
Thanks bmwm.d, I know from your posts you're extremely knowledgeable. I was getting a misfire on cylinder 4 multiple times it was only that cylinder. I had the car towed to the dealership and at minimum I'll pay the diagnostic fee and hopefully that will narrow down the issue.

What about the squeal at first? And is there any possibility of 02 sensor? I thought the 09s and laters had the updated injectors and less prone to issues.
