Rough idling
Lost of power
Engine malfunction indicator (car goes into limp mode)

Hope this helps.
I had a couple of instances of exactly what you describe. My dealer changed one spark plug, swapped a couple of ignition coils, and cleared the faults. It happened again a couple of weeks later, but that was five months ago.

Since then, the idle is a teeny, tiny bit lumpy (barely noticeable) and once in a while, starting it up takes a lot more cranking than usual.

And it's a 2011 550i, like yours. Any other '11 550i drivers having similar experiences?
