My Ride: 2007 Bmw 523i (e60)
Default Engine Rattles at Idle

I have a 2007 bmw 523i e60 with an N52 engine. The engine rattles at idle but there is no “Check Engine” light coming on the dashboard right away, it inly comes on after some time. When it comes on, it tells me that there is a misfire in cylinder 6. I tried to change the place of the ignition coil and spark plug of cylinder six and used them on cylinder 2, but still the check engine comes on and the code indicates a misfire in engine six, even after replacing. What can be the issue?

Are you using any software like INPA to diagnose? what is the fault code you are getting? There could be various reason as SeanJordan20 indicated.
