Did you replace the spark plugs directly from BMW? It could be a couple things....and since the car isn't throwing codes it's hard to know. Carbon build-up possibly? It could be the HPFP....if your injectors and spark plugs, etc, have been replaced that's the only other thing I can think of that is fuel related. No rattling, or weird noises in engine bay?
