Brought it into dealer, they diagnosed as misfire again (different cylinder) and contacted BMW for next course. They ended up replacing spark plugs and updated software (feels great now, by the way), but no replacement of injectors or HPFP. Picked it up after 2 days of diagnostics, next day it happened again! SA said they need the SES on for further action. Very frustrating. By the way, stuttering happens when the gas is pressed, so the power is low and causes the car to vibrate like an unbalanced tire.
Yeah, that's the exact problem I was having. The stuttering is when you press the gas.

I think it's crazy that they refuse to do anything until you get another SES. The car is clearly not working properly and it should be fixed. I would complain until they decide to fix it. This is unacceptable.

Can you keep us updated as to how BMW resolves it in the end?
