Oh yes, it happens to me a few times a year. They changed 4 injectors for me. Service guy told me that the other 4 would act up soon but BMW didn't authorize to change all 8. It is happening to me now. The sneaky thing is that it always happens to me at night time or weekend, when the dealerships are closed. Next day, the problem usually goes away. So, when I bring it to dealership, they look at me like an idiot saying there is nothing wrong.
