one of my 330's has been sputtering lately so i took it into bmw. they call me a couple of days back telling me bmw came out themself to look at it and that the motor is blown, dead, gone, and not under warranty....because it was "over revved." I drive my car conservatively (at least my 330s). they told me that it was cylinder two. i believe is a manufacturers defect...if it were to do what they say...shouldnt cylinder 2-4-6 be effected as welll????? i called them back to confront the situation and told them about that 3cyl would be effected and only then did they say, "yea 2-4-6 was bad, but two was the worst." they said it was probably because it was downshifted and over revved...which i don't do and even if i did it would take quite a few times to do some damage. the car has about 35k miles on it....what do you guys think about this? they want 11k + install. i told them my lawyer will be contacting them.
