I'm an old schooler of BMW"s . I've just bought a 2013 328 fully loaded . Now I'm worried about this turbo engine noise I keep hearing about it . I don't have the car yet it is being shipped from another state . It is a 6 speed , I despise the automatics . Is this thing going to be that loud knocking , whining , ?? I'll go crazy ! It was made in April 2013, I DK if thT matters or not in regard to the engine noise . I was so busy researching options, trying to find a car with what I wanted I failed to research the turbo until after the fact !!!! Now I'm really I panic mode !!!
