more engine noise stuff.
in my almost 2-1/2 year old Cooper, i've begun to become aware of a strange "growling" noise when accelerating hard from 1st to 2nd to 3rd (like when getting onto the freeway from a dead stop) which was not audible in the past. very low pitched, seemingly from directly under the car, and it stops when the revs come up. assuming i'm not imagining this, does anyone have an idea as to what it might be? i suspect something's vibrating, possibly. since i have to take in into the dealer next week for some other stuff, i wanted to mention it but don't want to sound like the technical idiot i am.

thanks,

paddy

 

I realize you wrote this quite a while ago, but if you're getting this message, did you ever resolve this sound at the dealership? I am experiencing this very same issue. Thanks.
