    2018 340xi Possible Rear Differential Noise

    Hey everybody I just picked up my 2018 340xi over the weekend and cant be happier. From the dealership it was sounding great but after I got it home I started to notice it making a whining noise whenever I accelerated or braked. It happens from 0-50mph and doing some research online it seems like it may be a rear differential problem. The car only has 600 miles on it, but has anybody else experienced this problem? It just started today and I got off work after the service center was closed.

    Thanks

    Just got a call back from the dealership today and the car needed a whole new rear differential. Its ordered up already and should be installed by the weekend. I was expecting them to say they couldnt replicate the sound and send me away, so it was nice to see them handle it this way.
