40-50mph whine

[rgb129]

I have a whine that seems to originate up front starting around 40 and tails off close to 50. It doesn't do it coasting...only on light acceleration. In past cars this was from the differential. I had the dealer look at it and of course they said it is normal. I am almost due for the 40K service which does have them change the diff fluid. I am going to push hard after that change if the noise is still there.

Is there anything else that would cause this? Have any of you experienced this? The only other F10 M5 that I have been in did not do this.
