Rear end (diff?) whining noise...anyone have the same?

Waking up an old thread as I am experiencing what sounds like diff whine. Was this issue ever resolved?

Yes, i described the fix in the post immediately previous to yours... gearbox replacement. No idea of root cause, it went back to BMW GmbH and that's the last i heard of it

Got ya thanks. Sure that’s way more expensive than a new diff so I’m hoping mine doesn’t go the same way

If it's the rear diff was the oil changed at regular intervals at dealer..important on these.

I bought the car with 48000 kms on the clock. It now has 70k. I’ve had the oil changed once since buying. Unfortunately don’t know about the period prior to my ownership
