Hopefully this is the right place!

I have a new (to me) 2016 F31 335D (55k miles) with a little whine/noise when between 60-70mph. Its still under warranty and i've taken into BWM who have changed a wheel bearing but the noise is still there.

doesn't matter if i'm coasting or gas applied. the noise is there. if i go under or over it goes away. Also had tyres changed and tracking done too.

Could it be diff or something?

hi,
i had a similar noise, whine like bearing noise and it was my runflats, changed to non runflats and alot more comfortably and quiet

the side it sounds like it's coming from I've changed both front and back tyre. also I'm not on runflats too. ps4s

to explain the noise it sounds like the engine is reving higher than it is.

bit of a guess but, have a good check for any loose plastic items, undertray, front bumper,
air box, battery tray , etc,
could be a resonance caused by wind vibrating something at the certain speed!

I was possibly thinking this too.

It's going back in for BWM to find, as they've changed the bearing i'm sure they'll find something different. i hope...
