    Went and looked at an E92 today, everything seemed ok.

    Except I noticed a really loud whirring sound, which I think is from the rear. When I say loud, it was masking some of the engine and downshift noise.

    It sometimes sounds like its coming from the front or engine, but I am 90% sure its in the rear.

    When revving stationary, you cant hear it.

    It starts when you pick up speed near 30mph, and the noise gets faster and louder as the speed increases.

    The best way to describe it, is like a UFO flying saucer lol, and the faster you go the faster the whirring sound is.

    Its definitely rotary related, possible something from engine when rotating, but more than likely rear.

    I thought its maybe bearing related, or diff maybe? But when the steering wheel is locked it doesn't have that diff grinding noise Ive had on previous E92's.

    Anyone else had this or something similar?

    Hopefully it’s just the hub heat shield rubbing on the disc. Had to bend mine back a bit because of this in the past

    Spunds like tyre noise if they are getting toward the end of their life.

    I've never heard a flying saucer come over my way, but I've got a diff (for a manual) if you need one

    Yeah I mentioned this to a couple people today, and all said its quite possible its this.

    Tyre's looked ok, well apart from them being a mix of dunlop and I think pirelli.

    LOL, its a DCT. Thanks though

    I am guessing it needs to go on a ramp and dealt with that way? Or jack it up and remove the wheels? And rev it whilst its off the floor?

    Its not going to be fixed or looked before being sold unfortunately, so I'm not sure if I should take the risk.

    It drives and feels fine, as good as my previous 2. Surely if it was the diff, it would be noticeable not just audibly, but also when driving?

    Just to add to what Mattibo said about the disc shield, the trans tunnel heat shield can also touch the prop shaft knuckle making a similar noise. Worth eliminating both as they're 1 minute fixes

    Yeah I get that, the worst thing is she has started driving lessons now. So imagine the missus and a learner driver in the car correcting all the stuff you shouldn't be doing as a driver
