    Hey Experts,

    I've just brought a second hand Mini Cooper S 2007 turbo and am really enjoying the drive. It has 51k miles but appears in good shape. However, I'm noticing a odd whirring sound when I drive above 40 coming from the front of the car. It gets louder between 40 and 55 and then just stays the same. If I put my foot on the clutch it makes no difference to the sound. The only that can make it a little louder is if I put the brakes on.

    I've posted a video but as I've a crap phone you can't hear it as loudly as it sounds in the car. Does anyone have any ideas what it could be? I've taken it to my local garage and they can't see anything wrong with the transmission or bearings. I know nothing about cars but it sounds like a circular, repeating sound. See if you can hear it.

    Here is a link to a video I took trying to capture the sound.

    Welcome, thanks for joining Motoring Alliance, the FUN and Friendly MINI Community.

    Have you given the brakes a good looking over?

    I've seen things like a rock get stuck and make a noise.

    Is it a good consistent whine once you get around a specific RPM?

    I had a very similar thing happen to me recently, and luckily I'm still under warranty for now. Turns out there was a gasket that failed on the the passenger side of the engine and was leaking down onto some pulleys and a belt. Dealership replaced the gasket, pulleys and belt and no more noise. Though I imagine that you could replace the gasket and belt and clean the pulleys for the same result.

    Just replaced the front brakes (as I thought that might be it), back breaks are fine. So am I right in thinking this sound isn't normal?

    It starts vibrating, whirring between 45mph upwards. Only really making a difference in sound when braking - humming/whirring sound slightly deeper.

    Apok did you car make a similar sound to my video?

    That sure isn't normal. Are you feeling the vibration through the steering wheel? Through the brake peddle when you stop? I think you should be revisiting the brake job.

    Brake Job double check, maybe a wheel bearing starting to go bad. :idea:

    I don't think it would be a tire out of balance but anything is possible.

    I just played your video again, and just for giggles try rotating your tires. Maybe you have slipped a belt or have Kumho tires.

    When I had Kumho tires they would get flat spots from sitting only after a few hours and make weird sounds when driving and different speeds.

    Could be a wheel bearing.

    I'm thinking wheel bearing.

    I'd have a friend drive along beside me on a non-busy stretch of multi-lane with their window down, and see if they can isolate which side it's coming from.

    I think it could be a wheel bearing also but I would definitely check or rotate your tires first.

    What brand of tires do you have ?

    Diagnosis:
    1) have a friend drive along beside (SAFELY) at the symptomatic speed, see if you can isolate side - and ensure it really is only coming from the front, and if it really is only coming from one side.
    2) Cross-rotate tires LF-RR, RF-LR, repeat test. What happens? If symptom moves... tires. If symptom stays put... probably wheel bearing (or maybe CV or brake).
