Z4 E89 diff noise puzzle

Did you manage to solve the problem?

I have exactly the same issue on my car[2011 3.5IS] and its got worse over the past 4 years. No garage so far has been able to give me a solution and I now avoid BMW because they simply cost too much. Paid over £2500 on my last visit for a roof issue. The car passes MOT with no advisories but the shooshing noise has just got worse over the years. Especially loud when its been stood for a while.

Hey, how's it going?

Sorry to revive this post, I just got a BMW Z4 E89 '09 sDrive 30i with 100k miles and it has the exact same noise you mentioned. Took it to a fine mechanic and he's quite sure it's the diff.

Could you solve your issue? Thanks for any update :)

It was the diff! Still sounded a bit noisy when testing but seemed to settle quickly and. been fine since. Fingers crossed!

Hi folks was this whooshing noise you describe there all the time or intermittent?

I get a very similar noise combined with a metal on metal "ting" but it happens every few seconds when I'm on the move

It doesn't seem to be linked to the auto box changing gear but I can't be certain
