2025 X3 M50 Horrible engine whine

[cedric514]

Hello everyone,

I am the proud owner of a brand new X3 M50 here. A little after two weeks of use I have started noticing the car was very whiny on acceleration mostly lower gears. So instead of the growl I hear the car make on youtube I have this god awful sound and it is tearing my soul... I have since went down the B58 engine whine rabbit hole and found the ZF8 gearbox could be the culprit. Has anyone experience something similar?

Here are the sound clips for reference:

Can't say I have. Has this been brought up to the service advisor?

I don't hear anything..sounds a bit less "boomy" than the B58 in my G02

Should be under warranty take it in.

I'd recommend to put the phone under the hood to record (just make sure it is secured there). I think I hear what you are referring to, the high pitch sound at higher rpms, most likely the sound of the turbo.

I here the whistle of the turbo. I just picked up an X3 M50 this weekend for my wife. Will listen tomorrow. It is definitely higher pitched than the X3M we turned in.
