Any thoughts on this sound?
Whenever I shift down a gear in sport manual mode in my 2026 M340, I hear this high pitched whine/squealing noise (almost sounds like air escaping) is this the turbo? Noise typically happens whenever rpm’s are dropping from 3000rpm and goes away when I press the accelerator OR if I press comfort mode.
Just want to know if other M340i owners have noticed this as well before I schedule a dealer visit
