BMW 135i annoying whistle from engine
Just recently I noticed a whizzing whistle sound while in drive so I decided to open the bonnet and check what it is but I can't seem to understand the cause... Anyone have any ideas what this whistle may be?

Turbo spool is also all I could hear. You hear the turbo slow down with a slight delay on the engine rpms.
My 9 yr old daughter heard mine spooling up the other morning and asked why our car sounded like when an airplane is taking off edit: Actually, come to think of it, if you had a 2 series you'd likely be hearing that sound through your speakers too.

That's it! on deceleration it sounds like there is a whistling sound... Been to the dealer and they say it's normal but I'm not fully convinced. What do you think this is?
