Short metallic whine around 2-2.5k rpm on a frozen cold car
Hi, it's been -20 -25 celcius here lately and I noticed that when I drive with the car really cold, there's a short metallic whine around 2-2.5k rpm. Its like its about to change gears and then I hear a slight EeeEEeE metal whine noise or chirp, or whistling,, hard to explain. Lasts a few secm does it for a couple of minutes until the car has heated, and then gone.
What could be causing this? Seems related to engine rev and gears

I think you should start warming up your car a bit. Just run out 5 mins before you leave and warm it up. then see if you have these issues. Cold temps do a number on your car, so I suggest warming up and seeing if the issue seems to fade a bit?

not to get off topic but I thought BMW just programed the ECU to not shift or rev past a certain RPM until the car has reached operating temp

When its that cold out and your car has been sitting for a long time (overnight) its not uncommon to hear a whine initially when you start your car. All my cars have done that in the winters, and it eventually dies down as your car warms up (usually 1 min it will stop whining).
If you can plug your car in, it will help out a lot to prevent the whining and its a lot better for the car.
