I have a strange problem which that I am planning to get checked out by a BMW diagnostic center, but wanted to know if anyone knows or had anything similar?

About a week ago I noticed that the outside temperature is showing the wrong temp (usually around 0F to -15F). Also around the same time when the temp went to below zero almost all of my electrics malfunctioned... But not every single time. (See attached images of malfunctions)

If I park the car in my garage and come back to it a few hours later, the temp is fine, but when I drive sometimes it comes back and all the malfunctions happen.

I live in Brooklyn, NY and my car is out of warrenty, so if anyone know of a good and trusted BMW repair / diagnostic place please suggest...

Any help would be greatly appreciated.
