Just bought a 328i, my first BMW, and 100 miles into driving it home, I heard a beep, and the message center showed 40 F. This is in 90 degree weather! Now the trip odometer will not reset when you push the button, and I stil get 40 F whe I cycle to outside Temperature. It also shows 40 C if you change the scale. Any ideas?
I'm mechanically minded.
