i have the same problem with my 86 328i.
when the temp falls below 38 deg, I hear one loud beep and the temp option on the OBC lights up.
I have been getting random 3 beeps ocassionally too. I asked the dealership and they had no idea. I will try disabling the memo (speaker looking) feature and see if that does it. what is the thing about the speed and the beeping ? didnt get that.
