I have a E46 2001 Convertible, and i have noticed that since it has got
cold outside..(oh by the way i live in the UK)...Every time i start my
car the on board computer beeps and displays a temperature? IE. +1.5 C.
what the hell is going on? is it telling me the outside temperature? i
mean, i know its already freezing when i get in the car so it cant be
that. its bugging me and i can't help thinking it mite be something
can you help?
Your car is telling you that it is cold, andthere could be ice that has
formed in all of the usual places.
Some people know all about ice, but are not aware that it might be cold
enough for ice to form. The car knows how cold it is, and it knows that when
it is about 36F outside in "normal" places, it could be cold enough in
ice-favored locations for ice to form.
They all do that sir. :-)
My E39 in the UK does the same.
It beeps if the outside temperature is 3 degrees Centigrade or lower when
you start the car, and is meant to warn you that there might be ground
frost, even though it might not actually be freezing.
The "beep" is just to make u aware that it is cold enough for ice to
build up on the roads.. (frezzing temp.) i think the trigger temp is
37F.. so thats what it is.. just a safety feature..
It is anything at or below 3C and it will happen if the temperature falls
below that as you drive along. The actual temperature is displayed (so you
see 1.5C when you start, but it could be -20C if you live in St. Petersburg.
This is normal operation.
Move to a hot country if you don't like it.

internet message boards around the world and ask, "Why does my car
'Ding' at me?"
Even my ratty old '88 does that.

My E46 does it, standard feature - not sure if it can be switched off ?
My 307 used to just display a warning on the info display and before
that my Mondeo had a flashing warning light that flashed for 0 secs
between 3 or 1oC, then a constant light below 1oC.
Handy feature but the beep can be quite alarming - especially for me as
the last time I heard such a beep for the first time in a car it was an
