I have a 545i 2005. A couple of weeks ago my BC Button quit working. It is one of the buttons on the turn signal arm. The only function the BC will do is reset mileage. I don't know where to start. Is there someone with experience on the BC Button. Thanks in advance.

The BC button is to call up computer information on the cluster.1st is ,,, Cruising range will give u an estimate of range with the amount of fuel in the tank. 2nd is,,, Average speed, 3rd is,, Average fuel consumption. If u hold the button down for three seconds in each function it should reset each function. I personally rarely use this button
