I have the same problem.
I believe battery is charging ok, it's just that when coasting that blue light does not come on (never) and it's been going on for months. Amyone know how I can get this blue light come on again? |

Why do you think the battery is still charging? Is your foot on the throttle even just a little? A trip to the dealer or indy is probably your next step. |

Assuming you have an AGM type battery (which all of us with F10s seem to) then it should measure 14.8VDC when it is charging at max rate. You should see this at some point when the car is running. This is a system voltage which will recharge the battery as quickly as it is able. A voltage suitable for "float charge" when the battery is near fully charged is more like 14VDC. |
