Had my F55 since november 2014 going well, loving the 1.5 petrol - fuel economy, performance all good.
Yesterday was a particularly cold evening and I saw a new warning message for the 1st time

battery was discharging

note in visual boast radio advised I needed to go on a prolonged drive and if this problem came back to visit a dealer.

I am not sure why this message came up but this morning it was not there.

Has anyone else had a similar event with their car and if so what did you do / find out.

please let me know
