Over a OBDII link it'll take about 16 hours to update all the iDrive component firmware (there's 5 different components), you'll need to make sure you have a stable power supply connected to the car (not a battery charger) otherwise you'll risk trashing the CCC computer.
Ouch !!! 16 hours !!! The problem Will be my car battery... Not my computer one. and do you have a link to dl the last ista program ? What is the risk to update the firmware himself? Can I loose some options ?
