I use the cigarette lighter plug as a Power Adapter for Cell Phone / Tablet. The plug only has power when the engine is running. Is there a way to modify this and make it "hot" all the time? I would like to charge accessories while out of the vehicle.
OK - Soapbox time ***
I would like to thank BMW for the Inteligent decision of making the cigarette lighter socket / accessory power outlet only usable while the engine is running. Heaven knows I would never ever need to leave my cellphone in the vehicle to charge while the engine is off. I would never want to use it to power an accessory during my break without starting the engine. I would never want to use a trickle charger to keep the car battery charged while it is sitting in the garage for an extended period of time.
However - if it ever breaks - I am sure that the extra electronics that it takes to make it function will not cost much.
Sorry for the rant - but when people that are supposed to be very smart come up with extremely stupid ideas - I sometimes get upset.
It might be to prevent children using the cigarette lighter when unsupervised and burning themselves or the car. I know of a firend who has a Tarago with a live lighter socket, and one kid ended up with a lighter shaped burn on her forehead when her brother did exactly this. Might not be as dumb as you might first think.
