I had this issue a year ago. Dealer gave me the "
unfavorable driving profile" crap. I bought a new battery and their "BMW advanced charger." I plug the chrager in every few months, but the car would never take a charge. The red light would go on for a minute (charging), then switch to green, then shut off. Now I'm getting the increased discharge again. Gonna take it to the dealer and so help me god they give me the "unfavorable driving profile" crap again...stay tuned.
