I believe it has slow learn adaptations now... meaning the charging system does adapt to the aging process of the battery. And if a fresh new battery is thrown in the system won't charge it to it's capacity. Take that and add "efficient dynamics" to the mix where the DME tries to reduce load on the engine by not running the alternator on acceleration as much as deceleration and you have the German take on a charging system. It takes some trial and error with plenty of revisions before new ideas are ironed out to work properly, and software updates are most likely making it more robust judging solely by the reports of people not getting the "increased battery discharge" messages much after programming. (although there isn't official info confirming this)

I tried to save the E70 training manual from online, but only the introduction chapter came through... the energy management section has good info on this stuff that could be beneficial to the thread but I can't get to it apparently. Maybe if I try on the windows machine it will? I'll try again later.
