Interesting info....
Right before I traded in my 2014 550 with the N63TU my local dealership kept calling me saying my car was sending them a signal that it was due for an oil change AND battery change. I thought it as odd when the lady on the phone said that since i've never had any battery warnings on the 550 with only 9K miles on it. I didn't care since the car went back to bmw to trade in for the X5......
