More N63 bad news? So solution to battery charge flaw
So the BMW engineering solution to the battery charge design flaw -- it only charges during braking, by design, and not at other times which represent 99% of the use case of US drivers and they did this to get better gas mileage numbers -- is to replace the battery when they change the oil.
Do we have an option of getting worse gas mileage (the reason this design was implemented) to hold on to the battery?
I am going off warranty end of year and a new battery at every oil change adds some $600 to the costs if I adopt that solution. I'm already dusting off the trickle charger I used to use for the always out Wrangler.
