Sunny: I drove alot more on weekends (a mix of highways and city roads) since the Nov 1 diagnosis. But exactly one month later, that message popped up once. The part that I don't understand is I drove far lesser before the diagnosis, and the message only showed up 7+ mths later. I drove alot more and it showed up one mth later after getting a full charge at the service center.
Someone told me even though battery is not under warranty but if it gives way within a year, the manufactuer, ie BMW may replace it. You heard about this before? I am going to continue monitor the battery situation, and purely run it on highways on weekends. If it shows up again within 1-2 mths, I will need to schedule another appt. But I still hope to find a solution to help me maintain it.
