Curious if anyone uses the auto start stop? BMW admits in the manual that the constant start stop will prematurely wear down components, but yet offers that as an option anyway, which seems strange. I realize it helps with the overall mpg, but probably not good for the overall health of the car.
On another note, from the past week, I consistently hear a short, high pitched whine/squeal when I first start the car. Wondering if this is normal?
Finally, can you play music from your phone app (amazon music, etc) with the phone connected to the car via USB? The car recognizes the phone connected via USB, but doesn't play the music through the speakers. (Bluetooth works fine).
Thanks!
