Yo guys, will urs F30's side mirror flip/ turn down and show the lower of the ground/ rear tyre part while u reversing?Today i just noticed that the side mirror of my F30 only flip/ turn down on passenger side, the driver side remain the same angle while im reversing. And when i turn the side mirror adjust button to the left, both of the side mirrors remain same angle and doesnt flip/ turn down to show the lower ground.Is that a norm?
