i'm a little curious about this. i've searched up and down this website and others trying to find an answer. alot of us that have a digital climate controls (98' 230) know that we can check certain things on it. ok, so here it is, today i'm driving and i notice that my radar is showing a low batt. voltage, so i check it with the A/C. Everything is fine so, while i was checking it i decided to turn off the EC, so the air could turn on. i noticed that the EC light wouldn't turn off, so i held the button, and after about 2 sec. the menu changed again, to 2 little letters, A and B.
moving the arrows (red and blue) changed some symbols about three times before returning to the original symbols just the A and B.
this is my question, does anybody know what those letters mean and what gets changed by moving the arrows?;)
