As to service lights, the green bar is in relation to general service, oil filter changes, I assume you reset that using the round diagnostic socket in the engine bay by shorting two of the pins? If you are left with the clock face in the display this refers to the brake fluid change that should get done every 2 years. That has to be reset when done to extinguish the clock face icon. I use my scanner to do all the resets but you can buy a little unit that plugs into the round diagnostic socket that has three buttons, one for oil service and one for Inspection service and one for brake fluid change (clock face).
You will also need a 20pin to 16pin OBD2 cable changer to plug the unit in.
A decent OBD2 scanner should also be capable of resetting these indicators, Creator 310+ is a popular BMW scanner.
