Sun Roof Calibration: 3-Series

Push sun roof button in up/tilt direction and hold. After about 20 seconds, sunroof panel will make a small down-up movement. Release button for no more than 5 seconds and push and hold it in up/tilt direction again. Sun roof will run through a full open and close cycle. Once this cycle is completed, initializaton and adaptation is complete.

NOTE: If motor runs in the wrong direction when pushing the button in the up/tilt direction, preventing proper initialization, get the sunroof to the closed position, and disconnect power to the motor for about 15 seconds. Reconnect the motor and start the initialization procedure again, and it should work properly.
