Technical Service
SUBJECT
Sunroof Moves in Small Steps or Interior Lights not Working
MODEL
E90, E91, E92 (3 Series)
SITUATION
The sliding sunroof moves only in small steps, or the interior lights are not working.
CAUSE
The Roof Functions Center (FZD) is not initialized, or has lost its initialization.
CORRECTION
Re-initialize the FZD.
PROCEDURE
Switch ignition on (KL-15). Starting with the sunroof in the closed position, press and hold the sliding sunroof switch in the "Tilt" direction (the switch must remain pressed for the entire procedure). After approximately 20 seconds, the sunroof will start its initialization by first storing the end position for the "Tilt" position, then moving to its fully open position, then fully closed position, and storing the end position in each case. The total time for initialization is approximately 120 seconds.
In the unlikely situation that initialization is unsuccessful, carry out an FZD reset by removing fuses F5, F12 and F28 from the front fuse carrier (behind glovebox). Replace the fuses, then recode the FZD - refer to SI B09 05 01 (Coding, Individualization and Programming), procedure E. Then restart the initialization procedure as described above.
