Hi, have a 2004 260 SE saloon with e/sunroof. it wont self park or operate fully. i have tried resetting it and after 45 secs it clicks and parks in the tilt position rather than closed ?? is this normal.

the roof tilts fine but wont tilt close into fully closed position, it either closes then slides back open or you have to click it closed bit by bit. when roof wentto slide back it stopped half way like it was stuck or struggling then switch wouldnt operate, fuse okay. had to close with allen key and then it will partially work again on button

any help advice appreciated

thx James
