My panoramic roof is stuck in the fully open position. The sun blind is OK. The re-sync procedure does not work. Can anyone help.

Sun blind re-sync

The re-sync procedure is in the owners manual.
For the R500, remove and replaced the panoramic fuse - located in the rear RHS fuse box - number 42 I think on the R500. Turn the ign. key to position 1 and close the blind - hold in place for 2 seconds - open the blind and hold for 2 seconds. Ignition off and on.
Last time took me 3 attempts but eventually it worked.

On my R500 there is no crank to manually reset the panoramic roof. The local MB dealer (Rafih in Windsor Ontario Canada) closed the roof and charged me the standard diagnosis cost which is reasonable to me.
