W211 passenger seat will not move fully back or fully incline
 

The passenger seat will not move fully back or fully incline. It is about half of what it should be in both situation. It can move back or incline but stop halfway thinking it has reached the end limit positions. The door switch should be ok as all directions can be activated. I suspect the calibration of the end positions are out of whack. I removed the passenger seat fuse at the dash but to no avail. There is another fuse in the trunk but I hesitate to remove it. I don't know what they do. Do I need to take it to the dealer?

The car fixed itself! After a few days, the seat is back to normal again. The fault seems to have timeout. It can now move fully back or recline. Very strange, too many computers with modern car.
