I have a friend with an E46 coupe, and the inner panel of the moonroof is
The liner can be pushed by hand to expose the glass roof panel, OR the liner
will move on its own to accomodate the Tilt Feature of the glass roof.
In my friend's car, the liner can be taken out of the car when the roof is
tilted, and it MUST be moved by hand for any movment (other than full
opening of the glass roof). The liner does not move for the Tilt, nor does
it move for Close if the roof is open.
Somebody here posted a link to service the mechanism to the E36 roof, I used
this link to service my own car and the results were excellent. Is there a
link to do the service for the E46's roof?
It appears that the glass roof comes out by removing 3 torx screws along
each side, but before I set about working on a car-not-my-own, I thought it
would be nice to confirm my observations.
