Some fixya user told me a website reliablestore it is very good.. I used it to repair my shredder it had some spark issue which wasn't easily fixed. you can go there and try

most likely they control mechanism is a bit stiff/dry , if the roof will move forward spray wd40 up each side runners etc go back and forwards a bit at a time ,this should lubricate the mechanism and hope fully save ypou having the roof stripped out to solve the problem

One of the plastic clips have broken, you can google a fix for that, I did mine not too hard to do. Price aprox 75$

some of the cable operated sun roofs stretch making the timing of it out of wack, id drop the headliner and watch for any odd movements while it is closing.....

Have window closed. Press the vertical vent button (press in towards roof). Hold for 20 seconds and the window will start to open, keep holding button until the window goes all the way back and then all the way forward. BMW's initialization procedure.

I just had the same problem... the rear glass has 2 suports, which you will need to insert a long screw driver in it and force them back manually... It's a pain, but I can get you all the pictures to this procedure...

Am I correct in assuming that you have an electric roof? I recently saw in my manual that there is a hydraulic lift that you can access from the trunk of the car. It looks like it is on the left side wall close to the opening. The following is taken directly from the manual:
"If the power system is not operating properly you can still close the roof by hand. 1. Remove protective cover and open luggage compartment lid. 2. Turn screw on hydraulic pump counterclockwise until it stops. 3. Close the luggage compartment lid. 4. Swing the top forward by grabbing it with both hands, lift and push it forward. 5. Lock roof in place. 6. Turn the screw on hydraulic pump clockwise until it stops. Use the same procedure in reverse order to open the power roof manually."

title says X5, but description says X3. i'll explain for an X5, but X3 with the pano should be the same. and i'll explain function of the roof, not reprogramming.

button is located on the panel at the top near the front & center windshield. its the switch on the far left on this panel. its a switch that not only toggles, but also slides forward & back.

with your finger in front of the button, slide it back & release. this will make the cover slide back and store revealing the sun roof. you know have 2 options (tilt the sunroof up or open the roof completely).

to tilt it up, press up on the rear of the button and release. the rear of both roofs will pop up. to close, push up and release the front of the button or slide the switch forward.

to slide it open completely, repeat what you did to open the protective cover (slide the switch from front to back). the roof will open completely and stow out of the way. to close, slide the switch forward and release. pano roof will now close.

to close the cover, slide the switch forward again.

neat trick: if you want to tilt the sunroof open without opening the protective cover, press up on the rear of the button (when the cover is closed) and release. the cover will separate in the middle exposing about a 2-3 inch mesh, then tilts the sunroof open. to close, push the button forward again.

also, if you are above a certain speed (can't remember what it is off hand) with the sunroof open or tilted, it will close automatically, then perform the neat trick on its own to keep air coming in.

one last trick: if you want to open the windows and sunroof from outside, press & hold the unlock button (forward button on the key) and you will see the windows go down, then the roof will open to vent. releasing the button will stop the motion of the windows & roof.

hope this answered what you were asking.

Ha, i just replaced one of these today. Yes they are serviceable but a pita. There is also a fix for the rear glass not closing. The rear tilt mechanisms need to be replaced bmw part number 54 13 7 240 682.
