My sun roof seems to have come off the track on one side. when i try to open or close it, the glass buckles and makes a grinding sound. The motor of the sun roof seems to be working fine.I wasn't sure if anyone would have a diagram of VW sunroofs so i can fix the problem. I have looked for a VW repair guide but they are pretty pricey, and if i did want one, they are out of stock... please help!

caution if it opens you may not be able to close it again, this sounds like the track broke or something in the motor. lets hope its the motor as if its the track then the whole track needs to be replaced, there is no repairing a broken sunroof track.
the shade may be related to sunroof not closeing completely, the most common reason is the track is broken , this is the most common reason for when the sun roof doesnt close or jams when opening or closing its always the track breaks, the way to check this is to easy the headliner needs to be dropped and removed and then the glass from sunroof removed then unbolt track and drop down into car and check the track linkage and arms and track and see whats broken, note there are no replacement parts only motor or cable, as far as the parts that always break like an arm on the track this is not replaceable the track needs to be replaced, hope this helps , good luck.
It sounds like the switch has gone bad or that there is something wrong with the track. If you look on the inside of the sun roof you should be able to see four screws. These screws hold the sunroof in place and to the track. Take those screws out and then the glass. If you look down where the track is when the glass is out and push the button to open and close you should be able to see the track move. If you cant see it move when it is supposed to open pull the switch and see if you are getting power to the open and close side of the switch.
There is an "anti-trap" feature in your sunroof motor that will prevent the sunroof from closing if it "thinks" somthing is in the way.
The next time you have the problem, try helping the window by pushing it forward when you activate the close switch. This will tell us if the "anti-trap" is active. By helping the motor, it takes away some of the resistance and the motor thinks its OK to close.
If it works with your help, try cleaning the glass rails, sand, dirt, leaves and debris add friction to the system and cause a "false anti-trap".
Once cleaned apply the approved lubricant and work the window several times to spread the grease up and down the track.
Good luck and let me know.
make it go back to the open position,look down the side of the tracks in the roof that the sun shade slides in and you will probable find the guides for the sunshade are jamming up the tracks. only way to replace them<4 one in each corner> is to remove the glass section and then close sunshade that will give access to the 4 guides which are available from dealer as a kit
The sun roof has nylon gears that pulls the roof back and forward when activated. There is one on both sides of the sunroof track in the rear corners of the roof track housing. Unfortunately they are not replaceable by themselves and must be purchased as a unit for the whole roof track system. The cost of the replacement and labor to have it installed (if you can find someone to do it) is up to $1500 so isn't very practical to replace based on the value of the car itself. Better off to just work the broken piece out and manually put roof back in place in shut position and not use anymore, at least that was my experience with the one my daughter owns.
