Removing
Perform the following:
- Remove headliner..
For a new frame
- Remove the glass panel for the panorama sliding/tilting sunroof, refer to => [ Glass Panel for Panorama Sliding/Tilting Sunroof ] Glass Panel for Panorama Sliding/Tilting Sunroof.
- Remove the wind deflector. Refer to => [ Wind Deflector ] Wind Deflector.
- Remove the guide rails and the mounting carrier, refer to => [ Guide Rails and Mounting Carrier ] Guide Rails and Mounting Carrier.
- Stick the seal on the windshield firmly to the windshield.
Apply adhesive tape around the borders of the body surfaces for the panorama sliding/tilting sunroof trim as protection from damages caused by paint.
- Make a mark spanning the entire length of the trim traveling outward from the roof pillar on the left and right in the distance - a - = 20 mm.
- Make another marking with a distance of - b - = 20 mm from the windshield outward.
Use a depth stop with the setting at 5 mm due to the narrowness of the opening between the trim and the frame.
- Cut the trim strips along the markings using the window cutter (V.A.G 1561A) - 1 - and the blade, 80 mm in diameter (V.A.G 1561/26) - 2 -.
The adhesive beads for the frame are made accessible by removing the edges on the trim.
For a frame that is going to be used again
- Remove trim. Refer to => [ Trim ] Trim.
- Remove the guide rails and the mounting carrier, refer to => [ Guide Rails and Mounting Carrier ] Guide Rails and Mounting Carrier.
Continue for a new frame and for a reusable frame
- Carefully poke the awl - 1 - (i.e. (V.A.G 1474/2) ) through the bead of adhesive from the inside to the outside as illustrated.
- Thread one of the ends of the cutting wire in the awl and pull it through the adhesive in the vehicle interior.
- Secure a pull handle (V.A.G 1351/1) on both ends of the cutting wire.
- Cut through the adhesive beads on the frame using "sawing" motions and remove the frame.
• There are 2 adhesive beads on the front and rear roof crossmembers that require more force.
• Separating the adhesive beads is only possible with the help of a second mechanic (one person pulls out while the other pulls inward)
• Guide the cutting wire close to the assembly frame so that none of the underlying components become damaged.
Installing
• The trim is already attached as are the guide rails and the assembly carriers are installed for a new assembly frame.
• For an assembly frame that is being used again, residual material acts as a base for the new adhesive sealing material.
Perform the following:
- Inspect the frame for damages and replace it if necessary.
For a new frame
- Install the wind deflector. Refer to => [ Wind Deflector ] Wind Deflector.
- Install the glass panel. Refer to => [ Glass Panel for Panorama Sliding/Tilting Sunroof ] Glass Panel for Panorama Sliding/Tilting Sunroof.
- Grip the frame with a suction cup on the glass panel.
- Cut back 1 mm of the remaining adhesive bead on the front and rear roof crossmember and on the left and right roof pillar just before installing.
- Clean the adhesive bead areas - 1 - on the frame - 2 - with cleaning solution. Refer to Parts Catalog.
• The location of the adhesive beads - 1 - is imprinted in the frame - 2 -.
- Prime the area for the adhesive bead with glass/paint primer (refer to Parts Catalog) and let it dry for 10 minutes.
- Apply the 2K window adhesive on the glass/paint primer. Refer to the Parts Catalog.
The width of the adhesive bead is 7 mm, the height of the adhesive bead is 10 mm.
- Install the frame in the roof opening, center it and secure it with adhesive tape.
- After the minimum curing time elapses , reattach the following components from the previous frame to the new assembly frame:
• Electrical drive motor, refer to => [ Motor for Panorama Sliding/Tilting Sunroof Glass Panel ] Motor for Panorama Sliding/Tilting Sunroof Glass Panel
• Sun Shade, refer to => [ Sun Shade ] Sun Shade
• Sun shade cover, refer to => [ Sun Shade Cover ] Sun Shade Cover
- Install headliner.
For a reusable frame
- Install the guide rails and the mounting carrier, refer to => [ Guide Rails and Mounting Carrier ] Guide Rails and Mounting Carrier.
- Install the wind deflector. Refer to => [ Wind Deflector ] Wind Deflector.
- Install the glass panel. Refer to => [ Glass Panel for Panorama Sliding/Tilting Sunroof ] Glass Panel for Panorama Sliding/Tilting Sunroof.
- Grip the frame with a suction cup on the glass panel.
- Cut back 1 mm of the remaining adhesive bead on the front and rear roof crossmember and on the left and right roof pillar just before installing.
- Cut back the remaining adhesive bead 1 mm on the frame just before installing.
- Apply 2K window adhesive to the adhesive beads that were cut back on the frame. Refer to => Parts Catalog.
The width of the adhesive bead is 7 mm, the height of the adhesive bead is 10 mm.
- Install the frame in the roof opening, center it and secure it with adhesive tape.
- Install the following components after the minimum curing time has elapsed:
• Connect the connector to the electric drive
• Trim=> [ Trim ] Trim
• Headliner.
Minimum Curing Time
• For safety reasons, use only the electrically non-conductive 2K window adhesive when installing the frame.
• The vehicle can only be used after the minimum curing time has elapsed.
