Removing
• It is not possible to remove the trim without damaging it.
• A second technician is required for detaching the adhesive beads.
• The new trim is delivered as a replacement part complete with all of the seals.
• Reuse the previous dimensions when installing the new trim.
Perform the following:
- 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.
- 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 trim are made accessible by removing the edges on the trim.
- Thread in with the cutting wire - 2 - on the front left between the trim - 1 - and the frames and secure the ends in two pulling handles (V.A.G 1351/1) - 3 -.
- Cut through the side and rear adhesive beads - arrow a - using "sawing" movements.
• There are 3 adhesive beads on the rear roof crossmember that require more force.
• Guide the cutting wire close to the trim so that none of the underlying components become damaged.
- Thread the cutting wire on the right in the front between the trim and the frame and secure the ends in the pulling handles (V.A.G 1351/1).
- Cut through the adhesive bead on the side using "sawing" motions - arrow b -.
- Then cut through the adhesive beads on the front roof crossmember in the same way - arrow c - and remove the trim from the frames.
• There are 2 adhesive beads on the front roof crossmember that require more force.
Installing
• Keep the adhesive surfaces on the frames free from debris and grease.
• Only cut back adhesive surface shortly before installation.
• Do not prime or use a cleaning solution on the adhesive surface.
Perform the following:
• To prepare enough of the assembly adhesive, 2 cartridges should be heated up.
• A second mechanic is required to apply the assembly adhesive.
- Install the wind deflector. Refer to => [ Wind Deflector ] Wind Deflector.
- Install 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.
• The installation must be performed with the glass panel closed.
• The location of the adhesive beads - 1 - is imprinted in the trim - 2 -.
- Cut back the remaining adhesive from the sunroof just before installing.
- Lightly sand the adhesive surfaces on the trim with fine-grain sandpaper.
- Clean the adhesive bead area on the trim with the cleaning solution. Refer to Parts Catalog.
- Prime the area for the adhesive bead with glass/paint primer (Refer to Parts Catalog) and let it dry for 10 minutes.
- Apply the assembly adhesive on the glass/paint primer. Refer to the Parts Catalog.
The width of the adhesive bead is 8 mm, the height of the adhesive bead is 12 mm.
- Attach the trim to the windshield, insert it into the roof opening and slide it toward the rear until the distance between the rear lid and the trim is 5 mm.
- Center the trim between the left and right roof pillars.
- Secure the trim with the adhesive tape and wait the minimum curing time.
Minimum Curing Time
• Only use the assembly adhesive listed below to install the trim.
• This adhesive was chosen due to its elasticity and does not cause scratches in the painted trim after hardening.
• The vehicle can only be used after the minimum curing time has elapsed.
