Tools for installation

Note. Due to the brief processing time of the adhesive (total of 10 minutes), 2 adhesive sets DA 004 600 A2 and 2 double cartridge pistols VAS 5237 are required for the installation and 2 people must apply adhesive onto adhesive residue on body starting from the same point and working in opposite directions. The beginning and the end of the adhesive bead must be applied so that there are no gaps in the bead to assure proper sealing.

1. 2 x double cartridge pistols VAS 5237
2. Tensioning strap T10038

Materials for installation

Note. 2 sets of window adhesive DA 004 600 A2 for installing the roof module.

Removing the roof module

Scheme 6

1. Panel -1- Included with the roof frame Cannot be removed undamaged without removing windshield. NOTE: Once the windshield is removed, the entire roof module -11- can be removed without damaging the panel -1-. Removing and installing, refer to «SUNROOF PANEL»(ref-496129-S08336870672012082100000)
2. Panel -2- Removing and installing moving panel, refer to «SUNROOF PANEL»(ref-496129-S08336870672012082100000)
3. Panel -3- Already glued to module on a new roof module. Removing and installing, refer to «SUNROOF PANEL»(ref-496129-S08336870672012082100000) Dimension -a- = 5 mm between rear edge of glass panel and forward edge of sheet metal panel
4. Rear Panel Sheet metal panel It is not possible to remove without damaging it. NOTE: Protect the top of the rear lid near the panel from damaging the paint with two-sided table before removing. Bend the rear corner of the metal cover approximately 90° upward with pliers. Cut through the side of the adhesive bead -6- with a V.A.G 1561/22 on both side of the metal panel. Cut through the rear adhesive bead -6- with the V.A.G 1561/11 straight through to the vehicle. Bend the metal panel approximately 90° upward and cut through the front adhesive bead -6- with a V.A.G 1561/11 straight through to the vehicle. Dimension -b- = 4.5 mm with rear lid closed between rear edge of sheet metal panel and rear lid.
5. Rear Lid
6. Felt Strips Self-adhering, apply to the same location (Scheme 8)
7. Adhesive Bead for Sheet Metal Panel Cut back residual bead when installing a new panel. -- Cut flat the remaining adhesive material on flange using V.A.G 1561 and V.A.G 1561/10, do not remove all residue under any circumstances. -- Residual material acts as a base for the new adhesive sealing material. Apply at center on residual adhesive bead
8. Butyl Adhesive Sealing Cord After removing panel, remove residual butyl cord and apply a new one onto the same location again. NOTE: The butyl cord seals the panel from the body and must be absolutely tight. Route the ends so that there are no gaps. Diameter of butyl cord = 8 mm.
9. Supportive Beads NOTE: The support beads have been discontinued as of VIN 8 P5A 126 517. Cut back residual beads when installing a roof module. Do not bond the roof on these places. Use a 100 mm x 1 mm x 10 mm self-adhesive felt strip in its place.
10. Adhesive Bead for Roof Module Cut back residual beads when installing a roof module. Apply adhesive to body on the same location.
11. Sunroof Module Removal NOTE: The panel -1- will get damaged when removing the molding. Do not remove the headliner, but rather just lower it. Refer to «Removal and Installation»(ref-496058-S22585871132012082100000). -- Remove the trim on the A pillar; the sun visors, the grab handles, the rear roof trim panel and the interior lamps. -- Unclip the rear headliner in the center. -- Remove the headliner forward from the trim on the C- and D-pillars and lay it in the vehicle. Remove the crossmember for the sunroof. Refer to «SUN SHADE»(ref-496129-S04128108022012082100000). Remove roof trim molding «SUNROOF»(ref-496129-S20845077042012082100000) Cover thoroughly all neighboring body surfaces to sunroof module all around using fabric-reinforced adhesive tape to protect paintwork. CAUTION: Be careful not to damage the molding on the windshield when removing the molding on the panel -1-. Remove the molding on the edge of the glass with a sharp knife, on the front of the panel -1- and on the sides. Insert the V.A.G 1561/23 into the V.A.G 1561A and cut the adhesive beads on the roof module near the panel. Replace the V.A.G 1561/23 with a V.A.G 1561/22 and cut through the adhesive on the front of the roof module. Cut the side of the adhesive bead -9- along the roof up to the metal panel. Be careful not to damage the seal on the back of the cover -3-. Cut the adhesive bead for the roof between the cover 3 and the metal panel. NOTE: Cut through the support beads first if the vehicle has these. For easier access, remove the bolts form the cable guide. Refer to «GUIDE AND CABLE»(ref-496129-S17896209252012082100000). Cut through the left and right support beads with the V.A.G 1561/24. Install the bolts for the cable guide. Remove the complete roof off the vehicle with four people. NOTE: If there is any adhesive that did not get cut, use a cutting wire, part number 357 853 999 A and two pull handles V.A.G 1351/1 to cut through it now. (Scheme 10) Lift sunroof module (four people required) out of vehicle. Installing NOTE: If the same roof is to be reinstalled, then the remaining bead must only be cut just before installing. Cut back remaining adhesive sealant material on roof module and body flange using V.A.G 1561A and V.A.G 1561/10, do not remove all residue under any circumstances. Residual material acts as a base for the new adhesive sealing material. If windshield flange has been repaired or replaced, paint structure should be restored and if necessary, corrosion repair measures should be taken. Clean the surface with D 009 401 04 and then prime it with D 009 200 02. WARNING: Keep adhesive surface free of dirt and grease. Only cut back adhesive surface shortly before installation. Do not prime or use a cleaning solution on the adhesive surface. NOTE: Two people using two double cartridge pistols are required to apply the adhesive. Two window adhesive sets DA 004 600 A2 are required. When inserting roof, four people are required to lift module into vehicle and align. Install the spacer in the same place on the module (Scheme 7). For a new roof module, remove adhesive covers on spacers. Pull off cover strips on roof module adhesion surfaces. Clean adhesion areas with cleaning solution D 009 401 04. For a new roof module, apply primer D 009 200 02 to adhesion area on the module. Allow primer to air dry for 10 minutes. Apply the adhesive on the body side with a second person. CAUTION: Make sure there is a slight overlap at adhesive joining points, otherwise there may be leaks in these areas. Sunroof module must be inserted in the vehicle within a maximum of 10 minutes after start of application, otherwise the bonding properties of adhesive sealant material will be impaired. NOTE: When inserting roof, 4 people are required to lift roof over vehicle and insert into body. Insert roof module into vehicle. Distance -a- to sheet metal panel must be 5 mm. Press in roof completely onto spacers in roof cutout. Secure roof flush to body contour using tension straps at front and rear through the opened doors. For stronger pre-tension of sunroof module against vehicle, place plastic blocks (Styrofoam) onto panel 1 and panel 3, place T10038over it and tighten. After installing, perform a leak test before installing the headliner. NOTE: If a removed roof is reinstalled, panel 1 must also be installed in roof module «SUNROOF PANEL»(ref-496129-S08336870672012082100000).
