Removing

Note

  • The trim panel of the sliding/tilting sunroof is destroyed during removal.
  • The removal of the trim panel of the sliding/tilting sunroof remains when cutting up the adhesive sealant material (PUR) between the trim panel and the sliding/tilting sunroof frame.
  • The -arrows -identify the position of the adhesive sealant material.
Caution

There is a risk of blocking of the drainage ducts of the sliding/ tilting sunroof frame.

  • Before starting to cut the visor close off the drainage ducts on the frame of the sliding/tilting sunroof with a suitable material.

Sunroof

  • Protect the surface of the panoramic window -2- in the vicinity of the trim panel of the sliding/tilting sunroof -1- with masking tape.
DANGER! Risk of injury.
  • Mark the surface of the trim panel with a sharp tool according to the following specifications:
    • -a- = 10 mm Marking parallel to inside edge of the trim panel.
    • -b- = 10 mm Marking parallel to front edge of the trim panel.
    • -c- = 10 mm Marking parallel to rear edge of the trim panel.

Sunroof

Caution

When cutting the trim panel there is a risk of damaging the sliding/tilting sunroof.

  • Due to the tight clearance between the trim panel and the frame of the sliding/tilting sunroof the Ø 80 mm saw blade - V.A.G 1561/26- must not cut deeper than 5 mm into the trim panel. Attach a limiter (stop) at 5 mm depth.
  • Using the electric cutter - SAT 1561A- and the saw blade, Ø 80 mm - V.A.G 1561/26- cut the trim panel open:
    • Along the longitudinal marks from the back to the front.
    • Along the transverse markings on the front of the trim panel (front and rear marking).
  • Remove the cut-off pieces to reach the adhesive material of the trim panel.
  • Using the electric cutter - SAT 1561A- and blade 207 - SAT 1561/12- cut open the adhesive material on both sides from the back to the front.
  • Also cut open both adhesive material strands on the front of the trim panel.
  • With help from two cable holder knobs - VAG 1351/1- with cutting thread - 357 853 999 B- insert the thread via the completed cuts in the front area, and pull alternating on both knobs until the adhesive material string is completely removed.
  • Remove the trim panel of the sliding/tilting sunroof.

Caution

The trim panel of the sliding/tilting sunroof delivered as a spare part has the following features:

  • The position of the adhesive bead is indicated by the reference line which makes applying the adhesive sealing material (PUR) easier.
  • The adhesive area does not have a layer of primer.

Note The panoramic window must be closed during installation.

Only in case of reusing an undamaged sliding/tilting sunroof.

  • Prepare the sliding/tilting sunroof frame for this purpose:
Caution

If an undamaged sliding/tilting sunroof is reused, the adhesive sealing material strings (PUR) must be cut back.

The adhesive material strings are cut back shortly before reinserting the sliding/tilting sunroof frame. If an adhesive bead is not applied to the frame immediately after being cut, this must be "activated" with the glass activator - D 181 802 M1- .

  • Shortly before applying the adhesive to the window, cut back the adhesive bead stuck to the window to a height of 1 to 2 mm.

Sunroof

Note

  • In areas with tabs, as displayed in the figure, the adhesive material must be cut back until it is flush with the upper part of the tabs.
  • The remaining material is required as a base for the new adhesive sealing material (PUR).
Caution

The bonding surfaces must be free of dust and grease.

Do not apply primer to the previously cut-back adhesive bead and do not treat with solvent.

  • Attach a rope -2- in the upper area of the window -1- underneath the sealing lip -3-.

Sunroof

Note

  • Keep the rope in this position until the bonding process for the sliding/tilting sunroof frame is completed.
  • The rope is used to reposition the lip in reference to the sliding/ tilting sunroof trim panel.

Continue in case of reusing an undamaged or new sliding/tilting sunroof frame.

Prepare the new trim panel for mounting. Follow these steps:

  • Using fine grained sandpaper smooth the trim panel surface where the adhesive material shall be applied -arrows-.
  • Using cleaning solvent - D 009 401 04- clean the trim panel surface on which the adhesive material will be applied -arrows -. Then rub edge of window dry using a lint-free cloth.
  • Apply glass/paint primer - D 009 200 02- on the adhesive surface of the trim panel -arrows-.

Sunroof

Note

Apply the primer evenly and in one step using a fully drenched felt.

  • Primer width approx. 20 mm
  • Apply primer centrally in relation to adhesive bead.
  • Flashing-off time, approx. 10 minutes.

Features of the adhesive bead and adhesive sealing material (PUR)

  1. Bead of glue
  2. Primer
  3. Trim panel for sliding/tilting sunroof.
    • Distance -a- = 8 mm
    • Dimension -b- = 12 mm
    • Dimension -c- = the area for the application of the adhesive sealing material (PUR) is different depending on the sliding/ tilting sunroof trim panel perforation.

General requirements for applying the adhesive bead

  • The sleeve -2- must rest flush.
  • Hold the gun permanently at right angles to the parts being treated.
  • The -Arrow- indicates the direction of travel.
  • The diameter of the adhesive bead -1- will depend on the width of the hole in the applicator and the speed of application.

  • Using the cartridge gun - SAT 5350- apply adhesive strip - D 190 MKD A3- on the surface intended for the adhesive material strip -arrows-.

Sunroof

Note Do not apply the adhesive material on both sides in the area marked with the height -a- = 100 mm.

fitting

WARNING

The trim panel must be fitted before 10 minutes elapse, as the adhesive properties of the adhesive sealing material (PUR) are reduced after that time.

Before inserting the trim panel it must be made sure that the drainage openings of the frame are free of any residue.

  • Apply the trim panel on the sliding/tilting sunroof frame.
  • Push the visor -2- with the pressure tool - T20098- downwards until it is certain that the seal -1- is in contact with the bodywork -arrow-.

Sunroof

Note The bodywork form allows the trim panel to be centred.

  • Check the installation position of the trim panel
  • Firmly fix the trim panel with masking tape.
    • Minimum curing period

 

  • In the top windscreen area -1- pull on the previously positioned rope, in order to bring the sealing lip -3- back into the correct position in relation to the sliding/tilting sunroof -2-.

WARNING

For safety reasons only use the following listed adhesive materials for the installation of the sliding/tilting sunroof trim panel.

This type of adhesive is specified due to its elasticity and does not cause any cracks in the paint on the trim panel after it has hardened.

You must NOT drive the vehicle until the minimum drying time has elapsed, as the vehicle is otherwise not safe to drive.
