Seal Between Top of A-Pillar and Roof Panel Collapsed
If you receive customer reports in the above model vehicles that the seal between the top of the A-pillar and the roof panel has collapsed (Figure 1, Pos. 1), this may be due to insufficient return force within the seal. It is not necessary to replace the seal. Special clips have been developed to resolve this issue.
1. Move Vario Roof to assembly position, refer to WIS document AR77.50-P-3000-01V.
2. Remove hose glued into windshield frame seal and Vario Roof front section.
3. Insert long clip into windshield frame seal. Insert clip along channel (Figure 1, Pos. 5) and observe insertion depth of 30 mm (Figure 1, Pos. 8 and A) to insure the water drain hole (Figure 1, Pos. 7) is not blocked.
4. Insert short clip into Vario Roof front section seal (Figure 1, Pos. 3) approximately 3 mm deeper than the front edge of the seal.
5. Remove support and close Vario Roof, refer to WIS document AR77.50-P-3000-01V.
6. With the door windows open, align the junction between the seals. If necessary, use a hot air blower to warm the seals as an aid to aligning the seals.
7. Close the door windows and check that the windows enter the roof seals correctly, correct window adjustment if necessary referring to WIS document AR72.10-P-1950V.
8. Perform rain test to check for leaks.
