Wind Noise and/or Water Leak Between Door Glass and Rear Quarter Window
If you receive customer reports in the above model vehicles regarding wind noise and/or water leak from the area between the door glass and the rear quarter window, this may occur if the gap between these windows is not parallel or even (Figure 1, arrows) when the windows are fully closed. The non-parallel or uneven gap can occur if either or both windows are adjusted too far rearward. To resolve, perform the below adjustments
Adjustment to Door Glass
1. Connect battery charger to maintain voltage of 12.5V.
2. Remove interior door trim panel, refer to WIS Document AR72.10-P-1000V.
3. Turn the height stops (Figure 2, circle only front adjuster shown) fully downwards.
4. Loosen front and rear bolts on window lifter with window lowered 2/3 of the way down (Figure 3 and 4, circles). Be careful not to shift the window and plastic wedge in the vertical direction.
5. Push window all the way forward to the stop.
6. Mark position of the window and then move the window 2 mm rearward.
7. With the door closed, check window for parallel gap and readjust if necessary. The gap must be parallel to the front section of the roof and 1 mm smaller in the area of the A-pillar (Figure 5, arrows).
8. Check the vertical dimension (protrusion of the side window relative to the mirror triangle 1 mm (Figures 6 and 7). If the dimension is not okay, loosen the front clamping jaws with the window up and adjust window.
9. Retighten front and rear bolts (Figures 3 and 4, circles) to 9 +/- 0.5 Nm.
10. Check the position of the front and rear guide rails in the vertical direction. The window overlaps the roof seal by 2 mm (Figure 8 arrow).
11. With the door and window closed, move height adjustment stops into position from inside the vehicle by pressing the quick release fitting (Figure 2, circle only front adjuster shown) upwards.
12. With the door and window closed, push height adjustment stops (Figure 2, circle - only front adjuster shown) upwards again from inside the car.
13. Reinstall interior door trim panel, refer to WIS Document AR72.10-P-1000V.
Adjustment to Rear Window
1. Open Vario Roof.
2. Detach trim at base of window.
3. Raise rear window using DAS actuations.
4. Check B-gap, should be 8.5 +1 mm (Figure 9).
5. If the B-gap is not okay, loosen bolts of clamping jaws (Figure 10, circles) and readjust rear window. Then retighten bolts (Figure 10, circles) to 4.5 +/- 0.5 Nm.
6. Check transition from door window to side window in Z-direction (Figure 11). The front edge of the door window must be set approximately 1 to 2 mm lower than the top edge of the side window.
7. The Z-direction setting is adjusted via the height stops (Figure 12, arrows); the direction of adjustment is indicated by the arrows. The rear side window must be lowered again using DAS actuations in order to obtain the maximum range of adjustment for the height stops. Then loosen the bolts for the height adjustment stops by turning the bolt clockwise (Figure 13, circle) and adjust the stop. After adjusting, retighten the bolts to 6 - 1 Nm.
8. Repeat steps 4 to 7 until the B-gap and Z-setting (transition) are okay.
9. Close Vario Roof with rear window lowered and check whether the window reaches the end position and that the B-gap is okay.
10. Reattach trim at base of side window and close roof.
11. Reinstall interior door trim panel.
12. Denormalize and renormalize windows using DAS.
13. Disconnect battery charger.
