Vario Roof Inoperative / End Position of Side Flaps Not Reached
If you receive customer reports in the above model vehicles with the below conditions, this may be caused by the mounting plate on the drive unit of side
flap being bent or broken (Figure 1).
-
Vario roof inoperative
-
End position of side flap is not reached
-
Noises in the area of the side flaps
To resolve, replace both mounting plates of the side flap drive units on both sides of the vehicle as follows:
1. Open trunk lid and cover/protect rear fenders to protect against damage.
2. Turn adjusting nuts on Bowden cable of side flap drive unit on both side flaps, three turns counterclockwise (Figure 2, 1). This eliminates the
preload at the side flaps.
3. Unplug electrical connector from microswitch.
4. Detach left and right side flaps from trunk lid, remove nuts (Figure 2, 2).
5. Unscrew torx bolts at rear of mounting plate (Figure 3).
