2.) Rubber buffers must be positioned directly above the mechanism eye. (Aim: trim must be kept away from
mechanism by rubber buffers)
3.) Cross-sectional view: position of buffer between trim and mechanism

Procedure:
Remove the front glass panel according to the Workshop Manual.
Remove the water guiding washer using a diagonal cutter or cutter knife.
Ensure that you do not scratch surrounding metal components. You may wish to mask off the
surrounding areas first.
Remove plastic swarf from guide rails afterwards using a vacuum cleaner.
The plastic must be cut back so that it does not protrude from the silver pivot pin; it should be flush with the pivot
pin.
As this area is hidden by the glass panel later, it is not necessary to perform cosmetic work on it.
Fit the front glass panel according to the Workshop Manual and adjust it correctly.
Modification no. 4
Attach rubber buffers (glass panel with “long” PU trim).
Clean glass panel on the inside (see Figure 34). The glass panel has been removed here for greater clarity. When
working on the vehicle, the glass panel is not removed.
Clean front right/left glass panel PU trim (inside) using cleaning solution D 009 401 04.
