The next steps are shown on the left side of the vehicle. In case of damage on the right side of the vehicle, these steps must be performed analogously.

The superordinate service document as well as the safety information in the service document must be observed.

1. Mark separating points on A-pillar reinforcement (1) and cut (areas A and B).

   Do not make the cuts too deep.

   Otherwise the components below can be damaged and weakened.

   

   Dimensions:

   a = approx. 100 mm

   b approx. 60 mm

2. Expose spot welds at A-pillar reinforcement (1) and cut off (areas C₁ , C₂ , C₃ ).

   

   Joint spot welds on panels that are one behind the other must be cut out through two panel thicknesses.

4. Expose spot welds at A-pillar reinforcement (1) and cut off (area E).
5. Heat A-pillar reinforcement (1) in cross-hatched areas (areas F₁ , F₂ , F₃ ).

   

   Cross-hatched areas are bonded with adhesive.

6. Remove A-pillar reinforcement (1).

7. Mark separating points at A-pillar inner section (2) and cut (areas J and I).

   Do not make the cuts too deep.

   Otherwise the components below can be damaged and weakened.

   

   Dimensions:

   j = approx. 60 mm

   i = approx. 60 mm

8. Expose spot welds at A-pillar inner section (2) and cut off (areas K₁ , K₂ , K₃ , K₄ , K₅ ).

11. Grind mating surfaces down to bare metal in cross-hatched areas.

    

    Sand down spot weld flanges to bare metal on both sides.

12. Remove grinding dust and drill chips.
13. Apply zinc dust paint to insides of spot weld flanges onto connecting flanges that are no longer accessible after installing side roof paneling

    Do not coat bonding surfaces with zinc dust paint (areas M₁ , M₂ ).

    Otherwise adhesion problems can occur.

    

    Observe pretreatment of bonding surfaces.
