The following steps are shown on the left side of the vehicle and must be performed in the same way on the right side in the event of damage.

1. Mark separating points on A-pillar panel (1) and cut (area A₁ ).

   Do not make the cuts too deep.

   Otherwise the components below can be damaged and weakened.

   Transfer separating points from replacement part.

2. Expose MIG solder seam on A-pillar panel (1) and cut (area A₂ ).

   Position separating point (A₂ ) on weld seam.

3. Expose spot welds on A-pillar panel (1) and cut out (areas B₁ , B₂ , B ₃ and B₄ ).

12. Mark separating point on A-pillar reinforcement (3) and cut (area F₁ ).

    Do not cut too deeply.

    Otherwise the components below can be damaged and weakened.

    Dimensions: 

    a = approx. 10 mm

13. Expose MIG solder seams on A-pillar reinforcement (3) and cut (areas F₂ and F₃ ).

    Position separating points (F₂ and F₃ ) on weld seams.

14. Expose spot welds on A-pillar reinforcement (3) and cut out (areas G₁ , G₂ , G ₃ and G₄ ).
15. Drill out blind rivet on A-pillar reinforcement (3) (area I₁ ).

16. Heat A-pillar reinforcement (3) and A-pillar inner panel (4) in crosshatched areas.

    Cross-hatched areas are bonded with adhesive.

17. Remove A-pillar reinforcement (3).
18. Mark separating point on offset reinforcement and cut (area J₃ ).

    Do not cut too deeply.

    Otherwise the components below can be damaged and weakened.

    Dimensions: 

    c = approx. 60 mm

19. Mark separating points on A-pillar inner panel (4) and cut (area J₂ ).

    Do not make the cuts too deep.

    Otherwise the components below can be damaged and weakened.

    Dimensions: 

    d = approx. 120 mm

20. Expose spot welds on A-pillar inner panel (4) and cut out (areas K₁ , K₂ and K₃ ).

24. Sand down mating surfaces to bare metal in cross-hatched areas.

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

25. Remove grinding dust and drill chips.
26. Coat insides of spot weld flanges with zinc dust paint.

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

    Otherwise adhesion problems may occur.

    Observe pretreatment of bonding surfaces.
