Document A4 8D, production date up to 10/1999, dents on the D-pillar (Solution)

Dents or depressions on the outer surface of the D-pillar.

Incorrectly set mixing parameters for the insulation foam in the D-pillar result in shrinkage of the insulation foam. The insulation foam, which is attached to the outer skin of the D-pillar, is integrated into the structure.
