Corsa-B, Astra-G and Vectra-B models are now equipped with a new sunroof glass shell (4). In contrast to the old sunroof glass shell (2), which contained a metal frame (1), the new sunroof glass shell contains a PU outline (3) on the underside of the shell. By eliminating the metal frame, it was possible to improve the transition between vehicle roof and sunroof, thus eliminating wind noise. • Service The old Corsa-B and Vectra-B sunroof glass shells can be replaced, provided the new replacement part is from the same manufacturer (Webasto or Rockwell). |
