Reason for change
Complaint:
Wind deflector net loose.
Cause:
1. Profile rail (2) in PU channel in trim (1) maybe incorrectly installed (automatically ribbed by the supplier since 01/12).
2. PU channel in trim (1), gap too large.
PU channel in trim (1), material can expand in the heat, the gap becomes larger and the profile rail (2) can loosen due to the tension of the net.
3. The profile rail (2) may have ~barbs on one side only (should be on both sides).
Remedy:
Do not replace the wind deflector with net (3), but insert the profile rail (2) into the PU channel (1) by gluing the profile rail (2) on the left and right outside.
Use commercially available instant adhesive Loctite 495.
Clean Point: The profile rail is glued in series production (supplier) since 07/12.
