Installation recommendation

Before installation:

• Confirm the vehicle model and production specification

• Compare the BMW part number and rubber profile with the original seal
• Carefully inspect the complete NOS seal after opening the packaging
• Allow the rubber to rest unfolded in a warm environment
• Check for cracks, hardened sections, shrinkage or permanent deformation
• Clean the glass edge and body mounting surface
• Inspect the window opening for rust or previous repairs
• Test-fit the seal before final installation
