2.2 Larger defects (mechanical damage and larger separations of seal)
WARNING: This page is about a different car, the 2013 BMW X5 M, 2012 BMW X5 M, 2011 BMW X5 M, and 2010 BMW X5 M. However, it is still accessible from the selected car via links, so may be relevant.
- Complete replacement of rubber seal necessary
- Peeling off damaged rubber seal:
- Pull off rubber seal slowly at an angle up to 20° under uniformly strong tension.NOTE: Make sure the connection between adhesive tape and gasket is retained.
If the connection between adhesive tape and seal is detached: Carefully and slowly detach adhesive tape at an angle of 20° from roof aperture or lid.
When existing gaskets are being peeled off with a hot air blower: Do not damage paintwork.
Do not detach rubber-adhesive tape connection if at all possible.
- Pull off rubber seal slowly at an angle up to 20° under uniformly strong tension.
- Cleaning bonding surface:
- Degrease bonded area with adhesive remover and remove other residues.NOTE: Use necessary cotton- or fluff-free paper towel once only.
When using solvent: expose repair area to air for at least 2 minutes.
- Degrease bonded area with adhesive remover and remove other residues.
- Detaching protective film from bonding surface:
- Detach protective film from rubber seal in sections.
Attention:
Once the protective film has been removed, do not under any circumstances touch the exposed bonding surface.
- Detach protective film from rubber seal in sections.
- Applying rubber seal:
- Apply rubber seal on roof aperture edge beginning at rear center. Use upper lip as reference edge. Press on gasket continuously by hand. Carefully unwrap seal at radii without tension and press down (critical area).NOTE: If positioned incorrectly, the gasket can still be pulled off, repositioned and pressed on again.
- Apply rubber seal on roof aperture edge beginning at rear center. Use upper lip as reference edge. Press on gasket continuously by hand. Carefully unwrap seal at radii without tension and press down (critical area).
- Establishing sealing joint:
- Mark contact point at joint by pressing down loose end on seal of already bonded end. Then cut and press down loose end at same height.NOTE: Small areas of gasket can remain stuck to adhesive tape of loose end.
- Mark contact point at joint by pressing down loose end on seal of already bonded end. Then cut and press down loose end at same height.
- Pressing on gasket:
- Press on seal using a roller
- Adhesive tape width up to 5 mm Contact pressure approx. 5 N
- Adhesive tape width up to 10 mm Contact pressure approx. 10 N
Slide/tilt sunroof gasket only:
- Press against seal strongly with a roller. Contact pressure approx. 70 N.
Seal only, slide/tilt sunroofE36:
- Contact pressure approx. 30 N.
- Remove the tear-off lip from the rear and side near the narrower flange.NOTE: Firm thumb pressure has approx. 35 N/cm2
