BMW 7 Series: Repairing Clips For Roof Strip

The following instructions describe the permanent repair gluing of clips which were originally secured with Tpins.

The repair gluing at the same time protects the area of the torn-off T-pin permanently against corrosion.

1.0 Information on dangers/hazards

• Read and comply with the manufacturer's information on dangers/hazards prior to application.
• Avoid eye and skin contact. Wear solvent-resistant protective gloves.
• Do not inhale adhesive fumes. Apply in well ventilated rooms only.

1.0 Equipment

• ADHESIVE K4
• Static mixing tube
• ADHESIVE GUN
• CLEANING AGENT R1
• Adhesive tape for fixing

2.0 Preparing the surface

• Surface temperature of bonding surface and room temperature at least 18ºC.
• Cover area around bonding surface.
• Remove debris, flaked paint etc. from bonding surface with a brush. Use of compressed air prohibited!
• Clean bonding surface with cleaning agent R1.
• Let cleaned surface air dry for at least 2 minutes. Bonding surface must be completely dry.
• Do not contaminate bonding surfaces once they have been cleaned (sweat from hands, fingerprints, etc.).

3.0 Applying the adhesive

• Fill the hole (1) created by the torn-off T-pin with adhesive and spread over a length of approx. 4 cm (2) in the roof channel.

IMPORTANT: The hole must be completely filled or sealed with adhesive!

Fig. 60: Filling Roof Channel Hole Using Adhesive

Apply adhesive bead (1) to the underside of the clip.

In so doing, fill channel of clip with adhesive.

Fig. 61: Applying Adhesive Bead To Underside Of Clip

Move clip (1) into position and secure by hand.

If the adhesive is not already emerging evenly through the channel, apply additional adhesive from above.

Adhesive bead (2) must be below the clip height.

Fig. 62: Moving Clip

Secure clip with adhesive tape (1), approx. 150 mm long.

Apply adhesive tape in direction of travel.

4.0 Hardening period

• Adhesive tape can be removed after approx. 10 mins.
• Earliest possible load capability, e.g. fitting of roof strip, after 30 minutes.

Repairing Plastic Parts

1.0 General information

• Economic efficiency must always be checked prior to repair.
• Only the following painted components in the outer skin area are approved for repair:
  • Bumper trims (exception: E52)
  • Sill trims
  • Front side panels
  • Hardtop/roof
  • Convertible top compartment lid
  • Rear lid
• Prerequisite for professional repair:
  • Only minor deformations (without microcracks, usually visible in the paint)
  • Only minor damage, e.g. abrasions, cracks and holes up to 2.5 cm long
  • No damage (cracks) to the edge of the component!

CAUTION: The following are not approved for repair:

• Fuel tanks, reservoirs for liquids/fluids (e.g. windscreen washer unit, brake fluid, coolant expansion tank, etc.)
• Headlight mountings (pedestrian protection)

2.0 Shaping plastic parts

• Plastic parts can be reshaped using a hot-air blower.
• Microcracks can occur in the plastic if plastic parts are deformed. After the component is reshaped and then painted, the cracks may become visible again on the surface after a period of time.
• The component must be replaced if microcracks can be identified in the area of deformation.

3.0 Bonding plastic parts

IMPORTANT: Conform with safety precautions.

• A plastics repair box (sourcing reference: BMW Parts Service) is offered for cost-effective and time-value-compatible repairs.
• The plastics repair box contains the step-by-step instructions for repairing plastic parts.
