BMW X5: Opening Adhesive Bonds
1. Opening spot-weld bonds
- Set punch mark in center of weld spot. Set 8 mm dia. weld spot drill bit
on punch mark and drill
through top metal sheet.
Or open weld spot with Vario Drill spot welding cutter (refer to WORKSHOP EQUIPMENT & PLANNING CD, Chapter 7).
NOTE: Because the weld spots may have surface-hardened, grind them if necessary with an angle grinder and paper grinding disk.
- Heat connecting flange with a hot air blower.
CAUTION: Extract vapors and gases.
- Release connection flange with chisel.
- Grind off residual adhesive from connecting flange.
2. Opening adhesive bonds on aluminum parts
- Remove punch rivets or blind rivets.
- Roughly cut out damaged component. The component can be peeled with the aid of pliers. If necessary, heat bonding flange with hot air blower.
CAUTION: Heat only the damaged component with a hot air blower.
- Extract vapors and gases.
- Grind off residual adhesive from connecting flange.
CAUTION: Wear a grinding dust mask.
- If engine carrier part replacement on the GRAV is carried out repeatedly, cut the damaged part at the existing cutting line. Heat bonding flanges with a hot air blower. Peel off remnants of expander elements with pliers.
3. Opening adhesive bonds on carbon-fibre-reinforced plastic parts
Procedure is described in detailed in the relevant repair instructions.
OPENING WELD JOINTS
1. Opening weld spots (resistance pressure spot welding):
- Set punch mark in center of weld spot. Set 8 mm dia. weld spot drill bit
on punch mark and drill
through top metal sheet.
Or open weld spot with Vario Drill spot welding cutter (refer to WORKSHOP EQUIPMENT & PLANNING CD, Chapter 7).
NOTE: Because the weld spots may have surface-hardened, grind them if necessary with an angle grinder and paper grinding disk.
2. Opening laser weld seams:
- Place angle grinder with grinding disk on laser weld seam and grind through top metal sheet. Be careful not to cut through and damage sheet metal underneath.

POSITION OF SHAPED PARTS FOR CAVITY ACOUSTIC BAFFLE
Cavity sealing is carried out in specific body areas in order to reduce internal noise and to reduce condensate.
To do this, shaped parts are inserted in the cavities. These shaped parts adapt themselves optimally due to heating of the body to approx. 180ºC by expansion to the shape of the cavities.
Because it is not possible to heat the body to this extent for a body repair, a different procedure has been specified for this situation.
