| Repair in the event of damaged sound insulation or leakage |
- Cut the butyl rope between the sound insulation and the inner door panel with a sharp knife
- After the repair is finished, position a new butyl rope Ø 3 mm directly on the original adhesive bead
- Heat the butyl bead with a standard hot air blower until the butyl rope strings when touched slightly. Do not damage the sound insulation in the process
- Press on with special tool 51 0 300
. Perform this work extremely carefully because the increased amount of adhesive requires contact pressure of ≥ 20 N/cm2
(compared to firm thumb pressure ~ 30 N/cm2
)
- Visually check the adhesive bead and its compression (no capillaries or broken adhesive bead permitted)
- In the cases mentioned, the complete sound insulation must be replaced. After removing the sound insulation, removal all butyl remnants from the inner door panel. Apply 6 mm Ø butyl rope to new sound insulation
- Press on with special tool 51 0 300
. Contact pressure ≥ 20 N/cm2
(compare to firm thumb pressure ~ 30 N/cm2
)
