Repair in area of sound insulation, door

WARNING: This page is about a different variant/trim than selected.

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 )

The sound insulation must be bonded watertight below the door lock:

Flat bonding surface required all round
No bonding in event of moisture (e.g. condensation, etc.)
Bonding area must not show any traces of adhesion-reducing residues (e.g. separating agents, greases, oils, paraffins, plastisols, cavity wax, polishing dust residues, etc.)
Remove the protective film directly before joining (under no circumstances remove earlier, since the butyl, because of its stickiness, will very quickly pick up adhesion reducing dirt contaminants)
The sound insulation must be attached with positional accuracy to the inner door panel, because it is no longer possible to change the position without damaging the butyl bead
With repainted areas, the maximum permitted temperature of 90°C may not be exceeded in the area of the sound insulation. Otherwise, the sound insulation must be removed (and replaced, if necessary).
