Sound Proofing / Insulation: Description and Operation

Body Foam Insulation

The 1998 Beetle has various body cavities that are foam treated.

Foam locations are described in the individual repair instructions.

Foam Insulation is a pre-formed synthetic material that reduces noise transfer to the interior.

The parts catalog shows insulation on illustration 863-20.

The pre-formed foam parts are installed during body assembly, they expand during drying time in the paint shop oven at approx.180° C (388° F) after priming.

As these temperatures cannot be achieved under normal workshop conditions, proceed as follows:

Prerequisites

• Before continuing with this procedure, ensure the replacement part is correctly prepared.

• Remove excess foam material.

• Repaint, apply two coats (wet on wet) of glass/paint primer D009 200 02 if necessary, flash-off time - approx.10 min.

Replacing insulation

- Apply sealing cord AKD 497 010 04 R10 around circumference of insulation.

- Install insulation.

- Attach new part (e.g. A pillar) and position new part by pressing gently in insulation area and weld in place.

• Do not SG weld 15 mm (0.59 in.) either side of insulation.

- Re-under coat repaired area after painting vehicle, as required.
