Molded Foam Parts
Risk due to hazardous gases.
Sparks are created when welding and separating. If the sparks touch foamed areas within the body hazardous gases will be created.
-- Do not perform welding or separating with spark producing devices or tools in the near of foamed areas.

Molded Foam Parts - Sportback
On the Q4 Audi e-tron, various body cavities are equipped with molded foam parts.
The molded foam parts reduce the transfer of driving noises in the vehicle interior.
Molded foam pieces are installed in the body shell work and will get larger after priming in the paint drying oven at approximately 180 °C.
Since this temperature is not reached under workshop conditions, proceed as follows:
Prerequisite
- First a molded foam part and the Two-Part Filler Foam :D 506 KD1 A3 is required.
-- Remove any remaining foam from the vehicle.
-- Restore the paint structure.
-- If necessary, smooth over twice wet in wet using Primer :D 009 200 02 .
- Flash-off time approximately 10 minutes
-- Perform for example cutting, fitting, corrosion protection measures to prepare the metal part to be replaced so that it is ready for installation.
Molded Foam Part, Replacing
-- Secure the molded foam part on the vehicle.
-- Apply Two-Part Filler Foam :D 506 KD1 A3 on replacement part.
-- Secure the new part while gently pressing on it around the molded foam part until it makes contact and then weld it in.
The Two-Part Filler Foam :D 506 KD1 A3 hardens within 25 minutes.
When gas-shielded welding keep a minimum dimension of 15 mm to the Two-Part Filler Foam :D 506 KD1 A3 .
-- Seal the cavities in the repair area after painting the vehicle.
