Sound Proofing / Insulation: Service and Repair

41 14 021 Filling Bulkhead Crossmember With Foam

For acoustic insulation reasons insulating foam is applied to the finish-painted bodyshell in the bulkhead cross-member area.
A 2-component PU cavity foam is used.
Sourcing reference for cavity foam, refer to BMW Parts Department.
Observe safety and application instructions.







Remove seal plugs of cavities 1 to 3 and fill cavities with foam.
In so doing, insert spray pipe into bores and slowly pull out during the spraying operation.
To perform the operation, it may be necessary to lengthen the spray pipe.

IMPORTANT:
- Empty the can within 8 minutes.
- Follow manufacturer's safety instructions.
