41 00... Position Of Shaped Parts For Cavity Bulkhead

WARNING: This page is about a different car, the 2010 BMW M5, 2009 BMW M5, 2008 BMW M5, 2007 BMW M5, and 2006 BMW M5. However, it is still accessible from the selected car via links, so may be relevant.

Cavity sealing is carried out in specific body areas in order to reduce internal noise and to reduce condensate. To do this, shaped parts are inserted in the cavities. These shaped parts adapt themselves optimally due to heating of the body to approx. 180°C by expansion to the shape of the cavities.

Because it is not possible to heat the body to this extent for a body repair, a different procedure has been specified for this situation. Refer to:

INSTALLING A CAVITY ACOUSTIC BAFFLE (EXPANDED)
INSTALLING CAVITY SEALING (NOT EXPANDED)
INSTALLING A CAVITY SEALING WITH 2-COMPONENT PU CAVITY FOAM
