41 00... Position Of Shaped Parts For Cavity Acoustic Baffle
WARNING: This page is about a different car, the 2013 BMW Z4, 2012 BMW Z4, 2011 BMW Z4, 2010 BMW Z4, and 2009 BMW Z4. 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 See 4100... INSTALLING A CAVITY ACOUSTIC BAFFLE (EXPANDED) or 4100... INSTALLING A CAVITY ACOUSTIC BAFFLE (NOT EXPANDED) has been specified for this situation.
