41 00... Installing A Cavity Acoustic Baffle (Expanded)
WARNING: This page is about a different car, the 2013 BMW 550i GT, 2012 BMW 550i GT, 2011 BMW 550i GT, and 2010 BMW 550i GT. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Carry over schematic representation to the relevant vehicle type.
The following repair represents the procedure for an already expanded cavity bulkhead.
The cavity bulkhead remains on the body in this instance.
Before these work steps, prepare the new part so that it is ready to install (adapting, cutting to size, applying welding primer etc.).
Clean contact surface (1) with cleaning agent R2.
Apply a bead (2) approx. 15 mm high of SEALANT D1 to contact surface (1).
In order to avoid run off of the sealant when bonding to a vertical surface, a thin coat of sealant on both sides of the surface may be necessary.
Fit, secure and weld up new part.
WARNING:
Ensure adequate ventilation over entire processing period.
