41 00... Installing Cavity Sealing (Expanded)

WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2016 BMW 435i xDrive, 2016 BMW 435i, 2016 BMW 428i xDrive, 2016 BMW 428i, and 2015 BMW 435i xDrive. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Carry over schematic diagram to the relevant vehicle type.

The following repair represents the procedure for an already expanded cavity acoustic baffle.

The cavity acoustic baffle 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 D2  to contact surface (1).

If necessary apply sealant D2 somewhat thinner on each side, to prevent the sealant from running.

Fit, secure and weld up new part.
