41 00... INSTALLING CAVITY SEALING (EXPANDED) (330i xDrive Wagon, 328d xDrive Wagon, 330i GT xDrive, 340i GT xDrive)
WARNING: This page does not describe the selected car, but rather 11 other vehicles, including the 2019 BMW 340i GT xDrive, 2019 BMW 330i xDrive, 2019 BMW 330i GT xDrive, 2018 BMW 340i GT xDrive, and 2018 BMW 330i 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.
WARNING:
Ensure adequate ventilation over entire processing period.
