41 00... Opening Brazed Joints
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.
The "Bonding and Riveting" repair method involves replacing the watertight brazed joint with adhesive.
This gives rise to a new procedure for opening brazed joints.
Grind brazed seam with a belt grinder. This keeps the influence of heat in the area around the brazed seam as small as possible.
IMPORTANT:
Never use a gas flame.
All traces of brazing solder do not have to be removed.
Do not grind body panels thin.
