41 00... Opening Brazed Connections
WARNING: This page is about a different car, the 2011 BMW 750xi, 2011 BMW 750Lxi, 2010 BMW 750xi, and 2010 BMW 750Lxi. 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.
