41 00... EMC Screws

WARNING: This page is about a different car, the 2010 BMW 550i, 2009 BMW 550i, and 2008 BMW 550i. However, it is still accessible from the selected car via links, so may be relevant.

(EMC = Electro-Magnetic Compatibility)

Purpose:

EMC screws are used for repairs in the E60 (GRAV = reduced weight aluminum front end).
They assume the function of welded joints, which ensure transition to ground between the individual components.
The EMC screws ensure the operational reliability and safety of the electrical/electronic components following repairs!
Neither the punch rivets used as standard nor the blind rivets used in repairs ensure a transition to ground between the individual components!

Procedure:

Each welded joint which is opened must be replaced by at least 2 EMC screws.
Position the 2 screws on the flange on which the weld seam has been separated. In the event of partial replacement, position the screws in the area of the component overlap.
In the case of repairs using partial replacement, the number of EMC screws described in the repair instructions must be fitted.
Drill holes to a diameter of 4.2 mm and insert screws.
Seal EMC screws with PU sealing material (risk of corrosion).
