THIS REPAIR IS MOBILE FRIENDLY

MODEL
E-Series
F74

Model Description
2 Series Gran Coupe

Production Date
January 9, 2025 – January 15, 2025

SITUATION
A crack may have formed in the upper left
corner of the trunk opening (circled in red),
where the quarter panel contacts the left
lower corner of the rear window and trunk
water channel.

Illustration of the inward-facing metal shows
the general location of the possible crack,
though the area to be checked in the
Procedure is on the “back side”/outwardfacing surface.

The PVC seam sealant applied to the water
channel may not sufficiently seal the channel
in the presence of the crack, resulting in a
small water leak into the trunks interior.

The green dots represent the location of
spot welds.
