What it covers
A service bulletin tells BMW technicians how to diagnose or fix a known issue. It is not a recall: a repair under a bulletin is normally paid by the owner unless the car is still under warranty or a warranty extension applies.
STREAKS ON FRONT SIDE WINDOWS: Streak marks are visible, most commonly on the upper rear corner of the front side window. The marks can be present anywhere on the rearmost edge of either front window.
