This document is not applicable to cracks caused by external influence. This document only applies to vehicles with the option VW4 – Lightweight and Noise Insulated Glass. Technical Background The various types and causes of cracks in the lightweight exterior glass panes of the 911 are outlined below. Door glass: Cracks in the top corner (driver or passenger side) Figure 1 - Door glass: cracks in the top corner There are two main causes for this condition: -> The door glass is misaligned, which can cause contact between the door glass and the rear quarter glass, or -> Force applied to the glass (i.e., instead of the door sill) throughout the door closing process can bend the glass enough to cause contact with the rear quarter glass, despite a proper window alignment with no force applied. Updated lightweight door glass parts have been developed to address this complaint. Please see the Door glass: cracks in the top corner section of the Service Information for repair instructions.
