Reason for this Service Bulletin
Aston Martin has found that some DB11 vehicles have had water leaks through the windscreen. The primary cause of the
problem is that some of the rivets in the body structure were not installed flush. This can cause a failure in the sealant
bond for the windscreen.
When the windscreen seal has this defect, water can leak on to the centre stack assembly and/or on to the VIN plate
(refer to Figure 1). If there is an indication of a leak, do the workshop procedure that follows.

Figure 1

Workshop Procedure
This workshop procedure has two parts. If the windscreen continues to leak when Part A is complete, you must do
Part B.
Part A – Seal the windscreen
Part B – Replace the windscreen
