Anybody know what this is? DB11 weird white mark on window
Discussion
Unfortunately your camera's auto-focus has picked up on the road surface and not he defect, so you can't see it clearly if you zoom in. I've never seen anything like that in all my years associated with the auto industry; but I could have led a sheltered life
I've forgotten the specs of a lot of the DB11 now, so I'm not sure if laminated side glass was an option or standard fit. You can check by dropping the side glass about half-way then looking at the top edge - laminated often has a "double bubble" appearance, whereas toughened is one smooth ground curve.
Another test you can do is to put something against the glass then get close and look at the point of contact closely - does there appear to be a gap between the point of contact and the defect? Now do the same from the other side of the glass - again is there an apparent gap between the contact point and the defect? A torch can help. If you see an apparent gap when viewing from both sides then it implies the defect is within the glass so could be a delamination or water getting into the interlayer film; if there's no apparent gap on one side when you look at it then the defect is at or on the surface of the glass.
One other thought - it doesn't have an aftermarket tint film applied does it? I can see it's a RHD car and such things can be more common in markets like the US. You can check for this by, once more, dropping the glass and looking carefully at the very edge of the glass panel - the tint film should finish slightly inboard of the edge of the glass. It will also be on the inside.

Write to AML head office and request they replace what should not be faulty. Surely there would be a standard expectation of life span for a laminated side glass. Shake the tree a bit as if it happened to you it may happen to many other cars as usually these things are not a one off.
Failing that I am sure there would be a second hand one somewhere.
