Left AF AND focus points problems !

Hi ! I suspected my D800 to have the "Left AF" disease, so I checked with the AF target I found on [url] http://julian.marmotandweasel.com/photos/AF_target.pdf[/url] !

I put the camera on tripod, in Manual, with the 14-24 at 24mm. 4 feet from the target, 1:250@ f/2.8, using an external flash ! I first autofocussed with the center AF point, shot, then rotated a bit the distance ring, moved the AF point to the extreme left, rotated the camera until the leftmost AF point was centered -to the center of the target-, autofocussed and shot again. I repeated the whole process, moving the AF point to the rightmost AF point !

Here's what I got (image from FastStone "Compare selected images" option):


...there's definitely a problem with the left AF point and slightly less with the right one, isn't it ?

Now, I checked the FOCUS POINT in ViewNX2, and here's what I saw:

How come ????? I DID center the left and right AF points on the exact same spot as I did for the center one, but it looks like both are totally off !!!

Any idea, answer, tips ?

Heeeeelp !
