How can I tell what type of window I have?

[rebouch1]

I have a 2005 X5 4.4i. Someone decided that they liked my computer bag sitting behind my drivers seat the other night and broke my left rear window. Now I need to order a replacement window for my left rear door but I'm not sure what color it is. I noticed that on RealOEM there are two colors listed. Is there a way that you can tell from the VIN or other code which color window I have? In RealOEM there is one that is listed as "Side window, green, door, rear left" (51348402571) and the other is "Side window, black, door rear left" (51348249927). When I look at the window it appears that there is a possible tint of green, but it is very hard to discern...it almost looks black. The right rear window has the following markings (I can't read the left since the crook shattered it):
Saint Gorbain, SEKURIT, 43R-004553, DOT 615M40VGAS3, E000214.
Does anyone have an any idea on how I can tell which to order? Thanks for the help.

Of course it does not help that I'm color blind, but my wife thinks she sees a slight tint of green in the window.

I was able to use the different posts on how to switch out a regulator (thanks to the forum) and I was able to take the door apart and clean up all the glass fragments...it is now waiting for a new window...

Green is the normal glass, Black is the Sun Protection Glass (B-pillars rearwards). If you don't have SPG then it's the Green one.

Thank you for the response X5Sport. For clarification. I do notice that the windows rear of the B pillar are darker than the front windows...would that be the SPG or do they do that for the normal glass as well?

If they're darker then that sounds like SPG to me. Mine have a black tint from the 'B' pillar rearwards including the hatch.

I think the green ones are those where the glass is the same light tint all round - that being the default (in the UK anyway) - but most owners I know have the black tinted SP glass.

It's the same on both the E53 and E71
