So, you have a 2007 and that is known as a pre-facelift or pre-LCI model. As someone mentioned before, the LCI or facelift model started production as a model year 2011 vehicle in August 2010. After March 2011 there was a lighting upgrade, specifically the Halogen corona (angel) eyes were changed to LED.

While any headlight from any E70 will physically fit or be made to fit relatively easily, there will be considerable modifications needed to fit an LCI headlight to a non-LCI vehicle and have it work 100% as intended. You should look for a headlight from a MY2007, 2008, 2009 or 2010 vehicle equipped with Xenon headlights.
