W164 Lights

[Aardvark]

I know that I am not alone in being a tad unhappy with the normal lights on the W164. What I would like to know is if it is easy fitting bi-xenons to my car. I am aware that I need to ensure all the electronics are in place but my car has airmatic so I assume it already has the self-levelling bits or the connections. In addition, I quite like the LED rear lights too which come together when ordered from factory but assume there is some coding required post fitting (I am aware there are non-merc parts with resistors to negate this but I only want to fit genuine parts).

Has anyone undertaken this on other models?

Mine is a ML320 CDI Sport Facelifted 09 Model.
