Hi, I am writing in English because I don't know German.
I also didn't have amiblight in my car, so I was looking for a solution in various forums, including foreign ones.
I couldn't find a solution so I decided to do it myself and it works! 
All you need is the original ambilight part e.g.

I had all the conectors what I needed. The only problem is the lack of holes for the led in dashboard and you need to drill it (it is not visible, it is under the covers). LED lights immediately after connecting (if you want settings in menu you have to use ddt4all).
First, check that you have a free black conector with three wires, it is on the left near the fuse box (two more are behind the screen).
Good luck !
