For now I uploaded the manual of how to install this kit in a A177 car. The guide should also be valid for W205:

I have chosen the installation of 2 handles (I only have one) and the tool did its thing without errors. However, it did not work. I tried using Xentry/Das to monitor the status of the handle in the keyless module and it is showing the change of status when the handle is touched inside (open) and outside(lock). The Chinise handle therefore works but there is a programming problem or a problem with key codea. Xentry indicates error because the handle in the passanger side is not present. I have searched the forum and found nothing specific, only some people trying to make additional keys to work with KG and some posts discussing that the key track should be 1 and 2 to work with keylessGO. if anyone knows where to program additional parameters in xentry please let me know.
