Hey guys. I had a question about retrofitting comfort access to my 528i. If I am able to get parts from a F30 328i, can I use any of those parts in the retrofit and what would I need to replace? I'm sorry if this is a silly question but I'm new to this whole bmw thing and this is the first car I'm ever even considering doing these things let alone doing them. :

Thanks so much!
