I have a convert with no comfort access or at least I don't think!
I can pull the roof down by holdin unlock but if I hold lock it simply locks the car.
I'd also want my mirrors folding in so I want exactly the same features as your video.
it's an 07 320i and it had some safety changes done in may. Dunno what software or anything is on there.
This is the first time ive looked at coding but I'm eager to buy the necessary tools and give it a crack!
