I've connected to the convenience bus (green wire) right by my canbus gateway in my Polo 6R and I do see all the messages on the bus fly past so that's working well and all.
I've figured out the ID for the steering wheel buttons and I am able to replay it and my radio indeed does respond to it, however... When I send for example a message for the wipers my car does not respond to it at all. Blinkers, headlights, door locks, etc... Nothing else will respond.
I'm a bit baffled now because I was connected to the bus right behind my radio before but moving down the tree to right before my canbus gateway it still doesn't seem to work.
Has anyone else worked on a VW MK5 model that could give me some insight into my problems and how to make it work?
