Why if i buy full coplete diff, with haldex and haldex controller? Diff body have the same size.

I think I read about this before. Tried to find the thread on it.
The controller is different. They do not speak the same language (protocol)

If I do not remember wrong, the thread was replayed from a Haldex tech guy.
Sorry I could not find this.

Maybe other here can give you a better answere?
