8KO 915 181 C when googled comes up with "Battery Control Unit" and 4FO 907 468 F is "MMI Gateway", both relatively cheap to buy on ebay. CAN Bus is just(!) a type of communiucations network / protocol, like Ethernet, Modbus, Profibus etc. and in the case of Aud uses a fibre optic "cable" to pass data. A "gateway" is just that - a means of connecting to the network from a device - it changes the data into the correct form to be used on the CANbus.
