My cabrio has a drain on the battery but the only fault the RAC could find is CANbus fault. I have managed to chase it down to a control unit fault but cannot identify which one, can anyone help? ???

I have now got fault codes but still no closer to finding the fault. Currently I have to disconnect the battery when I leave the car or it drains and sets the alarm off?
