I still doubt the BC1 is blown but if you have a multi meter then unplug the connection and test if the voltage is there. If not id get BMW to check the BC1 for fault codes and see if its even activating the outputs. Each output is seperately controlled from each other as I proved at the weekend. If you dont want to pay the costs of BMW then grab me if you are coming to top gear and i'll plug my laptop in and you can manually activate it yourself.

Best tool I ever got my hands on for the MINI
