I have a 2009 series 1 convertible. Around 3 months ago my key started to only work after I pressed the button a few times to unlock or lock, then it got worse, then about 6weeks ago the controls on the drivers door would not work. Then a week ago all of the electrics inside the car stopped working, the lights, all the windows (2 back windows are down and I can’t get them up), the roof controls don’t work as well as the indicators. Warning lights do work. I was advised to disconnect the battery for 20 minutes which I did and once reconnected I’ve got some warning lights showing that were not there before. Anyone have any idea what this could be? When the voltage on the battery was taken it was on the 3rd light (out of 6) could the problem be the battery?
thanks
