I too have had recurrent alarm problems on my 2009 TF. First, the alarm would sound on starting the car, and occasionally when it was parked. This appeared to be because of a largely dead battery, as the problem went away after a battery change even though (due to a knee operation) the car was not used for the next 4 weeks or so. Now the problem repeats itself, perhaps because the car is not getting much use. The fuse is now pulled, but I plan to use the car tomorrow. I assume the alarm will sound as soon as I insert the fuse, so have armed myself with suitable ear defenders. Does anyone know what the best course of action then is to get the alarm to stop, or will it stop by itself?
