Over the past few weeks my alarm has been going off after i have used the remote keypad to lock it, also my rear wiper has stopped working and on the dashboard display keeps saying the boot is open (when it is definatley shut). Due to this my battery went flat over night as the courtesy light stayed on, Mr AA came to jump the car and said it is a common fault with a3's as there is one unit in the boot that operates all of the above. Has anyone else come across these problems as it is driving me nuts.
