Ive had the car stood for weeks at a time now and no problems inside the garage when the car has been left unlocked and unarmed. The car is finally on the road, so after a blast out at the wkend, i left the car on the drive overnight and locked obviously. I came out in the morning to find the battery completely flat!! Not even enuff to light the dash lights!!! Im sure this was happening before i changed the battery also, so it seems the alarm circuit is draining the power over a few hours when armed. Is there a common fault with these on A4's as i recall reading someone before having same issues with alarm??? Any idea what can be causing it? Also, is there any way of locking the car without arming the alarm as im sure using just the key in the lock will still arm the alarm??? Cheers.
