My 2006 A3SB has no alarm fitted. Yet, the little red diode on top of the front panel, near to the window flashes when the car is locked by the key. This little light is only mentioned in the manual, when talking about the alarm. Has any other member noticed this....is it normal? Also, in the manual it states that one push of the unlock button on the key opens only the driver's door and fuel flap. A second push opens all of the doors. However, in my case, one push of the button unlocks all of the doors. One push locks all doors. Is the dual-push facility turned on by VCDS?
