Is there any signal when you guys locking your x5? For example, the turning indicator flashes once when locking the door and flashes twice when unlocking the door.

My X5 does not flash when locking the door but flashes twice when unlocking the door. Is it normal, if not, can someone tell me how to make it flash once when locking the door?
