>> Just got it working by holding in the trunk button above the license plate for 10 or 15 seconds, then rapid taps of the same button.
>> I could hear the actuator pop back to the home position, and now works again!
Thanks, hingisfan, worked for me too. What a satisfying sound that was, when the actuator kicked on.
Now, what on earth made you come up with, 'Maybe I'll just push the button in and hold for 15 seconds, then rapidly press on and off after that.' ??
