Wondering if anyone knows or come across doorlock unlocking twice when unlocking the car? And its only doing it on the rear driver side door. I bought this car not too long ago and the acuator on the driver door wasnt working so i replaced all 4 door acuator motor. Now all the door will lock and unlock but only rear driver side will unlock twice...

 

My next guess would be the door ecu. They're cheap and easy to replace. I'm not sure how likely it is to be the culprit, just throwing it out there.
