My 01 300Wagon tailgate would lock when I pressed the central lock button, and would unlock likewise. When the car was unlocked, the tailgate opened without a key or other. The tailgate would not lock, unless I locked it, or I clicked "Lock" on the auto lock button on the door. HOWEVER, Since I got my BCM (Body Control Module) replaced last week, the tailgate locks EVERY TIME I shut it. I have tried setting the automatic lock/auto unlock feature as detailed in the owners' manual, but to no avail.
I called the dealer today, and after a pause he told me that my tailgate IS SUPPOSED TO LOCK everytime. That it was "malfunctioning" in the past.
I don't believe this. Please let me know if your tailgate locks automatically every time you shut it. For me, this is a real inconvenience, since I use my car's tailgate often in what Ido.
A thousand thanks, in advance.
