    My 540iT has convenient opening windows enabled. Unfortunately, to many times, while in my pocket, the key button is getting pressed and opening my windows/sunroof. This button push happens while I'm in a building. I come out hours later to see my car open to the elements. Luckily, it hasn't been raining or snowing. I'd like to disable this feature.

    The following document implies that this feature can be disabled.

    Can I disable this feature without special equipment? If not, what equipment is required?

    You'll need a dealer or well-equipped independent shop to do this.

    Somethimes this has nothing to do with your key fob. This problem has occurred on several different models and has been sometimes been traced to problems with the lock module or the body module. If you have it diabled and it still happens, you have other issues.

    Okay, the possibility of module problems didn't make my day.

    I also have a 325xit. The rear hatch randomly opens. I traced this to the electrical connection above the hatch. This connection is in a cavity which would be exposed to the environment except for a stick on adhesive membrane cover. Apparently mine leaks which wets the connection enough to act like the hatch button is pressed.

    I'll leave my keys on the table and see if the E39 windows still roll down. Better watch the weather too.

    Thanks for the heads up.

    Any luck fixing this problem? Was it a simple fix or did it turn out to be something else? :confused:
