I have a 1992 525i, and recently the "open door" chime goes off when I accelerate from a stopping position...or when I go in reverse. Also, when I turn my key on the driver side to lock up, the driver side locks but the rest of the doors unlock. I realize I should just take it in as it sounds like a couple electrical issues. I was just wondering if anyone else has had either of these issues and if so, how/what do I do to fix it ??? Any help would be greatly appreciated. It is quite annoying to walk around and manually lock all the doors and hear the chime after a stoplight. Thanks!!!
