Trunk / Boot unlocks itself on my x5
Hi I have the same problem.
I have a BMW X5 2002, for no reason my boot just unlocks, i think it usually happens when idling or when I stop. I only use the spare key manually as my car needs a new electronic keyfob. The boot being opened has caused the boot lights to stay on. Hence, my battery going flat while lights on for 4 days. My battery is fully charged now, and the boot problem is still happening. So I believe it's not my battery nor my key causing this problem. But I could be wrong. does anyone have any ideas?
