My trunk unlocks and locks by itself - x5
About a week ago my trunk on my 2002 X5 3.0i started to unlock by itself while i was driving or idling. I would stop the SUV and slam it shut again and a few seconds or minutes later it would unlock by itself again. Never fully opening because it semi re-locks. What can be the problem or how to fix it? My battery is practically new and I am 99% sure its not the key fob. HELP!!!
