I just purchased an 05 last week and the next day I parked and locked. 5 minutes later someone was asking who owned the black BMW, the alarm was screaming! I unlocked and left it to diagnose later. It happened again at home and I did a search of solutions. Obviously the hood switch came up and I have unplugged it and no problems since. But....the little plastic button that pushes the plunger down on the hood had disintegrated. So, a new switch won't always solve the problem. I could fabricate something to activate it, but I am just leaving it alone since I can't remember the last time I heard of a hood being forced open to steal a 15+ year old car! I am posting this so people look at the whole scenario and don't just order a new switch and assume it will resolve the problem.
