I have a 2004 X5 3.0i that I bought in May. This is my first posting. This site rocks.....I've upgraded my NAV software with the great instructions provided. My car alarm has been going off randomly. The strange part is this only seems to happen when it's raining. It's doesn't take a massive downpour for this to occur and of course it only seems to happen after midnight. I've searched the forum and I don't believe it's the hood switch which seems to be the most popular reason for this type of problem. Anyone else come across this issue? Any suggestions?
