Mein Auto: 328i
Trunk opens while driving

2007 328i. Trunk just started opening spontaneously while driving yesterday. I pulled over several times to close the trunk. Started down the road again and the the trunk open warning flashed and sure enough the trunk lid is open. Anyone else experience this?. I searched the forum and web and have not found any reference to this issue.

You answered your question before finishing your post. However, gotta wonder: Do you hear the trunk latch whirr as it locks down the latch, on closing - normal op? Open normal?

I had the same problem on an 08 750 replaced the micro switch assembly for approx. $75. can you lock the switch off by the valet switch in the console or glove box. This cured mine until I replaced the switch.

Good advice. Micro switches are the first thing to look at, though part cost may be $0.75 to BMW....

If you have comfort access, and the key in your pocket ... could something else in your pocket be pressing the trunk release button?

Are you sure you don't have a Volkswagen ? lol... It's a kind of Volks issue... Seriously, thanks Esiedsma for the advice, I have a 328 2007 too. So I will know where to check if this problem happens.
