Another (free) mod
I am playing it cheap for now, so here's another well known free upgrade to your F30. I discovered it recently on F30post and wanted to share for those of you who did not know about it either.
Your trunk may have become a bit 'lazy' when popping it up, especially with Comfort Access. It happened to me after I installed a rear spoiler (or for whatever other reason). It turns out that the springs tension can be easily increased. Just pull the trunk lining and you will notice that there are 3 different notches that can be used to attach the springs. I just moved mine from position #1 to position #3 and it took care of the issue.
