Went to the dealership today after texting a tech about my spoiler issues.
Issue can be found here http://www.e90post.com/forums/showthread.php?t=729376
My spoiler would have flown off my car in a matter of days had I not retaped it. It came off in one try very easily he said with almost no force.
They used 3M and another stronger adhesive so it had double the strength. Used painters tape to hold it down. I kept getting weird looks driving home haha. Painters tape will come off Monday. No washing my car until after then.
