i just replace my trunk springs, and the same problem i had before has not gone away, which is the trunk does not want to stay up. Does anybody know what this could be, or could i have put the right spring where the left one goes and vice versa, because the look the same. Also what is the bmw part number for the springs because maybe i bought the wrong ones, as i found out that there is a spring if your trunk has a spoiler or doesnt have one.
