Re: 156 boot strut
Are the existing struts still holding the boot lid up ok? The "pop" when you undo the boot lid is the tension in the lid stops releasing, not the struts.
Sounds like your lock/striker pin may be slightly misaligned. Open your boot and have a look down at where the striker pin is (the pin that the lock snaps round when shut). It may have been moved by a particularly energetic slam of the trunk, esp. if there was something in the way at the time!
