i'm in and out of my boot all the time and had my springs replaced just before warrenty ran out i've noticed this morning that the part of the hinge that the springs sit in has snapped away from the rest of the hinge.
it looks like i will have to take parcel shelf out to get boot lid hinge out to get it replaced or welded.
some of you may have the same problem as mine used to lift now just pops open (sport with spoiler)
