Because I haven't had the opportunity to try FL1 when it was new, it would be interesting to learn how the rear door operated when the gas strut was new? When I bought mine 280 tkm driven 2004 FL1 the strut was extremely stiff. I have lubricated it often and now it's better but still I have to push the rear door open. It also stays open thanks to the strut but should it actually push the door open itself? Have you replaced the original strut?
