clips snapped, common problem ive had to fix loads, i tried superglue and it worked for a bit but then came off again, what i do now is...
you will see at the back of the gaitor at the bottom plastic bit (bit closest to back of the car) there is a little rectangle plastic bit sticking down where the clip has snapped off, get a screw and screw it in there to act as a clip and it will sit back in fine, only problem is i cant get mine back out now lol
