The clip did feel tight when i had a look but i guess slight movement over time would be enough, however, with it being secured to the chassis it shouldn't move at all because it has rubber sections of pipe built in which would absorb any movement. Anyway, i'm fairly convinced there is a strong case here against Landrover so i'll take my chances and get it booked in. The cost to repair the job is over £360! so it's worth a try.
