For some reason, the 2/3 section of my rear seat has stopped folding. One day it was fine and the next it stopped. I originally thought the inside of the plastic handle was rounding as it seems to part release, but not far enough to release from the catch. I bought a new handle but it has made no difference, I tried a pair of mole grips and clamped onto the metal bar but in my *cough* wisdom, managed to snap the top section off. So, I'm now left with a seat I cannot fold down because the mechanism is broken, but because of the design, I can't access the mechanism until the seat is folded down. A pic of the top section so you know what I'm talking about... Anyone have any ideas?
