The return spring on my Octavia Turbo has broken and I was trying to sus have the latch worked. Weird set up. The bonnet latch lock lever which is under tension of the spring is released by the outside sleeve of the cable. Not by the internal wire of the release cable. The internal wire remains stationary as it is secured to the latch mechanism by way of a profile on the end of the wire and a plastic grommet. The plastic grommet fits into the square cut-out (bottom right) and allows the exterior sleeve to move through it and thus releasing the lock lever. Al I need is to find a replacement spring!
