@jules, what usually happens is that one of the “C” clips break & the link just disconnects itself. That’s what happened to mine several years ago. I even found the broken bits lying in the chassis!

Once you know where it is, the actuator lever is easily checked (by feel) through the wheel arch, without removing the inner arch panel.

I've now installed a generic clip and time will tell if it holds - I was only trying clips for size with a view to installing it open-side-down but once it slipped on, it was going to be much more difficult to get back off, so I'm afraid it is going to stay upside down until it comes off on its own!

It was the 5mm e-clip from this set:
