Mine is a 20mm dia round disc that comes out of the front bumper below the inner bulb of the right headlight cluster. An eye on a stalk (to be found in the plastic tray in the spare wheel) screws into the resulting hole.
A slim istrument such as a knife is handy for removing said disc but watch the paint!
If it is not there I cant help you. I only know as mine had to be towed a while ago
