This did work. I have a Laguna (UK X plate) with a front spoiler, removing the spoiler is easier than you think, some bolt head screws underneath and two near the weels. Pulling the cable is how I did it, but when you have the boot open you realise how easy it should have been. Persistance is the answer, it took me some time.
The drivers side (UK CAR) cable comes from the passengers side, the fault was the plasic holding the cable was broken.
Hope this helps someone!
