The removal was not easy, or more to the point is in a very awkward and hard to access place.
I do have a CD of the Jaguar Workshop Manual and likewise I searched looking for information and also found nothing was forthcoming. For the sake of urgency I have purchases from a dismantler who had been very helpful to me in identifying where/how to get to the Actuator . The only fault on the removed Actuator is that a very small piece of the end black push bar has broken off. I will at least have a spare that I can fiddle with if ever necessary, as it could well be possible, if one had the patience, to rebuild this end piece. At almost 72 years I am (unfortunately) not known for my patience with fiddly little things like this. However I am not chancing it for the sake of £25.
Many thanks for your help and continued interest in the outcome.
Best Wishes and Regards, John
