Hoorah, after three visits to the dealer they have finally traced and fixed the creaking noise.
Visit 1 - Loosen lower ball joint turn through 90 degrees and retorque - Didnt fix anything
Visit 2 - After consulting JLR both front struts replaced - Didnt fix anything - actually a bit worse
Visit 3 - Were going to change both lower wishbones but actually traced the fault to the anti roll bar rubber bushes which they apparently cleaned and lubricated with 'special' grease.
All sorted now, nice and quiet. They did say they had contacted JLR and notified them of the fault so it might not take so much time to trace the issues if you are unfortunate enough to have the same problem.
They hadn't had any others in with the same fault until later that same day when their demonstrator with 500 miles on the clock started doing the same thing and was next in line to be silenced after they finished mine
