L322 Range Rover HSE 05 (55 plate) - Transferbox Neutral Issue

Hi - this is my first post so hopefully I am providing the correct information for someone to help/advise??:

My RR intermitently display flashes up with 'Transfer Box Neutral' and bleeps (the amount of flashes/bleeps can be a single bleep to up to 30+ one after the other) this can be coupled with or independant of the Hi-Lo green icon appearing on the dash also (this is sometimes solid or flashing).

I have had the RR plugged in at my local Main Dealer only to be informed that their machine can only read certain defaults, and due to the age not mine but it has diagnosed up to a code: 0x2062 - TCCM but cannot go any further! Land Rover have advised to go to another Main Dealer who they say may have another machine which would be able to invesitage further - i am keen to try to avoid this to avoid the potential of the same happening.

Any assistance/experience of this would be much appreciated. If you need any further information in order to advise I would be happy to provide this.

The transferbox shift motor has a switch pack on the rear to tell it which ratio it is in - this has been known to crack and fail.....that would be my first point of investigation....

Google will return details of how to check it for function i am sure.....but is probably the first port of call.
