So.... Update.
I have my car back, after much fighting words and threats of buy-backs and quoting our Lemon Laws... List of items replaced:
Headunit
Engine / Gearbox Mounts
Aircon Compressor
Plastic Covers
Boot Shocks
Control Arms
Exhaust Heat Shields
Flushed Gearbox Oil / Replaced
Adaptions
While the car was there I had them replace the Transfer Case Oil (used Ravenol Xdrive approved Fully Synthetic), which they covered the labour for as a courtesy. All the faults are recorded on the cars history and I have copies of all the job cards and email confirmation that if the box eats itself the cost is on them.
Overall, car is much better - Still waiting for a few more parts that could not be over-nighted to arrive but so far I am enjoying the car.
Did a read on the ECU this morning (ECU must come out to write though) so should have some mapping on it within a week or so.
