Air Suspension, HDC, Transmission Error, ABS error on Range Rover Spport

This morning I switched my Range Rover Sport HST on and the dash lit up with various Errors.
These errors stayed on until i got to work. I turned the car on and off and the Errors cleared but the Transmission Fault error remained.
A search on the internet brought up loads of potential problems. One of the issues was checking for battery faults which I did, and the battery did show a low drain that needs to be investigated.
Other possible causes could be damaged sensors, damaged pipes that could results when the RR wheels a dangle when raised on a ramp. Air suspension bag that might be leaking, misaligned wheel tracking, a fuse blown somewhere or ultimately a wrecked Haldex suspension.
Anyone come across this fault before, please provide suggestions in the comments.
