Land Rover Repair: 2003 RR suspension, mail order, air suspension

Question
THE FRONT OF MY RR IS SITTING LOW AND THE BACK IS SITTING HIGH. AND ALSO THE LEVELING KNOB ISN'T WORKING. I AM ALSO GETTING A MESSAGE THAT THE SELF LEVELING ENABLED AND THE AIR SUSPENSION ENABLED. WHAT CAN I DO

Answer
What you have is an air suspension that's filled with moving parts, all of which are starting to wear out.  You have to make a decision - fix the air ride, or convert to coil springs.  As these trucks age the suspension can become a huge expense so conversion to coils looks attractive.  If you want to fix it you will need a dealer or specialist with the proper LR test system to talk to the air suspension computer to see what's wrong.  If you want to convert you can buy kits from the big mail order houses
