Land Rover Repair: Eas fault, overhaul kits, air suspension

Question
First off 99 RR 4.6
I was towing trailer and forgot to lock suspension. The car gave eas fault the pumped its self up and stayed up. It now has been up in highest position for a week. Wondering if a electronic something or other went bad in air block or a malfunction in switch. Sometime car will go down to normal driving position as it sits overnite but then immediatly pumps up when you start car to highest position also when you start car it always brings up eas fault. Car has not sunk down to the bumps stops though. Thank you

Answer
This is likely the standard problems with the RR EAS.  Leaky springs and a worn out compressor.  Sinking overnight is a sign of leaky springs, since it didnt' come up when overloaded there probably wasnt' enough air in the system to handle the extra weight, that's a sign of a worn compressor.

At that age a full overhaul is due on the suspension:
