Either relay has stuck closed (under passenger seat) or if the dispaly says EAS fault then the you may have a ride height sensor faulty (look under rear or front axle, it connects body to axle) or also could be air compressor exhaust valve stuck open. (passenger side under bonnet look inside black box, find valves and compressor. remove exhaust valve and replace for a new one) Disconnect batter and reconnect after 30 mins, this might reset the problem. If all else fails, check the air bag springs for leaks.
