The previous owner had replaced the rear air springs with coils and then left the front bags on, but had disconnected the air lines and put in manual fill valves. I replaced everything and put it back to stock-- new bags, valves, height sensors, etc. When you start the car, the vehicle does not lift or level out (there is a small air leak that I still need to take care of). If you press the lift or lower buttons it will do what it's supposed to-- either lower, level out at access height, or go to off-road mode. What would make it not automatically lift up and adjust when you start the vehicle? We do not have a Land Rover shop around here and I do not own a code reader at this time. I know that it could be a lot of things, but what are some more common ones? I will say that if I go over bumps and the lot, the vehicle does react to them as-designed so I know the height sensors are working.
