Suspension light on (car with arrows arching over car and below yellow car. System information says Suspension Fault, not able to raise or lower car.
Last time this light came on (a little over a year ago) the Land Rover Dealer told me the air suspension system was clogged..or some thing along those lines....Replacing this was around 2k.

Vehicle Height Sensor light has been on for months. My service guy put new tires on and could not do the alignment due to this problem. He said I have to go to the dealer. Going to watch tire wear at oil change and watch. These sensor lights can drive you crazy! Also, my gas gauge is broken and to fix is $350, so I just fill up every 325 miles, no problem.

Shortly after we bought the two years ago the problem started. The dealer said it was the air compressor,but the compressor is working.
