After sitting overnight it will probably run 90 or so seconds. May run on startup for 20 or so seconds driving throughout the day but not every time

On the LR3 we just looked at, the compressor came on for a little while when we started it up. We raised and lowered the suspension a few times and drove it around and it came back on. Maybe had it running for 15 minutes before it came back on. Ran for 10 to 15 seconds.

Usually about 10 seconds when we start it. Otherwise very little when we drive it. Do you have any low corners when you come out in the AM? It'll generally fault if the pump is weak, but may not fault for a leaking air bag/strut.

If no faults logged on, I’d recommend an air suspension calibration. The corners begin to loose calibration and drift prompting the ride air control module to request an adjustment.

That raising the suspension 3 times would have depleted the air tank. That extra running is probably normal. Also a good test, if it was having a problem it would have faulted out and displayed amessage in the instrument cluster.
