2006 Range Rover Air Suspension Issues With Codes

I have searched the forums for a good hour or two, and haven't seen anything that answers my question.. So here is my question. How likely is it for all 4 ride sensors to go bad at once? None of my wheels are bouncing on the 4x4 menu. BUT in my code reader I have 0 inches on all 4 ride sensors. I also have 2 codes, but no codes pointing to my sensors being bad. I have " C1A00-54 " and " C1A20-64 " Which translates to "Control module" (54) and "Pressure increases too slow when filling reservoir" (64) I am not sure which part is bad here? What is causing my suspension to not raise/lower. The back of my SUV is pretty low (after jacking up and changing the wheels), and every once in a while I will get an error "Suspension fault" or "Vehicle lifting slowly" the height adjuster in the center does not work anymore. And my vehicle has not moved from its current height after changing my wheels for almost 2 months now. So nothing is leaking I know that. I can hear the compressor (Maybe?) randomly turn on sometimes if I am outside doing something and I am near my rover. Any ideas where to start? Here are pictures of what I see.

Anything else you may need to know, or need pictures of anything else to help me find this issue just let me know. I would be glad to provide additional information if needed.
