Appreciate all and any help in advance. 2014 LR4 60k miles. The Codes that are coming back I listed are at the bottom. Not sure if it is the valve block(s), compressor, leaking air bags, cracked lines, etc??

Summary of issue: suspension fault comes on about 10-15 minutes after driving every time. “Suspension Fault” turns off when car is turned off and back on. Car adjusts all heights to be equal as soon as i turn car on (rpm rises 80% of the time on idle right when engine is turned on).

After turning off car front right corner starts to lower (i hear what sounds like an air leak noise) - within 5 minutes that corner is down at access height. After leaving car parked overnight the back left corner is only height unchanged.

Took the heigh adjustable fuse out overnight and started at off road height. Results are....
