Land Rover Repair: 1998 range rover air suspension, range rover air suspension, overhaul kit

Question
80,000 miles complete failure of air suspension
electronics-not sure if rubber is leaking air.Repair or
replace with springs?No prior history of problem.

Answer
Repair is my choice, always.  Most likely leaks, which will wear down the compressor faster than normal, so the compressor needs rebuilt at the same time.  

Your easiest option is a full overhaul kit:
