04 mk111 air suspension help needed detailed checks in post

04 Range Rover MkIII was just purchased, eas system would work fine but front left would leak down in a few hours. I replaced the strut with one from Arnott. Had a completely dead battery that was replaced and it seems problems have developed with the EAS since replacement. I have used the all comms to read system last weekend it came up reservoir pressure static when filling that wont clear and got compressor temp rises when compressor not in use, that fault clears. I took the pressure valve out of the reservoir tank and released a lot of pressure it was full, no help, jumped compressor it runs but releases pressure out relief valve “t” in spare tire carrier area, never makes it to tank. I took to local shop they checked all power and air lines and they are good. They re-calibrated the system 2x, it’s on its stops now and system is still inactive. He said the eas ecu needs to be reflashed with a software update. Any ideas? Thanks, Joe

remove the L shaped relief valve in spare tyre well mine was doing the same last year the air bleeds out of it before it gets to the reservoir.its worth a try
