ok to start i know there are countless threads on this topic so please bare with me, yes i have done a search before posting i just cant seem to find a situation like mine

so i bought my LR3 about 6 months ago and it had a "suspension fault normal height only" everything i read had said the dryer was bad. i didn't worry to fix it because it would raise and lower just fine and the fault didn't come up for about a minute or so.

about 3 months ago i started to notice the nose of the truck lowering every night. ( bad front valve block) i didn't worry to replace because it was fine during the day.

fast forward to a week ago and i get sick and didn't drive the truck for about 3 days. walked out and cranked her up and the "suspension fault " came up quicker than normal and wouldn't rise. a few quick shut offs and it popped up " suspension will raise once cooled" or something like that. finally after letting it sit for a couple hours trying it and then repeating the process all day i finally got it up.

went out of town for a few days and now she wont go up at all. suspension fault almost immediately after cranking. but now it doesn't even say normal height only. Just Suspension fault.

felt the compressor motor and it was very hot.

went ahead and bought a new compressor and relay and front valve block. changed them all and the fault still shows up. the compressor will run for about 10 seconds and then the fault comes up and it cuts off

also i have Johnson rods, not sure if that changes anything.......

You'll have to plug in a dedicated tester to read fault code(s) maybe there is one related to some other part than what you've changed but if it isnt you have to clear the ECU memory from the stored codes to get rid of the warning. The D3 can't be fixed based only on the presumption that it's the same thing like on others just that it's common cos in your case might be something else.

from the workshop manual:
"Use the approved diagnostic system or a scan tool to retrieve any diagnostic trouble codes (DTCs) before moving onto the symptom chart or DTC index and starting repair procedures.
Make sure that all DTCs are cleared following rectification.

you could have rather spent on a GapII tool and find the real cause of the fault than randomly on new parts which might not be needed :(
