AIR SPRINGS (sls)PROBLEM.... UPDATE
 

air springs (sls) UPDATE
[hr]

i have searched and read all the threads on this subject but i still am unsure of my problem, i have a 2000 td5 discovery , i have checked and double checked the springs for leaks, but if i park on a slope (NOSE UP) the bags deflate right down to the stops in about 1 min.i have checked the height sensors and they seem to be ok. if i park on the flat or down hill there is no problem, any ideas please.
UPDATE..today i drove my car over some very bumpy terrain i noticed after this that the springs had deflated whilst driving (something to do with the road maybe?)

also if i do park on a hill and before i get out, if i inflate the springs with the yellow height button a little bit then return the height to normal i can leave the car and the back dose not drop.
i hope this extra info will help someone solve my problem.[/align]

Your are going to need to have a mechanic with the proper scanner, check for SLS faults then recallibrate the system with his scanner.
