I heard a leaking air sound the other day from the front left side of my 04 range rover, im thinking the airbag or hose split and the dash show suspension inactive, but then i lifted it and it has stuck there since, no lights on height control knob.....I'm going to look at airbag tomorrow, can i disconnect hose and air up with home compres to check where leak is and then once i find, does a dealer have to reset the ecu to get working again, i have disconnected the battery, but didn't fix it to where i could check.....
