right now it is so low i cant drive it anymore...

i replaced pump, relay, fuses, checked struts...i was looking for any leaks - there is none. computer error-C1517 (critical vehicle level at front axle). the pump doesnt work at all on its own (i opened the old relay's plastic cover and made the pump working by pushing the relay's blades together), but the car doesnt rise at all

what are the chances that it is the Airmatic computer unit?
any other ideas? i would be grateful for any!

cheers!
