air suspension , need help please

[khalidlib]

hello everyone
I have a X5 2006 4.8is with the two axle air suspension. My issue is kind of different , cant find any one how had the same problem, i did look
usually the car air suspension lose pressure over time, when i don't drive it for a week or so
but when i start it up, the system wakes up, pressure is restored, the car levels up and we r ready to go, today how ever i started the car , it tried to level up , i was not paying close attention but after warming up and started driving , man that car was jumping , parked at the side of the road, went out to take a look, and the front of the car was so low, my tyers almost hitting the finder arches.
went back in the car and used the buttons next to the steering wheel to lift the car, i can hear the compressor running and something is clicking, but the front will not rise, no hissing sound from the front and no massage on the cluster, no warning lights, went to the back to check at the compressor, as to was about to stop working, an air hiss came out like a release valve sound and the compressor was hot to the touch
i don't think the tow front airbags got damaged simultaneously, yet i cant get them to fill so i can test them

any ideas would be appreciated,
thnx
