Stuck valve in the valve block not allowing air into the air bag, or a break in the wiring to the valve in the valve block, or a split pipe to the air bag or a split air bag.....not a lot else!
 
So i started up the car and the front right strut came up when i tried to ride away the car made a really strange noise for couple of secconds and the strut went down... I just cant believe its the strut thst has a leak but thats the most logical problem. Any idea how i can test this best? Im nit willing to buy those expensive things and not solving the issue...
 
If its a big enough tear in the bag you will not hear it hissing out.

Try and feel around the whole bag when the compressor is running

Mine did the same, strut pumped up and then a loud hiss and the strut deflated
 
ThaNks problem is that the bag isnt pumping when i drive like 300 meters. When we did the calibration with autologic the car gave air susp inactive with reservoir pressure static when filling. than the compression went to 0;3 and we heard a very loud beep coming underneath the airtank we coukdnt find anything.. Put new compressor and we calibrated the car and went out for a test drive with the old compressor. Car drove 20 miles with no problem. Went home by the highway and guess what? Front side was sitting lower but still pumped up... I really dont have a clue..maybe the valve block?

Splits in the airbags open and close with movement.
 
So u think its the airbag?
Impossible to be sure from here, but would seem likely from the symptoms, there have been quite a few failures posted on here.
On a P38 the easy way to prove it would be to freeze the suspension, take the pipe out of the strut, manually inflate it with a schrader valve and see if it stays up. I've no idea if this can be done on the L322.
