Airmatic riddle

Hello all, I have a 2004 MB 400 CDI with airmatic. Front airmatic was changed 3 yrs ago and back 2 yrs ago.
Suddenly right back started to hang so I suspected a broken bladder.
The suspension could stay raised in normal height for a day or 1 hour. But if I set the car in ride high mode it stays like that no sagging and no problem
. But of course I don't want to drive like that.
When using normal mode (not raised) and the car has been parked if the airmatic is low, when I then start the car I can hear at the right back wheel almost like an steam engine.
If I then push the ride high button it starts to raise and all is fine. So do you guys think its the bladder or not?
Any thoughts or suggestion would be appreciated.

Regards,
Joakim

if it is the air spring it does not matter what height you leave the car, it will drop.

Sounds it is some other problem.
