air suspension goes flat at random

front air suspension goes flat
it may work properly for days, then it will go flat overnight or even while driving down the road ! it always airs back up after a while . no rhyme or reason to when or how long .

Could be numerious things. Need to have the dealer diagnose. My airmatic pump and central valve were replaced (pump twice) just before warranty expiration.

Yeah, I just ordered the bags from arnott. They told me the struts are back ordered due to high demand. They aren't getting enough cores to rebuild to meet the demand. They now offer just the air bags.
