check air suspension light
 

Yesterday while I was driving the check air suspension light came on after about 20 miles. I reached my destination and when I made the return trip the same thing happened. Is it dangerous to drive in this condition? The air bags hadn't collapsed. Could it be electrical and heat related? It was 95 degrees here in northern Virginia with high humidity. When I turn the car off the light goes off for a while. Richw

you might have a leak coming from your air bags, is your rear end sagging?
as far as you can tell can you hear the air compressor kick on?
turn your air suspension off jack up rear and spray soapy water on your bags check for leaks.
you can also spray on the air lines going into your compressor.
good luck

Mine does this once in a while, from what I found the ride height sensor needs to "check in" every so often and if it doesn't respond the alarm can go off.
I never had sagging and replaced my pump but it still happens and it seems the system does not release the air when this happens and door is closed.
Have not gotten around to changing my sensor yet but this could be your issue.
