Hey guys,

I was standing outside today and i heard my suspension start to pump up. Is that normal? I was under the impression that it wasn't supposed to run unless the car was on. Thanks in advance

no, thats normal (well kinda) the suspension computer stays on for around 2 hours after the car is shut off to maintain vehicle "parked height" so it kicking on is "ok"...................but in my mind, it means that there is likely a small leak causing the comp to come on to maintain height

It could be a leak, or like where I live its REALLY getting cold out. When I dive to work, ambient heat of the car heats the bags. As the car sits, the air in the bags cools a lot and the car sinks.

also a poss, just like your car tires, hot air expands and cold air contracts

Thanks guys, I dont think the bags have a leak but i could be wrong. I was parked sideways on a hill and i think that caused it to level out. I just didnt think it was suposed to run after the car was off.

It will, and if you do have a leak and don't address it you too will be looking at a fried compressor, dead battery, possibly a toasted alternator, or any of those awful things. To verify, turn off the air ride switch and see if the car stays up.
