I've noticed in the two months of owning my 08 HSE that the air suspension does some strange things.

First, sometimes when I come to a stop at a light, a couple seconds after I stop I'll see the front lower down a bit.

Second, after getting out and shutting all doors, just the rear drops down a bit.

The first scenario I can see a bit of reason in (the EAS pumps up a bit under braking to prevent nose dive and then readjusts once stopped) but the second has me stumped. Are these normal behavior?

 

Those things are normal. The EAS does what it needs to do...don't argue with it! If it's unhappy, it will let you know.

 

Mine does the second thing. All healthy, no codes. If you get a leak you'll notice it overnight.

 

When you get out it drops to what is called entry height. Makes it easier for short guys like me to climb in.

 

The suspension is always self leveling itself. Don't worry

 

Levelling after coming to a stop suggests a failing height sensor. Is it both corners adjusting or just one? try to pay special attention to that next time. Do you have the nav screen? If so go to the off road screen and monitor your wheel heights, if any of them are constantly changing even when stationary then that is the bad sensor. If you don't have the nav screen, I highly recommend the GAP IID. I recommend it regardless actually, if you have to change a sensor it will allow you to re-calibrate the system

 

Both corners adjust at the same time. I do have the Nav screen and no wheel height fluctuations while stationary. I think this is just normal leveling as mentioned. Thanks all!
