04 A8L is bouncing all over the place like a 62 impala with no shocks! Rear end is jacked up 8-10 inches in back.

Any suggestions would be appreciated. Thanks

You can have a air leak in the front suspension. Mines did that around 60k and that is what happened.

Do you have Stock Links on the Car? Did you change anything to the suspension? If not Try to get under the car in the rear and take a Look at the rear adaptive ride height sensors. You can see the sensors without jacking your car up. First Check to make sure the link is still connected. If so check The Angle of the Sensors that is held up by the link that is also connected to the rear control arm, sensor should be pointed toward the middle of the car not toward the rim.
This happens to me sometimes i jack my car up to do something under my car. The Sensor flips the other way(because i have Modded Links) and when i put the car down it slams the Front and Jacks the rear high in the Air, because the sensor thinks the car is way low when it is flipped toward the outside of the car.
Hopefully i helped.

You should stop and turn off the car for a little while - maybe 15 minutes. Then try to restart it and see if the suspension resets itself. Hopefully that should solve your problem. That has worked for me in the past when the yellow limp light comes on. Otherwise, you will need to take it to a dealer in Atlanta.
