Rear air suspension - shims to adjust height?

[dochummer]

Mine must be idiots, because they insisted that there was no fix for it. I spoke with one of the local tire shops, and they say that they've adjusted the sensors before to level out a ride...but not specifically to raise or lower the vehicle. Do you have instructions on the recalibration that I can give to the dealer to see if they would be willing to do it? I do know that my d height is about an inch low.....
