If after start up, the compressor kicks on & off until the "check susp" light comes on then it sounds like you have a leak. There is a black plastic inline connector for the air line that is prone to breaking. It is located near the brake resevoir on the driver side. There are some good detailed posts on this site about air suspension problems. Do a search or post a new reply of where you are at with this.

 

Yes it's possible that line broke upon reinstallation.. or is leaking.

Also the front ride height sensor is on the left side.. maybe it got damaged or mis-adjusted during all of this.

You might have to let a dealer recalibrate the height sensors.. that should always be done after a torsion bar replacement/adjustment or replacement of air ride components. It may be all you need.

Yes you need a dealer computer/scan tool to perform this adjustment. After all you've been through with this suspension I don't think there's much else you can do on a self-repair basis. You might try spraying soapy water all over the air lines and the air springs and look for bubbles... like you would a leaking tire.

Good luck.
