I was never able to get the programming done.

After disconnecting the compressor at the local wiring connector and otherwise replacing the air suspension with coil overs my ride height buttons flashed until I disconnected the switch. I occasionally get the lights on the dash, randomly about once a month. Goes off when I restart the car. Not a huge issue for me.

Considering the time and $$ put into trying to diagnose air suspension issues on an older car, I wish I had of just gone this route in the first place. The suspension has proved to be "OK" over 20k miles; a little choppy and definitely not an improvement over the IS sport suspension, but totally functional. The car LOOKS a lot better as I could dial in the ride height perfectly. I'm sure if someone took the time to fool with spring rates and compression adjustments you could get it nailed down pretty good.
