I had my wheels powder coated last Friday and the car serviced at the dealer and on the way home got a big warning on dash that a "suspension raising and lowering is not available". Also, the little indicator light on the console (in-between the up and down arrows) was not lit. I turned off the ignition and restarted and it went away. Could a bad module be causing this? I would hate to have to drive back to dealer which is 3 hours away. My dealer just texted me that "without giving a symptom, maybe a height sensor or compressor???
