Happened several times during last few days. The light would go away after restaring the engine but would come back after few minutes of driving...
Two days ago was ON constantly but car looked leveled evenly
After reading some posts here decided to check the fuses in the glow box - both were ok. At that point I thought I am @#$% and will need to pay big $$$ to the stealer but I remembered that here was another fuse box in the trunk which also had 2 fuses for the level suspension and I was "lucky" fuse #87 (30) was burned - replaced it and no error message any more

CHECK ALL FUSES BEFORE CALLING THE STEALER
