Airmatic visit workshop light comes on (car with arrow). Caused by faulty relay? on 2003 Mercedes-Benz E500

Car sits level, not too low, no sags. Sometimes responds to pushing "Raised" level button push, sometimes says vehicle is raising, but it is not. Suspension Style system works normally; car raises when in #2 sport suspension mode.
