Car was riding well then one morning hard fault. The codes I got were all 4 height sensors out of range as well front left valve permantely closed. I cleared them but the car still would raise. I checked the inputs info using my rovacom lite and everything looked good except for the inlet and exhaust switch they were both open. That can't be good. Im guessing that mean the air is being released from the system as fast as its goin in? Anyone experience this problem, if so, how did you address it? Thanks.
