Hi All, I have a 2001 LS 430 with air suspension. The suspension on the car never gave any problems whatsoever until I parked the car up for 12 months. When I restarted the car after this time the rear of the car was sunken to the ground and did not pump itself up as normal. I have been unsuccessful in trying to get anything to work. The fuses are fine, the relay is fine, the height sensors seem fine. Any help would be gratefully received. Thanks in advance.
