Hello. I have a 2004 s430. The air suspension stays on after the key is removed and doors are locked. The relay in the right front fuse box checks out ok. I am trying to figure out if the control modules in the left front fuse box has a fault and remains on or if there is another issue keeping the system on. The different suspension modes work fine and the suspension lift feature works. No error codes for the airmatic system in the computer either. My understanding is the airmatic should be asleep until either a door open, trunk open or key insert. Any help on this would be appreciated. Thanks!
