bmw x5 diesel
Self-Level Suspension Inactive I don't know what's this but allways has voice. please help
Could be a blown fuse or the air supply pump, ride height sensors are faulty, or air shock absorbers, etc. Your going to have to do some diagnostics to determine the real issue. What you can check by yourself, before starting the car after a long break try to push in to the front air packs. If they feels soft, there is a leak in them and requires a replacement.
Do you have the dual suspension of just single axle?
