2004 Sl 500 ABC deez suspension raising and dropping by its self
Hi. My 2004 sl 500 abc light warning thing came on like a year ago. There are no fluid leaks. The rear suspension sags after turning the car off but it takes several hours to do so. When the motor is idoling after like 5 min or so the car dropps. I noticed that the suspension is slowly raising for the whole 5 or so minutes then when it reaches a certain height it drops. I cant really tell if it does it when I'm driving but I think it does. I removed both valve blocks and replaced the o rings on the valves. Then I replaced the ride height sensors and those black round ball reservoir thingies and that did fukoll. Any suggestions?

You need Star Diagnosis, an iCarsoft reader, or a Foxwell NT510 Elite to read the ABC fault code which you obviously have stored. You may also find it helpful to see the control currents the ABC controller is outputting to the valve block, and for that there is no substitute for Star Diagnosis -- you can have a system for as little as $200.
