2000 S500 Base is on the back tires and everytime i leave it for a while then start it it raises up to the correct height but the i put it in drive and it immediately goes back down on the tires. first i replaced the right rear strut to no avail. then i checked and replaced the fuse and relay. then I replaced the level control valves and then i bought a code reader and it says all 4 acceleration sensors are faulty and all 3 height level sensors are faulty so i bought and replaced the rear level sensor as that's the part of the body on the tires, and the car still doesn't raise. if i jack up the tire sometimes i can confuse it and it will stay up a little but if i press the raise button on the inside it just lowers. at this point i got really frustrated and dug into the codes a little more and it says that the rear level sensor is not getting power... so now i'm out of ideas and thought id ask. Thanks in advance!
