I replied to one of the other threads about this, but I figure it wont hurt to start my own thread and post it here as well. I need some Ideas...

I have a 2000 S430 that I picked up in Nashville about 6 months ago. It has 120k miles on it and I am not sure what has or has not been replaced on it before I bought it. I would LIKE to think that it was very well taken care of due to the fact that it was originally owned by the CEO of Sony Music Nashville and it looks AMAZING for being 11 years old...

recently, I have noticed an issue. Some mornings (almost every morning) the rear of the car is completely lowered and the red DO NOT DRIVE light is on. I sit, and 30 seconds later the light goes off, the car has come up and I am on my way... HOWEVER, some times its the front right wheel that is down and the rear is raised up... I'm guessing a leak would make it go down EVERY time... a few times, the entire car seems to be low (rear more than the front)

the other night, I went outside (rear down/ car off) and opened the trunk and the car raised itself back up. hasnt done this since that I am aware of.

also, I can walk over to the car at anytime (car off) and open a door/trunk and I can hear what sounds like air releasing from the front right side. any Ideas what this stuff could be? any input is awesome

 

Check lines to the compressor, my car has the same kind of problem before and problem was solved replacing the lines to the compressor.

 

its the air shocks for sure. whether they need to be replace or the line is leaking its the air shocks. hopefully for you its just a leaky line. i do know that those s's need new air shocks at about 130k miles.good luck
