I just bought a 2000 S500, with around 105k on her. The two front shocks were being held up off the ground slightly by exhaust clamps fastened to the shocks themselves.

Once I got her home, I immediately ordered new shocks and installed them. The car still won't raise off the ground. Right before replacing them, as I opened the door to pop the hood, the pump kicked on like it always does. After putting the brand new shocks in, the pump hasn't kicked on once, and doesn't even kick on when I push the dash button. Is there a reset procedure to get the car up to initial level?

I triggered the relay and the pump works and pumps fine. Before replacing the front shocks, when the pump would kick on, the back of the car would raise right up so I don't have a pump issue at all. It pumps, but the car isn't telling it to.

I have the "Stop, car is too low" as usual, but that pump is not getting the signal to raise the car. Where do you go from there?

 

It could be on of your Air hoses is busted, leaking out air... check for air leaks.

 

I have a similar issue. I replaced all the components for the suspension (pump, air valve, all 4 shocks, on my 2000 S500 and the left side is about one inch lower than the right side both front and back. Do I have to take it anywhere to have the hight reset?
