I own a 2005 SL500 with ABC issues.
I am trying to learn/understand how the 2 ABC buttons on the center console function.
One button is an ABC on/off switch with a red light on/off.
The other button has a picture of the car with an up arrow & 2 on/off red lights.
How does it work?
Can you raise the car up/down?
Thank you.

If you have an owners manual it explains it all.

There should be no on/off button for ABC.

With one LED lit the car is raised approximately half an inch; two LEDs approximately 1 inch.

How do you lower the car?
Thank you

If you want it lower than stock you'll have to install a lowering module or lowering links. Lots of articles about both in these forums.

I changed the ABC pump & the rear accumulator & rear block valve.
The driver side is higher than the passenger side.
The driver side rear is higher than the passenger side rear.
The driver side front is higher than the passenger side front.
How do I correct the problem?
Will Rodeo correct it?
Thank you.

A rodeo will not correct that, however, the heights can be adjusted with a MB Star computer. You can also buy adjustable sensor links and fine tune it that way.

The button that has just one LED wil set the system in sport (light on) or normal (light off). The button with 2 lights controls the height in two different stages.
