2001 S55 ABC fault,rear passenger raises only after driving, but stays lifted once up

Hey Guys hope all is well in everyone's neck of the woods! Need some advice only an issue I am having.

I have a nice 2001 S55 AMG with only 112k on it. ABC visiit workshop light in "white" is on: Whenever i go to start the car the passenger rear will never move from the position it's in unless it's already raised and I hit the "raise button" "off" button: which causes it to drop all the way down, once lowered the only way to get it to raise is to start driving. Car raises fine once I start to drive and unless i turn the car off and hit the "raise button" to the off position it never changes.

From hearing my issue can anyone assume what may be going on?

Odd problem. The only suggestion that I have is to check the ride height sensor in the center of the rear anti-sway bar to ensure that is is properly connected both physically and electrically.

Got it! The arm on the Rear passenger level sensor was completely off and bent. Bent it back straight and used pair of pliers to squeeze it back on. Fired car up and up she went,BUT...passenger side is too high now , can someone tell me the correct way to adjust the rear level sensors?

Also does both of the connecting arms suppose to be straight in the rear or are they different, reasons being, I thought the one on rear passenger was bent and straightened it out as best as I could

Needs a part number for the rear arms that connect from control arm to level sensor,Anyone? Thanks!!!

You might try making the arms look the same (or mirror image) and see if that levels things out any.

Any idea where I could get the part number for the arm that leads to the rear sensor?

The rears are pretty easy to adjust just by bending the lower mounting bracket. Not the right way to do it, but I've seen it done plenty.

I was looking up the source for knocking sound and pulled these part numbers. They are for a 04 S430 non 4MATIC.
