Thank you for this video, I have a 2012 Mercedes S550 that had suspension issues with the front end. I had the pump replaced, both front air shocks replaced, suspension valve block replaced all because the car wouldn't lift. After all that I found your video and that was the problem, the two sensors. The shop didn't think it was the sensors because it didn't show up on the computer. Thanks for the video, I wish I found the video a lot sooner, but hey now everything is new.
my 06 s500 sits real low in the rear. Especially after a a few really cold days. The rear passenger side starts to sag real low then the driver rear will start to sag. Sometime it sits ok for a week or so then it will start to sag after a few days of not using the car. What could it be?
