I recently purchased a 2005 E500 4MATIC Wagon with 72k. The suspension seems to bounce a few times when going over dips at low speeds. I had the same issue with our 2001 E320 Wagon that was corrected when I replaced the actuators - but that was a hydraulic suspension. The car appears level, doesn't rub and it seems to raise as expected when the the height button is pressed. No codes are present. I have two other suspension modes and neither seem to affect the bouncing. Thoughts?
