Adaptive suspension knocking at low speeds

I swear I'm not crazy. At super low speeds, like 5mph or so, there is a very slight knocking sound from the suspension. You can hear it from time to time at higher speeds, but it's really hard to focus on. I can't get my dealer to hear it or understand what it could be, but I don't hear this particular sound on any of my other cars. Does anyone know what could cause this, so I can point my mechanic in the right direction?? Is there a point that commonly fails on the adaptive suspension?
