poltern VA with damper adjustment comfort

Good evening. Would very much like to know why the Phaeton at the VA is slightly polished, as soon as you put the dampers on comfort, that has always done so. Is it the famous poltern, which some auto testers have always noticed with the A8, Phaeton etc.? In normal driving you do not feel that, for example only on lowered channel covers potholes etc. For this I imagine that the noise becomes less during the ride. I would describe this in about…ponk ponk, with very slight clattering behind it. TÜV had recently happened in 5 minutes, without defects. I’m curious with whom it is still so.
