It's a bit of a long shot and hard to say without experiencing symptoms in person. Could it be climate control fan touching the casing?
I had kind of similar experience on Q7 after replacing climate control fan. Starting up, fan running at slow speed no noise; not sure if there was noise when driving and speed pushing more air through fan and making it spin faster and touch casing but me just not hearing because of other noises when driving. Or maybe it was braking forces shifting fan wheel just a bit so that it touches casing when braking but I could hear noise coming to standstill and it would stop after couple of seconds of being stationary. Taking it apart and reassembling making sure everything was seated correctly made it go away.
