As per VW Australia I took it to another dealership this morning who heard the noise, then pretended there was nothing wrong and proceeded to inform me that even though he can hear something wrong, there is nothing wrong with the vehicle and will charge me for any time spent looking at the vehicle (car is less than a year old and under warranty)

That's okay, i'll leave the vehicle the way it is, only getting it serviced at it's intervals, not mentioning anything. If the thing ends up with some major issue. That's fine, they will be the ones paying.
