(1) You cannot turn-off the auto-EQ background noise compensation and it is implemented terribly. Especially at lower volues when there is a perceptible jump in volume when engine noise increases or lowering in volume when you pull up at a junction or ambient/engine noise drops quickly. I have had the car in to Audi to look at - their engineer can hear the the changes in volume that I report but the company line seems to be to assert that it is a feature. This is true, but it is a feature that has been implemented in a p**s poor manner.
