Advanced In Car Technologies
My BE has been into Audi about this very matter... Its the front dash speaker grill.
It happens when I accelerate the car. Audi replaced the grill under warranty it worked for about a day and the rattle is back. Im starting to think its the part of the dash that holds the grill so it will be going back to get that replaced.
Also noticed my rear BOSE speaker grills are starting to rattle too.
Quality of Audi is truly going down hill...
