Had this rattle on my 7 R ,under load low revs ,marble rolling around sound ,sometimes buzzing , Crewe VW sorted it
the actuator (there are different types ) was loud then went to a sort of broken sound .
The cure , remove the sound actuator from the bulkhead and Insulate it and refit , It's not as loud or harsh and no rattles ,
however with the screen acting as a big speaker I have had some weird sounds all cured by checking for loose stuff in
the cabin which all turns into dash sounds ,like 5x £1 coins in the bottom of a cup holder centre console fine for 500
miles on the rubber mat ,then put a can of pop on top tight in the holder and you get 20 Morris dancers performing
behind the dash

other things CD in glove box ,seat not fully locked on slides ect ect ... .
It is possible on some models to turn the actuator down via VW plug in settings , hope this helps guys .
Save your dash if I were you
