As far as I am aware a module that makes your car sound more sportier. I have now heard it on a derv golf gtd and sq5. Both making a vast difference in exhaust note

Direct quote from Audi UK website in connection with A6 bi-tdi:-
Thanks to an innovative actuator in the auxiliary channel of the exhaust system, the BiTDI A6 and A7 Sportback models don’t sound like they should be capable of such level-headed economy figures. The actuator system essentially consists of a speaker which imposes a defined oscillation pattern on the exhaust flow and transforms the typical TDI exhaust note into a more sonorous roar that is closer to the output of a high-performance petrol engine.
I had this on my last A6 (3.0 bi-tdi) but ended up switching it off in VCDS as the engine sounded throaty enough without it.
I found that the sound aktuator actually masked the twin whistle of the turbos.
