Default There is no such thing as a quality BOV for an Audi.

Not recommended as they cause the car to run lean. If you really need the stupid noise buy a hybrid valve.

Woah, Imola congrats on the new car but I would advise that you slow down on the mods and learn a bit. Your ECU monitors airflow including the diverted air released by the diverter valve. If you vent that air back to the atmosphere as a blow off valve does you will throw off the calibrations and the car will run poorly. The best choices for an aftermarket diverter valve seem to be the Forge and the AWE. Surprisingly the OEM 710n valve is very good and is fast acting. I ran it for years in my APR 93 car with no problems. I have the AWE now and it is good but I can't tell you that it is better than OEM. I just got the urge to try one. Pay close attention to the archives of this forum. There is lots of info there. Many of the long term owners are on the other forum too. Lots of good info available there for the asking. If you are looking for performance gains , having your car chipped is by far the best bang for the buck. If you want it to sound fast, Get a Borla or an APR exhaust.
Sorry if I sound a bit terse. Don't mean to. Just trying to pass along the help that I have gotten over the years.

Or put on an open air intake like the VTDA. You'll hear the Diverter Valve plenty loud enough that everyone will know you have a turbo.
