Hi guys A while back I stumbled upon this. Not sure if it has been written about here, so I am putting it up for you. The product info can be read here http://www.gfb.com.au/dv-plus-diverter-valve-for-late-model-vag-and-euro-applications I have bought it my self and it works. I had the old G version DV running on K04 APR setup. The stock DV work ok but was leaking and made a lot of sound. this baby does make the system sealed and no sound is released and I am having the Carbonio intake. There has been made two editions to this DV+ valve. Make sure to get the rev. Version with new spring. You can read more in my thread started at golfmk6.com forum.
