I know their are many post on the BSH PVC Revamp how ever they are no longer offering that kit.

They are recommending the BSH Speedshop SP 2.0T FSI PCV Blockoff Kit. SP 2.0T FSI PCV Blockoff Kit - BSH Speedshop

Does anyone have any experience with it? It concerns me as it seems it is eliminating a flow that the engine was originally intended to have. Also I am trying to eliminate an rpm flutter 100-400 rpm change when cruising around 30-35 mph. Correct fix?

RPMs pulsing in 4, 5, and/or 6 gear when under light throttle? Feels like the car is surging a bit and usually does it worse when it's cold? I bet it's your torque converter. I have the same problem and haven't really found a good way of dealing with it yet.

I have the original BSH PCV kit, but I went back to stock when I started having fuel system issues so Audi could do all the extended customer service fixes. Haven't bothered reinstalling it yet because I'm still dealing with the TC.

Sorry to be the bearer of bad news.

Read this entire thread. The actual TSB from Audi is quoted on Page 3. http://www.audizine.com/forum/showth...-at-low-speeds

 

Oh, and to answer your original question, that looks like the same kit I have other than it being black now. I'd have to dig mine out and inspect it, but it looks very familiar.
