What PCV do i need?

[RichF83]

Hi all,

I have a 2006 2.0tfsi quattro. I recently had a check engine light come up with an error fault for PCV. I've NOT noticed a decrease in performance or lumpy running, however there is blow by from the dipstick and a noticable increase in the already high oil consumption. Wondering if anyone knows what the OEM replacement part number is if I do the work myself? (I'm assuming its not really worth going after market, correct me if wrong). And secondly, can anyone advise if this is likely to have done any significant damage to the engine?
