Just a quick follow-up for those who have done or are going to do the PCV replacement themselves: Even if you don't immediately get a code for the PCV system with the older software loaded, you will at some point. Mine took four months before it started showing up, however it was a soft MIL, no CEL at any point. It has been functioning correctly with zero oil consumption, even when driven hard. The ECU however needs to have its parameters for the updated PVC operating specs updated so it doesn't think it's failing.
You can either get the software updated by an Audi dealer, a VAS-owning independent shop, or from your tuner. If you are already tuned, you are golden.
I went the IE tune route and that resolved my PCV soft code.
