We have zero consumption between changes. Zilch, nada, nothing.
The trick with the VW diesels is apparently to leave the factory fill in for at least 5k. Owners of older TDIs reporting high consumption tended to also be the ones who did a quick early change to a full synthetic. While the '09s require a full synthetic 507.00 oil starting from the factory, we still followed the old 5k rule and it worked out very well for us.
This engine takes at least 15k to fully break in, from our experience with them. Mileage is now starting to get in the appropriate spot (mid-high 40s on average).
It's a wonderful power plant, as small diesels go.
This mirrors my experience with my 2010 Golf TDI. No oil consumption, 13k miles driven so far. I am running 5k OCIs with the specified 507 oil and will continue to do so throughout the warranty period.
