Every engine is different. My 2.0L TDI in my Jetta didn't consume anything at all. Oil level was full at every 10k oil change.
As long as you're nowhere near 1 quart every 1,200 miles, I wouldn't worry too much about it. VW probably won't do anything about it anyway unless you can prove something obvious, such as external oil leaks or turbo bearing leaking.
