Keep in mind, extended drain intervals have been made possible through the combination of;
1. New or revised engine designs.
2. Use of newer & advanced lubricant technologies.
3. Introduction of low sulphur fuels (95/98 is capped at 50 ppm from 01-01-2008, down from 150 ppm. Except for 91 - no wonder why it's so cheap).
If all three conditions aren't met, then on face value one should reconsider if your car is suitable for extended drain intervals .
Not as far as I know, but personally I'd be hesitant to use that oil over a 15k interval, despite VW's blessing, not to mention that not all 502/505 oils are equal.
Since the original post pertains to a new Mk6 Golf, if using the latest 504/507 oils and fills it with 95 or 98 as required, 15k intervals should be fine (considering the oil can potentially last for 30k under ideal conditions).
Of course, to confirm this one should take regular oil samples every 1k to establish a wear trend. But going on evidence from the TDIClub forum, 15k is certainly manageable, at least on Golf TDI's (as FSI/TSI UOA's seem hard to come by).
Remember, horses for courses.
