my dec 2006 has only 6800 miles no the clock and am really happy about that !

You, too, need to get out more!

imo cant go wrong with shell helix ultra in most vag engines (petrol) ??
Firstly, I'd be a little more specific in that statement. For example, my database serch shows
eleven different types of "Shell Helix Ultra" - ranging from a 15w50 which only meets the obsolete 501.01 standard, to a pre-FSI old skool 502.00 5w40. It also includes a "generic" or "one size fits all manufacturers" brew, and completely irrelevent Mercedes-Benz only and Vauxhall-only oils, along with the correct (in our specific instance) 504.00 spec oil. Furthermore, it also includes the older 503.00 LongLife 2 spec oil.
So, there like all oils, with your comment, there is a very high chance of "going wrong". The devil is in the detail, as the old saying goes.

At the end of the day, though, why not stick with the very oil which was developed in sole partnership with Volkswagen - that being Castrol?
