Advice on A6 purchase

[stevehall]

I have a A4 at the moment and I am thinking of upgrading to a A6.
My ideal car is a 2007-2009 A6 Avant, Quattro, 3.0l TDi, Manual, with lots of toys
My questions are, is there anything to look out for on the 3.0 TDi units? Any major problems?

no ideas on engine but the lemans is probably the most loaded 3.0 quattro.
