Ive owned my a6 for 3 years and i thought i will document here all mods/fixes/problems/etc on one thread. I have lots to put on here so it will take some time but please comment/ask and advise if you know anything that i dont :)  The car is great!!! Audi only made 1000 of 3.0tdi lemans and as far as i know there are around 200 left ... they produced 15 in late 2006 so there is a chance mine is one of the first ever made :) https://www.google.co.uk/amp/s/www.autoblog.com/amp/2006/07/19/
