I Need Advice before i buy

[chrisb]

Thank you for the speedy replies, my mechanics friend was there when i called and he has an 06 A4 DTM and supposedly is an Audi enthusiast, He suggested that i would get better fuel consumption from a remapped 3ltr tdi
A6 Avant Than the A8 with the same engine,which considering the A8 is aluminium i thought sounded strange but it was two against one so i was fighting a losing battle. I think they believe that because there are so much more electronic controls and ecu's that this would be a nightmare if something goes wrong. I have to travel to Dublin every Sunday which is a 220mile round trip and i want to be able to travel in a bit of comfort with my Buddy and our two Kids and still have a reasonable MPG return. I have joined a couple of A8 forums to carry out research as i dont like to buy without knowing what i am getting into and if there are any serious problems that i need to be aware of.
