JUst bought Audi A6 2.7 tdi special edition quattro tiptronic
 

Having just traded my Range rover for the above Audi, 2011 plate with 73000 miles, i would fully appreciate any positives or negatives, problems or issues that these cars have, love the car already and work in the trade but not on cars, anything i should look out for at this age and mileage along with when do i service the tiptronic gearbox, thanks in anticipation guys.
