Hi. As it says in the title, i currently have an A3 2.0 Tdi 2004, but due to a new addition to the family need domething bigger. Been looking at A6's, most have been the 2.0tdi, what are peoples thoughts on thid engine in a car this size, does it shift ok? Is there anything i need to look out for? Been looking at 2006ish models, and probably will go for an s-line.
