I'm thinking to buy a6 but there are two cars that i'm watching on the market. One is 2005 with 240000km from Germany and the other is 2006 (s-line) with 280000km from Italy. Two of them have good service history. What do you suggest? Are there any problems with this type of motor?

Thanks.

 

You are not being ignored, but I doubt if you will get any (or many) responses from North America. That is a very uncommon engine over here, if it was ever available at all. My only frame of reference is my uncle's oldturbo diesel Mercedes, and it went forever. I would assume Audi diesels are as good.
