Hi Guys!

Looking for some general advice here...my brother is considering buying a 2013 A4 Avant 2.0 TDI (163ps) Technik...one of his other options is a Honda with which both he and I have had years of trouble free motoring ...so would like to hear any advice /opinions on things like dealer servicing costs...reliability..common issues.....things to avoid really..and just general do's and dont's with regard to this model?
Sorry this isn't a more specific question but I'm a member of another VM Forum and know that these are the best places to go for advice.

Many thanks in advance for any input
