Q5 3.0TDI, new owner questions?

[PLuKE]

Hi guys,

I am going to look at a 2013 3.0TDI this weekend with 80k on th clock, full history and recent service and gearbox service too.

I currently have a 2013 330d Touring, which for the power/size is great on fuel.

My questions are really....

How is MPG?
What should I be looking,listening and checking for?
What’s overall reliability like?

Many thanks
