2008 A4 TDI CR Quattro - True MPG

[Bob J]

Hi,

I'm considering a 2008 A4 2.0 TDI CR S-Line quattro. it's the 168bhp version and stated MPG is 47.9 combined.

I wonder if anyone can tell me what I can expect in true MPG figures as I drive 15 - 20k per year on motorway and A roads and don't want to be hammered for diesel.  

Also, any common issues with the quattro over the FWD variant. 

Much appreciated.  Bob
