40 TFSI Avant - what mpg to expect?

[Mr Bump]

I am looking at a 24 plate Avant Black Edition 40 TFSI and wanted to ask if drivers of that particular engine/car could advise their mpg?  Most of my driving is in towns, 9 miles each way per day with the occasional motorway run.  Ideally I would love a diesel but I simply don't do the miles for it.  I previously owned a Q5 45 TFSI which I absolutely loved but it was prohibitively thirsty, so am keen not to have that issue again.

Thank you.
