Toyota diesel mpg?

[Ajones262739]

Hi all,
Bit of a wild stab in the dark for advice:
I have recently taken delivery of a 12 month old 6500mile avensis saloon: 1.6d4d (BMW?) engine.

Struggling to get much more than 52mpg at the moment, on what I'd consider to be 'combined' type of routes. (And on which the computer in a 10yr old golf diesel would show 65+mpg!)

Salesman says I should expect less than the advertised mpg, because it's not been fully run-in yet. Should I believe him, or is something wrong?!

Any thoughts?!

Good point: with hindsight, it may be fair to regard VWs figures with a certain skepticism, given their tendancy for not being entirely above board with environmental considerations.
