Hi all,

I have seen a few on here saying they get high 40's MPG from their 1.9 CDTi's but I'm struggling to get 41 no matter how I drive (including long runs).
I'm now starting to suspect I've got a problem.

Has anyone any ideas?

P.s, The ECU was reset the other week at Vauxhall cos they reckoned it was "flatspotting" on a road test could this have contributed?
