Yeti1976

Hi All I have recently purchased a new Q5 Sline + 177 Tdi with a manual gearbox. I have covered over 900miles and seem to be achieving around 34mpg. The driving has been mixed with approx. 50% cruising on motorways, I have driven it carefully to try to improve the mpg's but to no avail.. Just wondered if anyone else has encountered such poor fuel economy? Appreciate your comments. Many thanks.
