...and while you in there changing the air filter element, change the engine breather (PCV) too. It's critical for the health of your turbo to get rid of the old "loo-roll" filter type and replace it with the newer "vortex" design.

And I'd echo nice1guv's comment about the current MPG reading - the range is based on the current MPG reading so if it's high (as when you have been running around town) then the projected range will seem low.

But I'm guessing you know this and I'm also guessing that your issue is a real increase in fuel usage and not just a cosmetic one. I don't think I've ever seen a range of only 750km when the tank is full...
