Are you getting this MPG from computer reading , could this be faulty ? To be as bad as that you normally cant fail to see what is causing it . Other factors if not false reading can be a thermostat stuck open or used for short journeys . As regards to air con , on any car this does lower MPG but not to that extent you are experiencing .You could check your air filter also .

Cant recollect a diesel car with that size of engine ever having such a low MPG without showing obvious faults which should have been easy to pick up with what checks you have already carried out . Could take to a good local diesel specialist for examination .
