Peugeot 607 fuel economy drop

I drive a Peugeot 607 2.2HDI auto (this is my second one in a row). I was averaging 38 - 40 mpg but I notice in the last couple of months this has dropped to 30 -32 mpg. My driving style has not changed, the car is regularly serviced - there is no apparent leak - do you have any suggestions?

Possibly a clogged air filter.

Real MPG enables you to register the fuel economy you are actually getting against your make and model of car, its engine and type of transmission.

Every time you enter an average consumption figure against your car, the overall average automatically adjusts to reflect it.
