Fuel consumption increase

I have a 2009 Z4 2.3 auto with 4,000 miles on the clock. Last week I zero'd the average fuel consumption readout, and since then I have only been in town, and the MPG reads 14.1! Yes, it is set to imperial.

I have not been sat in any traffic queues or hold ups. Surely this cant be right? Any thoughts/advice?

I'm out of the country. Has it suddenly got a lot colder? That would explain it.

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.
