You can remove fuse 5 from engine compartment fusebox. I doubt you'll notice any improvement in mpg and your heater won't get as hot in these conditions.
All vehicles use more fuel in winter particularly when it's this cold.
According to my handbook (05 TD4) that fuse also covers Engine Management and Transmission Cooling.
