That is low. Firstly dont go on car trip computer, used fuely (see signature below my posting) to record your brim to brim mileages and fuel used.

Also, clean egr valve and MAF sensors, and reset your ECU to reset the whole settings and see how it goes.

I do all these things with major service.

I'd second all the advice here. I bought a d4d a few months ago and cleaned the MAF

and ran a can of cleaner through and I get 50+ mpg combined actual fuel used.

I think the MAF had the biggest effect. Cleaned it with a £3 can of electrical cleaner

from Halfords.

Incidentally, how do you reset the ECU?
