There are a few simple things you can check first:

*Ensure that you tyre pressures are correct.
*Clean you MAF Sensor. A simple job that will take 15 minutes.
*Make sure that you car is serviced and that the air filter is clean.
*Have you A/C serviced and regassed.
*Don't use supermarket fuel. Use something like Shell diesel.

Just a few suggestions, but I'm sure that someone else will be along shortly with some more tips.

Jim

Oh, forgot, check that your brakes are not binding.

Re-set the 'trip' mpg/computer if you haven't. See if that makes a difference.

As said above, check the brake system to ensure that nothing is binding. You should be getting 24-32 depending on how you drive (real mpg, not from the display)

Assuming a £1 per litre, that gives 6.75 gallons so 16.3 mpg you are not wrong.

may sound a stupid question but when it is really cold it takes longer to start would glow plugs have anything to do with it or are they only for starting only

Glow plgs are (as far as I know) only for starting but the FBH (fuel burning heater) helps get the engine up to temperature quicker. So is yours working?
