Probably a computer fault unless the fuel tank level is showing you anything different.

This ^^^ although it also sounds like you've got it set to instant MPG as that's the only time you'll see 102mpg

Have you measured it over a full tank i.e. filled it, driven it, filled again and worked out the MPG the old fashioned way?

Could be a temp sender problem

My 1.4 16v also uses a lot of fuel but u'll get that because the 1.4 is always under powered because of the weight of the golf and ur always high revving to gain decent speeds. I know this because I do it haha.

Well if it is not getting to temp, it will not be helping.

You may have a thermostat problem.

Faulty temp sender  / thermostat means your ECU thinks the car is permanently cold and will therefore chuck fuel in to compensate

Get both changed along with some fresh coolant
