330d Poor Economy

[stugolf]

Hi Guys

First winter with my 330D and I know the weather is very cold and diesels don't like the cold weather but in my E90 Pre LCI I'm getting 22-24MPG and 31MPG on a reasonably long run, is this normal?

The car is an auto which I know saps some MPG but I never expected it to be so bad!

Yes its mapped and is left outside, think the thermometers need checking as its not running up to temp after checking before

I'm just checking from the read out and the miles left per gallon, the temperature is definitely not correct, never seem to hit 90 so that's what I need to address before I get DPF issues
