I know temps can be checked in the hidden menus but I don't remember how but any how. According to an online real mpg site it would seem I am getting less than 40mpg on my pre lci 320d even though the obc mpg is usually between 42 and 46. Should I consider getting the relevant thermostats changed. I usually stick £30 in and always get a minimum of 160 to 170 miles although as the light comes on at varying times as in anytime from 70 miles left I suppose there is a little bit in it but nowhere near enough I think for me to be averaging 40mpg. Mainly 30 zones and a little bit of B roads in my daily commute in very little traffic. Thoughts please.
