digital mgp reset 2004 325i

hello, I'm new to the site, can anyone me help out with how to reset/correct the digital mpg reading?



#1 question right now is:

2004 325i-- I have the analog/needle MGP gauge and a digital mpg under the tach. the digital never changes mileage even after I hit the trip reset. it says 20.6 mpg forever,,,and yet I am getting much higher mpg per my needle & gas purchases.
