Hi people, does anyone have this problem? I normally dont have the mpg on the nav screen so just discovered that they don't match up.

 

There are different MPG settings. The one on the nav is the overall average, and the one in the cluster is programmable to overall average, mpg since start, mpg since fill up, etc

 

You can toggle to another mpg average with up/down arrow on right hand side switch on steering wheel which will match Nav mpg. The one you're showing on dash screen is Average after refuel. It always reset after each fill up.

 

I guess i totally forgot that the mpg settings can be changed. I'll give it a try, thanks!

 

Nav = MPG after reset
