Where is all the mileage I am getting to average the tank at around 38 if I am always getting such low mpg. Sorry if this is a stupid question im just a little confused by this.

The Scangauge II doesn't work well with the tdi, even if you get the mileage close on the highway then city is way off or the other way around. I returned my scangauge for the that reason and tech support was useless.
