I almost 'settled' on my gas mileage of typcally 13 mpg as inevitable (that's what you get when you drive a 2+ ton house on wheels).
Did some maintenance yesterday and read the scans (VAGcom).
Found that fuel trims are 10% lean (B1S1 partial 10.2%, B2S1 partial 11.7%).

I've had an issue going on with a bad MAF. After running around in circles trying to diagnose a p0102 (changed the maf, hunted down bad wires, hoses etc all to find out the maf we swapped for was also bad) I finally cleared that code and got my MAF back in order.
