My jetta has been getting "okay" mpg since I bought it a year ago. It's 5 speed and I average about 39mpg, even with mostly highway driving. I use all the proper driving "techniques" so I'm a little puzzled. I just got a vagcom cable and I'm wondering if there is an diagnostics I can do to see if anythings out of whack.
My timing is slightly advanced from the center line and injection quantity has been adjusted to 4.0. Anything else I can check?
