Last week I resetted the ECU to see if it will give me better gas milage. Well sad to say on a full tank a gas I only got 150. No one I know with a 2.0T has ever seen it that low before, so i'm a little confused. 1 dealership said thats normal the other dealership I called said there's something wrong. Maybe I did it wrong? Can someone gives me steps to resetting the ECU and also the battery I want to try the battery, but I can't find a thread that explains it well enough.
