I just bought an 03 allroad. The fuel mileage is absoltely horrible on this thing. Like 17mpg. I knew it wasnt going to be great but not this bad. Ive got a check engine light which I know isnt helping but Im trying to find an Audi scan tool. Is there any other things I should be looking at with @75000 miles. Ihope I can get the mileage up or my wife is going to drive me nuts (shes used to 30+ mpg. please send help ASAP)
