sorry the title of the post sould be low mpg. Hello everyone i have a audi a4 2.0 fsi 53 plate auto,when my fuel light came on i reset my fuel computer to zero put 4 gallons of petrol in (18 liters)drove around slowly trying to get the most mpg when the fuel light came back on i covered 102 miles,which works out to be just over 25 mpg which i think is very bad.i have done a diangnostic check on the car and no faults were found,i would be very greatful for any help.
