    your car 20 euros / 1.49 = 13.42 litres of fuel. 13.42 / 4.54 = 2.96 gallons. 120 miles / 2.96 = 40.5 mpg.
    Girlfriends car 200/2.96 = 67.59mpg .
    TBH 40.5mpg doesn't too bad if you are doing local trips . The A6 is a big car what kind of MPG are you expecting.
    Your girlfriends car is awesome, when you find out what has been done to that please post on here so everybody can have 1.0 litre diesel fuel economy.
    Being serious there are a million and one things that can cause a car to use more fuel, tyre pressures, cheap tyres with poor rolling resistance, sticking brakes, engine issues ( Turbo boost leaks, cam timing, Coolant temperature sensor fault, MAF faulty, VNT mechanism sticking, thermostat faulty, etc etc).

    Thanks for the reply . I drive both cars and drive them the same way all the time just to see if I can better my one to her car. I have swapped parts over like maf and stuff like that but still no change on either cars.have also replaced all vac pipes . Now the only thing that I put in to the car that wasn't from audi was a coolant temp sensor. Would that have an affect on any time. I have a bluetooth module thing and I checked it and my coolant varied from 85 to 94 .

    You could try some injector cleaner, when was the last time the air filter was changed. Really need to connect VAG-COM and do some real time checks of boost, cam timing etc otherwise you could just end up changing bits will nilly.

    update

    I put a new filter in maybe a month ago. With all new filters. Just done 120 miles again for 20 euro and drove the car between 60 to 65 mph . What's a good cleaner to use.
