A5 Sportback 2.0 TDI Quattro poor fuel consumption

    So I’ve just sold my 2009 A4 Avant 170 2.0 tdi which I owned for 5 years. It would return around 44mpg of mixed driving and 53mpg on a motorway run. I’ve replaced it with a 2012 Facelift A5 sportback, again the 2.0 tdi but this time the Quattro. Now I know the Quattro has more moving parts but I can barely get over 35mpg out of it even on the motorway which to me is dreadful.
    Could there be a fault somewhere or is this what they are like?

    I had the 3.0 A4 TDI quattro and got 40+ average.

    Yours doesn't sound well

    Has your car had the recall? Plenty of people complain that it effects fuel consumption.

    I got my A4 144bhp & A5 177 bhp 2.0 TDI'S mapped, BluFin Stage one, and noticed a slight improvement in town driving mpg.

    Unsure if it’s had the recall. It had a seized front brake calliper and faulty alternator when I bought it and put the bad mpg down to that. However having those jobs sorted it’s still as bad. I think I’ll get it in for diagnosing and oil, fillers etc change and take it from there. Thanks for the reply’s

    When did you buy it?

    Was it from a main dealer?

    If it was recent and main dealer then they would have applied the update.

    Main dealer should be able to tell you if it's had the update.

    Changing the fuel filter is a good shout, tends to be overlooked sometimes if it's not main dealer serviced.
