    Went up north the other day to Preston from London and was driving sensibly, averaging around 80mph or was it 70 ;-) on the motorway. In 6th gear most of the way but no matter what I did I couldn't get her over 30mpg, is this normal? I would have thought I would get better then that....What do some of you guys get on a stretch in your TFSI Quattro's?

    That does sound low - mine does 32-33 at a steady 80 on the Motorway (goes up to 35ish at 70)

    Mine is a 56 plate (2007) 2.0T Quattro Avant Special Ed

    Recently did just under 1400 miles up to NW Scotland, round and back home and brim to brim over complete journey averaged 30.8mpg.
    Good mixture of Motorway and excellent A roads, travelling at about 80mph on Motorways and 60 to 70 ish on A roads. Never seems to be any different. Engine is BUL 220 BHP and Quattro transmission.

    Thanks for all your replies.

    Where do I start to investigate a possible issue with it?

    Car is remapped by AMD, has the revised DV fitted and is serviced regularly. The PCV was also swapped out a couple of weeks ago.

    when i had a boost leak my MPG went down to about 25mpg. Pretty common if you've just been remapped. Check the intercooler hoses and tighten them all up as a start? then an ebay boost leak kit might help (worth buying anyway)

    Also removing the cat or fitting a sport Cat seems to make a big difference on our cars. as much as 5mpg.
