    2.0t is good, get between 20-30mpg dependant on if stuck in traffic or not, higher on motorways.

    Towing the caravan at the legal limits (60mph on dual carriageways/motorways and 50mph on other roads, I'm getting a consistent 27mpg. Driving pretty sedately solo that goes up to about 35mpg. The best I've ever seen was 44.5mpg on a leisurely drive around the Camargue on a hot day.

    Can't say my 3.0 tdi quatto is noisey, quit the opposite, and I'd certainly never go back to a gasser.

    If you go 2ltr and trying to save fuel go for the front wheel drive variant rather than the quattro as the quattros are heavier and use quite a bit more juice. Even thou the fwd have a larger fuel tank than the 4wd.

    Once you have been used to the superior driving characteristics and torque of a modern diesel you should test drive a petrol powered car for at least a day to see if you can live with it . A pal got average 22mpg around town which dropped to 19 mpg in winter around town in a 2.0tfsi A4

    Weedy torque , noisy at speed ( bit quieter at idle ) , need to rev to make any progress , not relaxing to drive as you need to keep the engine on the ball . They are £££ cheaper on the used market for a reason .

    Hi i have a 3.2 Quattro for weekly motorway which can get 350 miles per tank and then i nick the S4 kids taxi for the weekend which is lovely and noisy and burns lots of fuel, best of both for me.

    2.0 FSI (53 plate) 2wd Avant - 32 overall - high 30's on a run as long as I keep it around 60. Sitting at 70 gives me 35 ish. Given the choice, I'd go diesel having had a 54 plated A4 2.0 as a lease car back in the day. Mind you, that would have probably been one of the ones which eventually died when the oil pump drive gave up the ghost. Had a 2.0 Vauxhall as a loan car some weeks ago, and while I'd not want it as my own car, I have to say the performance was way in excess of the Audi. Mike.

    The trouble with the recent diesels is the DPF. If you don't do the long runs e.g. motorway, dual carriageway, they can't regenerate, get blocked and cause problems. Same with the EGR valve, gets bunged up and then you get rough idling and loss of power. For me, it just wouldn't work, the DPF light would be on all the time.

    Stage one 2.0 TFSI and average is around 28mpg. Upwards of 36mpg on a motorway run and around 28mpg for town driving.
    Normally 400 miles to a tank of mixed driving.

    I couldn't agree more. I wanted a diesel purely for the fuel economy (diesel is substantially cheaper than petrol in France where we do most of our annual mileage and 98ron can be difficult to find, especially at supermarkets) but the fear of the dreaded DPF persuaded me that petrol was the option best suited to my particular circumstances. I also took the advice of my local independent VAG specialist who said that he personally would not run a diesel because of all the problems he sees with them. It would only take one forced DPF regeneration or, heaven forbid, a DPF replacement to wipe out any fuel savings at a stroke.

    I'd have had a pre-DPF diesel if such a thing had been available but they were fitted to the convertibles long before the 2009 compulsory date and all the 2.5L cars I considered had massive mileages.

    It's horses for courses. You pays your money and takes your pick.

    It will be interesting to see what impact the new Euro6 emissions standards will have on the sale of diesel vehicles. There is a great deal of medical concern at present over high Nox emissions and potentially carcinogenic soot nano-particles from diesel exhausts that can enter the blood through the linings of the lungs.

    Not if you're stage 2+, 325lb/ft and with a miltek makes a beautiful sound ;)

    Wife has a 1.5 diesel qashqai with a tuning box from DTUK, no dpf on that engine and great mpg and actually not bad with the box on it..that's for long journeys now...

    Think if I was going on road trips etc I would go for the 3.0 tdi Quattro. I love my 2.0t fsi Quattro but it's not the best for long journeys etc. The 3.0 has a shed load of torque and is a serious cruiser, but you can also boot and really feel the kick. I've driven my dad's 3.0 tdi Quattro and in fairness it's a completely different car in terms of feel, power delivery and road hold, but 50+ mpg on a long run.... Who can complain.. My dad's driven mine and drive it hard! And once again mine is a weapon, but it wants to be driven that way all the time otherwise it's pointless. As standard mine is a good car, but not a long journey motor unless you have deep pockets!
    Good luck with your choice! :)
