    I just averaged ~23 mpg on my last fillup which was a mix of highway and city traffic. This is actual data, not the computer guessing.

    What are other's getting under mixed conditions? What did the 'book' suggest the engine should get when the cars were new?

    My average mpg shows at 26 on the trip computer my mate has the same car as me (a3 quattro) and he gets 32? thing is that i rarely give it the beans i mostly drive it as economically as possible. what could cause poor mpg? could this be anything to do with the maf? i don't expect the mpg to be great but from the threads I've read on here there are people with mapped s3's getting the same if not better mpg as me and mine is completely standard?

    Think the weight more than anything makes the difference.

    Think its largely accepted the quattro costs you anywhere between 5-10mpg.

    My a3 FWD 1.8t is getting 30mpg on the motorway atm, which i think aint right, probably needs new MAF.

    Talking of which, anyone used the ebay MAFs going for ~£60 ?

    The S3 'Quattro' is pretty much the same as my Fwd A3 for fuel, both remapped.

    Hardly any difference at all...

    Both Aprox 27-28 mpg with mixed driving...

    How can you test to be sure it's the MAF?

    :shrug: I'm no expert, i would of thought that if there was anything wrong with the maf, that there would be other side affects other than bag mpg. what about DV? i've noticed that the engine bogs down for the slightest moment after gear changes, apparently this is caused by the DV? pffft i'm waiting for someone to educate me. :think:

    I'm getting a **** 20ish MPG at the moment, a steep fall off from 28MPG ish (according to the DIS). I'm not panicing 'till the snow's gone though as I don't reckon that's helping it too much!
