    Had my s3 for about 2 weeks now and I think I've done about 300 miles and it's cost me not far off £100
    Over yesterday and today I put £45 of fuel in and the light came on after 155 miles - mostly driving about 50 with the odd little blip .. Is this normal or is there something wrong ??
    Also just filled up £62 and it's only showing as 3/4 tank my heads baffled it just doesn't seem right
    Cheers

    More info...

    Is it mapped?

    On average £20 the motorway should get you 150 if "sensible"

    £60 takes me about 375 miles on average, sounds like you have a problem, get it on VAG-COM and see whats amiss

    Straight through system including decat
    Remap
    That's all I know off .. Mpg calculator was averaging 35 mpg that's what I don't get .. But fuel gauge was playing up the other day going from full tank to 0 then upto half and so on so was told the receiver was goosed but clearly it's actually using that much as £63 must fill the tank ??
    No smell of fuel so definatly not a fuel leak

    Check if you have 4 bar fuel presure regulator, this shows better mpg on the dash but in fact I would say it's up by 8-10mpg. so if you get 36mpg it's more like 26. Decat does not help at all.

    Well I would say to anyone who has a 4 bar. the standard one is 3 bars. but that's my little finding with the FPRs I have used.

    Yeah this cold weather does make a noticeable difference in mpg, mines dropped to 48mpg! Only just getting 600 miles / tank now, bloody winter. On the plus side you s3 boys must be noticing a nice increase in power with the plentiful cold dense air?

    James, Thats a daily drive to work of 40 miles each way on the motorway at about 80, mixed in with few local journeys of around 5 miles or so, if out of the way fo the boys in blue and giving it beans it drops but not by much, a banzai trip halfway across Devon and on up to Guildford last August early on a Sunday morning returned 27 mpg and gave 305 miles out of a tankful. I've never ever had less than that from a tankful. Hope you get it sorted.

    I've filled the tank up to the brim couldn't get anymore in and it's only showing 3/4 tank ?? Maybe it is the sender ?? How much does it cost everyone else to fill an s3 from reserve ?

    Oh I don't know haha have to clean out the sender and go from there .. Fuel pressure regulator under the bonnet ?
    So If a full tank is £70 that means I've definatly used £45 on 150 miles thought the tank might have been bigger Eg £80 so would have been the sender not working properly :-(

    What size wheel have you got on ??? I know I get approx 30 miles less to a tank of fuel with 235/19. I get 300 to 330 on a full tank to empty.

    sounds like the sender, its under the back seat behind the driver, run the tank down then pull the pump to a angle to remove the circuit board like sender. I cleaned mine up a few weeks ago and its reading fine now.

    Typically i've been getting 280 miles to a full tank of V-Power (£72+). DIS showed roughly 25mpg.
    Last full tank got me 250 miles :( - DIS showing 22mpg.

    I do a lot of short journeys, leave it to warm-up and cool-down, commuting in stop/start traffic and it's hilly around here to be fair.
    Still getting it checked/possible replacement thermostat on Monday.

    wider tyre = greater resistance = less mpg

    My brother in law fitted some stupidly wide wheels to a old corsa that killed the mpg totally.

    I get 25 miles to a fiver and around 45 miles to a tenner (don't even criticise the maths as I know it doesn't add up lol) round town or on short journeys with my Revo (variable - it'll do what it wants) map in the Red car and about 340 miles to a full tank on the motorway.

    The black car does about 15 miles to a fiver if I'm lucky!
