    Hi all,

    The range of fuel left on my A3 has always been a bit iffy, at 1/2 a tank it often used to read 0 miles left and beep, so a good 3 or 4 times i filled it and it took about 30 litres, so with the Quattro holding 60 litres my conclusion was the gauge actually works, but the computer it incorrect.

    Recently i have been running it lower and lower, and managed to get it to read 70 odd miles left, after putting £10 in, and the gauge reading a bit under half.

    All was ok, until i ran out of fuel the other day :sadlike: to be fair the range had been on 0 for a few days, but the gauge was a little over a 1/4.

    So where do i go from here?! Could it be the tank sender, £155 my mate can get one from VW, or the unit in the dash, which is even more!

    Any advice on how to sort this would be much appreciated.

    Cheers

    Dave

    £155 for a tank sender, are you having a laugh??

    I had one in my A4 go and that was about £35, im sure its the same as the one in the S3, surely it cant be £120 more???
