    Hi
    It could be This
    It certainly was on mine. It may be worth also just checking the connections are ok on the fuel sender before you dive into the tank.

    I would say it was the issue brought up above, quite common on A4s I believe. Mine does a similar thing, gets to certain points on the gauge and drops to nothing, and the DIS follows suit as they're all tied together, drive a little further and it pops back up again, and the mpg etc registers again. An easyish fix, a cheap one at least for once. Never bothered fixin it though on mine yet as I jsut got used to it. One day!

    Mines been erratic this last week, i went to tesco`s and had 30 miles on DIS and when I came out the petrol light came on and I had 5miles left, luckily i was beside the petrol station. Although I gotta admit its weird seein it lose 25miles and previously this week the needle strangely had a bit of a wobble when I was sitting idle while waiting for the wife to finish.

    Also I have done the same procedure on a Peugeot 405D and the black cap is hellishly tight, although sitting above a fuel tank it is understandibly so.

    the fuel sender doesnt emit a voltage?

    its a resistor which changes with the fuel level

    If you measure the resistance of the sender with the wiring disconnected you should see whats going on.

    looks like a fuel pump sender problem. done a full system check on display unit the gauges are not faulty. so new sender required it must be that thin wire that has snapped.

    did you actually read the thread linked to above?

    The resistor is likely fine, there is a wire that attaches the moving part to the rest of the sender which wears out and breaks

    http://vader.inow.com/~drbob/fuel.html

    this link shows you what to do, might take some time, but it wont cost anything to fix.

    http://vader.inow.com/~drbob/fuel/sendingunit.jpg

    there you can see the wire, in brown, and it looks knackered. The resistor is the stripey bit on the white casing at the top of the photo, completely seperate things
