I have an 2 month old 2008 A3 S-Line. Filled up when fuel light indicator went on.
Upon re-start the fuel gauge stayed at 1/8 even though the tank was full. Low fuel Indicator light stayed on.
Pulled over and turned car off and turned it back on, now the gauge went to zero.
Called the dealership and they told me to cycle starts at least 4 times.
The gauge worked (went to 8/ after first restart.

Anyone else have this problem and if so, is it ongoing.
