I've had my A3 for a month when it wouldn't start straight away, I turn the ignition on wait for the glow plug light to go out then it would take a minute or so of winding it over before it fired up. I took it back to the dealers and they couldn't find any faults with there computer, they said monitor it so I did. Then today it wouldn't start again, so called the Audi roadside assistance. They plugged in their computer and it showed no faults but it wouldn't start. So there is a fault. Its back at the dealers and they can't find a fault either, I'm going round in circles. Has anyone else experienced this problem?
