No.. Bought it in Oct 2009.
After a couple of months noticed exactly as you describe.Thought oh well,but you know something is not 100%.
In april 10.would not fire up (Parked,slightly nose up), Workmen laughed when an Audi wont start,and had to join AA. He checked everything,of course couldnt find anything. After turning key for what must have been 15 - 20 secs decided to awake from sleep.
In the meantime.had it remapped to 215bhp/316torque.now got an amazing new car,acceleration ridiculous,and of course only FWD.so only really liked to go left or right (badboy). about a month later. didnt really want to start,felt as if starved of fuel (been left for 3 days) anyway down to audi for diagnostic,of course nothing wrong,only showed something changed from factory setting. Get in ,I've got my old car back.***.
After getting it put back again to badboy mode.No more trouble for maybe 1 year. then same old hesitation,only very slight tho.
In July 2011 bought RS3 and sold A3 to sons partner for bargain 7k (prob 7/800 off).then disaster 5 days later .he rings me,she totally broken down in Truro.dead as the parrot in the Python sketch.RAC man does quick test and shows injector problems and has to be towed away. They are not much pleased with me now,am i going to cough up.
Anyway a stroke of good fortune saved the day,I find on this forum.the recall for 56 2.0tdi's.Audi replaced them all 2 days later ...no charge.........No longer a problem.
