Hmmm I'n not an expert, but 2 lines to follow, firstly and most likely is it the transponder in the key, I've seen this problem on other makes not on Audis, where the key will work the ignition but will not allow it to turn over (or start if it were bumped) due to the transponder in the key not transmitting or the car not receiving. (not to be confused with central locking completely seperate and this function not reliant on battery in key) sometimes this is caused by local interference (something on your key ring / fob) or it maybe just faulty. Have you tried another key, does the fault happen with both keys or just one? also remove everything from your ring try the key on its own.
Failing that, then it could be solenoid / starter motor fault, when you are holding the key in that start postion is anything flashing on the dash, is there any click from anywhere in the car? (you will need to be in a quiet spot with climate/radio etc turned off to hear it) if you do hear a click then its not transponder but solenoid / starter motor.It could also be the key barrel itself.
Also others on the site would recommend you 'plug-in' to download any fault codes from the on board computer, I would hope your dealer has tried that and found nothing, but maybe worth checking.....
