Flat battery

Went to start this morning and the battery is as flat as the proverbial. No idea why - nothing left on overnight and the car is used daily. Worst of all as the car thinks the ignition is on the key will not release so I will have to wait with the car until Audi arrive. Anybody else had this happen and any theories?

Has happened to me once - a few days after delivery. Put it down to unfamiliarity with all the controls so poss leaving something on/open. Headlights??

Never happened since so maybe just an aberration.
Don't think you can leave the interior light or radio on as the car should shut down the lights and radio automatically after a set time.
