I have a 2006 A6 3.2 Quattro with push button start. My wife drove my car today and she used the key instead of the button. Now, it will not turn off. I have tried driving it around and stopping to turn off the car in various places, but the accessories and lights continue to work, even after getting out of the car. I even waited 20 minutes and when I opened the door, the radio was still on. Does anyone have any ideas?

 

Finally got it to turn off. Had to jiggle the ignition switch. Now getting a message that I have an ignition switch malfunction.
