My hazard lights started flashing with out the hazard buttons being pressed. After about a mile they went off. Has anyone had this happen or know what it could mean? I looked through my owners manual to see if it was some sort of malfunction indicator but found nothing. The car ran fine when they were flashing. When I went to get in the car I thought I heard an unfamiliar beep, but I thought it may have been another car in the parking lot.

 

No doubt a gremlin in your A3.
